Enhancing resistance of rice

Prime editing is a novel and universal CRISPR/Cas-derived precision genome-editing technology that has been recently developed. However, low efficiency of prime editing has been shown in transgenic rice lines. We hypothesize that enhancing pegRNA expression could improve prime-editing efficiency.

Serotonin, originally identified as a neurotransmitter in mammals, functions as an antioxidant to scavenge cellular ROS in plants. In rice, the conversion of tryptamine to serotonin is catalyzed by SL (sekiguchi lesion), a member of cytochrome P450 monooxygenase family.

Bacterial blight of rice, caused by Xanthomonas oryzae pv. oryzae (Xoo), is a devastating rice disease in Southeast Asia and West Africa. OsSWEET14, encoding a sugar transporter, is known to be a major susceptible gene of bacterial blight targeted by four different transcription activator-like (TAL) effectors from either Asian or African Xoo strains.

Rice (Oryza sativa) productivity is adversely impacted by numerous biotic and abiotic factors. An approximate 52% of the global production of rice is lost annually owing to the damage caused by biotic factors, of which ~21% is attributed to the attack of insect pests. We have developed transgenic pyramided rice lines, endowed with enhanced resistance to major sap sucking insects, through sexual crosses made between two stable transgenic rice lines containing Allium sativum (ASAL) and Galanthus nivalis (GNA) lectin genes.

In Bihar rice is a major food crop and has more than 5.14 M ha area. Recent years environmental stress becoming major threats to rice cultivation and adversely affecting the productivity of crop. Drought resistance varieties and some microbes have proved their potential in mitigation of stresses and enhancing the rice yield under stress condition. In this study, two Trichoderma isolates were tested with three drought tolerant varieties i.e. Sahbaghi dhan, DRR44 and Neelam.

Spotted-leaf mutants are important to reveal programmed cell death and defense-related pathways in rice. We previously characterized the phenotype performance of a rice spotted-leaf mutant spl21 and narrowed down the causal gene locus spl21(t) to an 87-kb region in chromosome 12 by map-based cloning.

Jacalin-related lectins in plants are important in defense signaling and regulate growth, development, and response to abiotic stress. We characterized the function of a rice mannose-binding jacalin-related lectin (OsJAC1) in the response to DNA damage from gamma radiation.

Endophytes are microorganisms mostly bacteria and fungi that lives partially or completely its life cycle inside living plant tissue without causing adverse negative symptoms. Endophytes play a major role in structuring shaping processes of plant such as colonization, competition, coexistence and soil nutrient dynamics. Some endophytes promote growth of their host plants by enhancing the host‟s ability to take up nitrogen and phosphorus.

Transformation is the process by which the genetic make-up of an organism is altered by the insertion of new gene into its genome. As most of the agronomic traits are polygenic in nature, so the integration of multiple genes is required to manipulate the complex, polygenic metabolic or regulatory pathways, while ensuring their stable inheritance and expression in succeeding generations. There are various methods for multiple gene transformation but co-transformation method has proved more efficient and transplastomic technology can be used whenever have an option.

Yellow stem borer has been identified as a major insect pest of deepwater rice, causing severe yield losses. Bt gene(s) from Bacillus thuringiensis have been proven very effective in pest resistance program. The use of transgenic plants expressing Bt gene(s) is now occupied effective approach to control insect infestation. We have successfully introduced a synthetic cryIA(b) gene into embryogenic calli of a deepwater indica rice variety, Vaidehi, by using the biolistic method of transformation.
