Research Progress in the Regulation of the ABA Signaling Pathway by E3 Ubiquitin Ligases in Plants.

E3 ubiquitin ligases (UBLs), as enzymes capable of specifically recognizing target proteins in the process of protein ubiquitination, play crucial roles in regulating responses to abiotic stresses such as drought, salt, and temperature. Abscisic acid (ABA), a plant endogenous hormone, is essential to regulating plant growth, development, disease resistance, and defense against abiotic stresses, and acts through a complex ABA signaling pathway. Hormone signaling transduction relies on protein regulation, and E3 ubiquitin ligases play important parts in regulating the ABA pathway.

Advances in the Mining of Disease Resistance Genes from and the Utilization in Wheat.

is one of the malignant weeds that affect wheat production and is also the wild species ancestor of the D genome of hexaploid wheat (, AABBDD). It contains many disease resistance genes that have been lost in the long-term evolution of wheat and is an important genetic resource for the mining and utilization of wheat disease resistance genes. In recent years, the genome sequence of has been preliminarily completed, which has laid a good foundation for the further exploration of wheat disease resistance genes in .
