An E2-E3 pair contributes to seed size control in grain crops

Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Published: May 29, 2023

Abstract Understanding the molecular mechanisms that regulate grain yield is important for improving agricultural productivity. Protein ubiquitination controls various aspects of plant growth but lacks understanding on how E2-E3 enzyme pairs impact in major crops. Here, we identified a RING-type E3 ligase SGD1 and its E2 partner SiUBC32 responsible control Setaria italica . The conserved role was observed wheat, maize, rice. Furthermore, ubiquitinates brassinosteroid receptor BRI1, stabilizing it promoting growth. Overexpression an elite haplotype improved by about 12.8% per plant, promote complex biological processes such as protein processing endoplasmic reticulum, stress responses, photosystem stabilization, nitrogen metabolism. Our research not only identifies SiUBC32-SGD1-BRI1 genetic module contributes to improvement also provides strategy exploring key genes controlling traits Poaceae crops using model system.

Abiotic Stress in Rice: Visiting the Physiological Response and Its Tolerance Mechanisms

Plants, Journal Year: 2023, Volume and Issue: 12(23), P. 3948 - 3948

Published: Nov. 23, 2023

Rice (Oryza sativa L.) is one of the most significant staple foods worldwide. Carbohydrates, proteins, vitamins, and minerals are just a few many nutrients found in domesticated rice. Ensuring high constant rice production vital to facilitating human food supplies, as over three billion people around globe rely on their primary source dietary intake. However, world’s grain quality have drastically declined recent years due challenges posed by global climate change abiotic stress-related aspects, especially drought, heat, cold, salt, submergence, heavy metal toxicity. Rice’s reduced photosynthetic efficiency results from insufficient stomatal conductance natural damage thylakoids chloroplasts brought stressor-induced chlorosis leaf wilting. Abiotic stress farming can also cause complications with redox homeostasis, membrane peroxidation, lower seed germination, drop fresh dry weight, necrosis, tissue damage. Frequent movements, rolling, generation reactive oxygen radicals (RORs), antioxidant enzymes, induction stress-responsive enzymes protein-repair mechanisms, osmolytes, development ion transporters, detoxifications, etc., recorded potent morphological, biochemical physiological responses plants under adverse stress. To develop cultivars that withstand multiple challenges, it necessary understand molecular mechanisms contribute deterioration stresses. The present review highlights strategic defense adopt combat stressors substantially affect fundamental biochemical, mechanisms.
