The review discusses the significant progress in understanding the genetic basis of sorghum’s agronomic traits, its tolerance to various stresses, and its potential for addressing food and feed security.
Recent advancements in genomics have led to the complete telomere-to-telomere (T2T) assemblies of two sorghum genomes. These comprehensive assemblies provide valuable insights into the genetic landscape of sorghum, enhancing our understanding and enabling significant agricultural and biological discoveries. The recent studies are below : Wei et al (April-2024) – 10.1002/imt2.193 & Deng, Y et al (May-2024) – 10.1016/j.xplc.2024.100977.
Insect feeding on plants triggers complex physiological and metabolic changes, including alterations in lignin biosynthesis and auxin signaling, which enhance plant defense mechanisms against phloem-feeding insects, such asaphids.
Pearl millet, a resilient C4 crop crucial for food security in arid regions, faces challenges in yield and shelf life due to environmental stresses and rapid flour rancidity, which can potentially be mitigated through genetic engineering targeting phospholipase genes.
Sorghum seed development involves complex molecular processes, including tissue-specific gene expression and metabolite accumulation, which are critical for improving grain quality, yield, and climate resilience.
Researchers from Shijiazhuang, China identified and characterized seven PRE genes in sorghum, highlighting SbPRE4’s role in enhancing aphid resistance through jasmonic acid signaling.
This study identifies and characterizes 32 phospholipase A (PLA) genes in Sorghum bicolor, revealing their diverse roles in plant growth, defense, and stress response, with significant implications for improving sorghum production in semi-arid regions.
This study identified and characterized the COMPASS-like complex in sorghum, revealing unique ASH2 gene duplications and novel transcriptional activation activity in RbBP5, suggesting distinct regulatory mechanisms for gene expression in sorghum compared to other plants.
