The coordinated regulation mechanism of rice plant architecture and its tolerance to stress

Abstract

Rice plant architecture and stress tolerance have historically been primary concerns for rice breeders. The “Green Revolution” and super-rice breeding practices have demonstrated that ideal plant architecture can effectively improve both stress tolerance and yield. The synergistic selection and breeding of rice varieties with ideal architecture and stress tolerance can increase and stabilize yield. While rice plant plant architecture and stress tolerance are separately regulated by complicated genetic networks, the molecular mechanisms underlying their relationships and synergism have not yet been explored. In this paper, we review the regulatory mechanism between plant architecture, stress tolerance, and biological defense at the different level to provide a theoretical basis for the genetic network of the synergistic regulation and improvement of multiple traits.

Integration of mRNA and miRNA analysis reveals the molecular mechanisms of sugar beet (Beta vulgaris L.) response to salt stress

“…Using miRNA-mRNA integration analysis, recent investigations have broadened our knowledge of how plants respond to stress 14 , 39 , 42 , 51 . This current study identified several miRNA-target gene pairs that respond to salt stress and developed a regulatory network using DEMIs and DEMs.…”

“…This is particularly important in transcriptome studies of species where genomic information is relatively limited 11 . Transcriptome sequencing approaches have been widely applied in agriculture, including the exploration of resistance genes in animals and plants 12 , 13 , the study of resistance 14 , and metabolic mechanisms 15 .…”
