Outputs
Target Audience:This project has a wide range of target audiences due to the increased awareness among the public regarding the impact of climate change on food security. These audiences are rice growers, researchers from the USA and other parts of the world, graduate and undergraduate students, farm consultants, extension agents, high school students and teachers, policymakers, state commodity board members, and consumers. Students were enrolled in seminars focusing on climate change and food security. Several Co-PDs participated in field days, demonstrations, consultants' meetings, and producers' meetings in multiple states and highlighted the background and importance of the ongoing research on the development of climate-resilient varieties, climate-smart production practices, and application of digital technology for improving sustainability and profitability of the farming enterprise. High school students participated in lab activities of a Co-PD with expertise on artificial intelligence during the summer of 2023. The PD and Co-PDs presented posters and oral presentations in meetings and technical working group meetings where the audiences were researchers, rice growers, members of the rice industry and USA Rice Foundation, USDA scientists, consultants, extension agents, personnel, and graduate students. Development of the CRISP-RICE Website and participation in social media (Facebook, Instagram, podcasts) helped us to engage with the public about the project activities and updates. Changes/Problems:Since the processing of sub-awards took some time, there was a delay in the start of the project activities. Two of our Co-Project Directors from LSU Agricultural Center and one from Mississippi State University left the organization during the reporting period. MSU already assigned Dr. Drew Gholson in place of Dr. Hunter Bowman. Lisa Fultz's activities are assigned to Dr. Jim Wang of the School of Plant, Environmental, & Soil Science of the LSU Agricultural Center. The approval for these changes from the SASProgram Leader is pending. In the case of Dr. Luciano Shiratsuchi, his funds will be used for the Project Evaluation Work which will now be done by Dr. Samuel Robison of the LSU Social Research and Evaluation Center. The processing of this sub-award is under process for getting internal and SAS Program Leader's approval. Since we already have one Co-PD with precision Agriculture expertise, this change will not impede our effort to accomplish the overall goal of the project. The recruitment of a postdoc with bioinformatics experience was slowed down because the selected candidate could not get a visa. We had to redo the searchand finally recruited the postdoc in December 2023. There was a delay in getting the Material Transfer Agreement to procure the japonica diversity panel from the LSU AgCenter Rice Research Station. Since few seeds were provided, the Project Director distributed the seeds to CO-PDs at Mississippi State University and the University of Arkansasfor multiplication. After growing the panel, it was found that there is a great deal of variation in flowering which will be a major obstacle to evaluating different types of abiotic stress evaluation. The Co-PD at the University of Arkansas is in the process of getting a tropical japonica panel from the USDA-ARS Dale Bumpers National Rice Research Center. This will be multiplied again in 2024 before the screening for abiotic stresses can be conducted. What opportunities for training and professional development has the project provided?The project provided training and professional development opportunities for nineteen graduate students who are working on the different research components including physiological and genetic mechanisms of abiotic stress tolerance, metabolomics and lipidomics, artificial intelligence, genetics and biological control of resistance to pests and diseases, application precision agriculture tools, forecasting of diseases, cover crops, and socio-economic impacts of climate-smart technology under the direction of the researchers from participating states in this project toward the development of climate-resilient varieties and climate-smart production practices. Three postdoctoral fellows were recruited to conduct bioinformatics and disease resistance research activities. Two research associates in this project will be trained in the evaluation of mapping populations and a diversity panel under different abiotic stresses such as salinity, drought, and heat stresses. Two high school students worked during the Summer of 2023 to learn about artificial intelligence in the lab of a Co-PD. A single credit-hour "journal club" course was developed in the CRISP-RICE project in which twelve students enrolled in the course in Spring 2024 to learn about agricultural sustainability through presentations and discussions of their work and updated literature associated with it. The project also provided opportunities to members of the CRISP-RICE including graduate students to participate in workshops, conferences, seminars, and field days, to enhance their knowledge and for professional development. How have the results been disseminated to communities of interest?The findings from this project were disseminated in multiple ways to reach the target audiences. There were 14 peer-reviewed publications, and three abstracts published by the members of the CRISP-RICE group. The CRISP-RICE researchers including the graduate students and postdocs made eighteen posters and oral presentations in multiple meetings and conferences: ASA-CSSA-SSSA Annual Meeting.

We developed the CRISP-RICE Website (https://www.lsuagcenter.com/topics/crops/rice/crisp-rice), and participated in podcasts, and radio talk (NPR) to educate the public about the importance of thisproject and the research conducted by our group to improve sustainability of rice farming. We are also maintaining our presence on social media to update the activities and events. Multiple Extension videos on climate-smart technologies were circulated through YouTube and several articles were published with LSU AgCenter and popular news outlets for the benefit of the stakeholders. Other important modes of disseminating the results from the project to the stakeholders are through participation in field days, working group meetings, consultant meetings, rice production school, and demonstrations. During this reporting period, Extension personnel in Mississippi organized five county production meetings, two rice planning and Delta rice meetings, and participated in seven podcasts. In the University of ArkansasRice Field Day, stakeholders were invited to see the demonstration plots for the impact of irrigation strategy on insect infestations. Contacts were made through in-person contacts (~500) and podcasts (~2500). During the field day, the USDA-ARS Co-PD highlighted the background and importance of the USDA-NIFA project's ongoing research work for drought and heat stress tolerance. During two rice field events Eagle Lake and Beaumont, Texas, the project findings were disseminated through field tours and oral presentations to stakeholders. A working group was organizedin Texas for extension agents of Texas for rice disease management. In Louisiana, climate-smart information was presented at several meetings including Parish Rice Production meetings, the Louisiana Consultants meeting, the Supreme Climate Smart meeting, and several field days. Each meeting ranged between 50 to 500 stakeholders and farmers. The benefits of alternative wetting and drying techniques, cover cropping, and the use of precision agriculture in current and future rice growing were discussed. What do you plan to do during the next reporting period to accomplish the goals?The following activities are planned for the next reporting period under all four objectives.

Impacts
What was accomplished under these goals?
The project accomplishments are summarized below under different objectives. Objective 1: We developed enterprise budgets for a representative rice farm that models the cost structure of alternative irrigation water management strategies: conventional flood, furrow irrigation, and alternative wetting and drying (AWD). Both discussions and interviews were held with stakeholders to gain an understanding of the trends, variations, and core issues, identify barriers to the adoption of climate-smart technologies, and obtain a representative sample of rice growers for conducting the survey. Objective 2: Seed increase of several mapping populations was done for genome-wide association studies (GWAS). An aus panel was procured from USDA-ARS for early morning anthesis and other desirable heat and drought tolerance traits. We collected leaf samples of salt-tolerant and susceptible genotypes for metabolomics, lipidomics, and Raman spectroscopic analysis. The protocol for extracting lipids and metabolites from leaf samples was standardized. We performed NMR and LC-MS to identify the metabolites and lipids after salt stress. We performed literature searches to identify the Raman molecular signature for plant leaves. We used EnsembleVEP to predict the functional consequences of genetic variants on the RGAP database (Nipponbare) and STAR to determine mutable components. Analysis of the whole genome sequence and RNA-seq data of a salt tolerant introgression line (IL), donor Nona Bokra, and recurrent parent Jupiter revealed 14 and 25 differentially expressed genes (DEGs) in the introgressed regions of the IL under control and saline conditions, respectively. The DEGs included genes belonging to DREPP family, sialyltransferase-like protein, cyclin-like F-box family, CELL WALL INVERTASE 1, and OsbZIP71, which were upregulated only in the IL and Nona Bokra but downregulated in the Jupiter under saline conditions suggesting their role in enhanced salt tolerance. The japonica panel was screened for early-stage low-temperature stress in growth chambers and for response to variable Co2 concentration using the Soil-Plant-Atmosphere-Research (SPAR) facility. Compared to the control, there was a detectable reduction in stomatal conductivity, electron transport rate, chlorophyll content, and nitrogen balance index.Two introgression line mapping populations were planted at Stuttgart for seed increase to conduct the alternate wetting and drying (AWD) studies. The japonica panel was grown at the greenhouse of the University of Arkansas Rice research station and LSU AgCenter Macon Ridge Research Station.Due to the wide variation in flowering time, it would be challenging to conduct field trials to evaluate tolerance to drought and heat stress. We are exploring an alternative panel from the USDA-ARS. A breeding line with enhanced seedling stage salt tolerance along with Jupiter was evaluated under varying concentrations at the Clemson University Coastal Research and Education Center (CREC). The line showed better adaptability capacity to maintain productivity in high-saline conditions. A major QTL for bacterial panicle blight (BPB) resistance was identified using bulked segregant analysisin the population developed from the Lemont x LM-1 cross. The whole genome sequences of Lemont and LM-1 (mutant) were generated and SNPs and indels were identified, filtered, and annotated to identify putative genes for BPB resistance. In a multi-parental population,genotyping with markers associated with each of the two QTLs (RGB2 of Kele and qBPB3.1 of Jupiter) resulted in the identification of plants with different QTL combinations. We identified kernel smut-resistant rice varieties. Hybrid varieties showed better resistance to kernel smut. Fifteen more isolates of kernel smut fungus were collected from Texas and Louisiana. The mid-boot was the best time and fungicides, Amistar Top, Tilt, and Dithane M-45, were equally effective for control of kernel smut in a field trial. Objective 3: We evaluated the sensor-based nitrogen technology (SBN) at two production fields, one under the rice-soybean and another under the rice-crawfish rotation system. Crop performance was better in SBN-adopted fields. Experiments using silica-solubilizing bacterial (SSB) strain indicated higher grain yield with the application of silicon in both rice-soybean and rice-crawfish rotation. Although cover crops experiments were established at three locations, rice could not be planted due to climate issues. We analyzed data from 37 separate field experiments conducted in Louisiana and concluded that varietal resistance can be incorporated into integrated management programs to reduce reliance oninsecticides. We are characterizing volatile emissions from rice panicles at various stages of panicle maturation and exploring the effects of these volatiles on bug behavior. The evaluation of two mapping populations revealed significant variation in susceptibility to rice water weevil (RWW) and Mexican rice borer (MRB). Cover crops were plantedtwo locations to investigate the impact of cover cropping on insect pest management in rice. The insecticidal seed treatments reduced the RWW and MRB infestation by approximately 50% in May-planted rice relative to March-planted rice. A separate multi-year study revealed insecticidal seed treatments provided minimal benefit to ratoon crops and foliar application of insecticides did not influence yields of the ratoon crop. Trials conducted in Arkansas revealed that there were more rice water weevil larvae in the AWD plots compared to the flooded plots and hybrid cultivars had increased infestation with RWW larvae. Seed treatments performed equally well in both irrigation strategies. Using transcriptomic analysis, we identified major rice genes involved in regulations of stress response and broad-sense resistance that were specifically induced upon seed treatment of the bacterial agent NA2. Greenhouse tests were conducted with the same RIL population to confirm the phenotypes evaluated in the field.We consolidated the historical data on disease intensity, yield, and grain quality into a single dataset. A new protocol to classify varieties' disease reactions was developed. This protocol uses the accuracy component of the breeder's equation combined with multiple mixed models to eliminate studies with low accuracy and to use the stability of the assessment. In a trial to evaluate nitrogen-use efficiency (NUE), both remote and proximal sensing techniques were used to collect data on plant height four times during the growing season and yield data at maturity. The remote sensing data collections were done at one on-farm location to complement the data at the Rice station. This experiment demonstrated UAV remote sensing as a promising technology to generate plant height data including time series data during the growing season and to examine detailed spatial variability in the field. We initiated evaluating machine learning technique-based image processing for efficient evaluation of crop stand density in the field. Objective 4: We conducted UAV demonstration at two locations in Louisiana. A web page for the project was developed. We produced 20 news releases and articles. Demonstrations showing the impact of irrigation strategy on insect infestations were organized for stakeholders in Arkansas. Texas extension activities included presentations on field days. The rice growers in Mississippi learned about water-conserving irrigation strategies in different meetings. Climate Smart information was presented at several meetings and field days. The benefits of alternative wetting and drying techniques, cover cropping, and the use of precision agriculture were discussed. Best management practices were followed in five rice research verification fields across Louisiana. Extension videos were produced, and articles were published with LSU AgCenter and other popular news outlets.
