(Adopted from Chen et al., 2021) While, the TCONS_00029371/miR408-5p/LOX2 regulatory axis has been revealed as a core element in rice drought resistance strategies. In this regulatory axis, the long non-coding RNA TCONS_00029371 functions as a competitative endogenous RNA (ceRNA), fine-tuning the expression level of LOX2, thereby regulating lipid peroxidation and antioxidant responses to enhance rice drought tolerance. This discovery provides a new perspective on how rice adapts to drought conditions (Li et al., 2022). The integration of transcriptomic, metabolomic, and physiological data has revealed genotype-specific regulatory mechanisms affecting rice development and response to water deficit, highlighting the importance of cell wall metabolism and other fundamental processes (Favreau et al., 2023; Wang et al., 2023).
