Consensus genomic regions associated with multiple abiotic stress tolerance in wheat and implications for wheat breeding

Scientific Reports, Journal Year: 2022, Volume and Issue: 12(1)

Published: Aug. 11, 2022

In wheat, a meta-analysis was performed using previously identified QTLs associated with drought stress (DS), heat (HS), salinity (SS), water-logging (WS), pre-harvest sprouting (PHS), and aluminium (AS) which predicted total of 134 meta-QTLs (MQTLs) that involved at least 28 consistent stable MQTLs conferring tolerance to five or all six abiotic stresses under study. Seventy-six out the 132 physically anchored were also verified genome-wide association studies. Around 43% had genetic physical confidence intervals less than 1 cM 5 Mb, respectively. Consequently, 539 genes in some selected providing 6 stresses. Comparative analysis underlying four RNA-seq based transcriptomic datasets unravelled 189 differentially expressed included 11 most promising candidate common among different datasets. The promoter showed promoters these include many responsiveness cis-regulatory elements, such as ARE, MBS, TC-rich repeats, As-1 element, STRE, LTR, WRE3, WUN-motif others. Further, overlapped 34 known genes. addition, numerous ortho-MQTLs maize, rice genomes discovered. These findings could help fine mapping gene cloning, well marker-assisted breeding for multiple tolerances wheat.

Exploring Omics Approaches to Enhance Stress Tolerance in Soybean for Sustainable Bioenergy Production

Published: Jan. 1, 2023

Soybean is a widely grown crop that utilized for food, animal feed, and biofuel production. However, the yield of soybean crops often limited by abiotic biotic stresses such as drought, salinity, pest infestations, so on. In this chapter, we discussed application omics technologies including genomics, transcrniptomics, proteomics, metabolomics to identify stress-responsive genes metabolic pathways in soybean. These approaches can help researchers develop stress-tolerant varieties through genetic engineering breeding strategies. Ultimately, use enhance stress tolerance could contribute sustainable bioenergy production increasing yields reducing environmental impacts agricultural practices.
