UNASSIGNED: MiRNAs play crucial roles in many aspects of plant development and the response to the environment. The @entity71226 family has been shown to participate in the control of flowering time and the response to abiotic stress. This family regulates the expression of @entity30387 ( @entity30387 )-like transcription factors in @entity958 . In the present study, @entity1460 ( @entity1460 .) @entity71227 , a member of the @entity71226 family, and its target gene were investigated for abiotic stress responses in transgenic @entity958 . gma- @entity71227 was induced by @entity2271 ( @entity2272 ) treatments and abiotic stresses, including salt and water deficit. 5'-RACE (5'-rapid amplification of cDNA ends) assays indicated that @entity71226 c directed Glyma01g39520 mRNA cleavage in @entity1460 . Overexpression of gma- @entity71227 in @entity958 resulted in reduced leaf water loss and increased survival rate under stress conditions. Meanwhile, the root length, germination rate, and cotyledon greening of transgenic plants were improved during both high salt and water deficit conditions. In addition, transgenic plants exhibited @entity56 to @entity2272 during both the seed germination and post-germination seedling growth stages. Stress-related physiological indicators and the expression of stress/ @entity2272 -responsive genes were affected by abiotic treatments. The overexpression of gma- @entity71227 in @entity958 promoted earlier flowering compared with the wild type through modulation of the expression of flowering genes, such as FT and LFY during long days, especially under drought conditions. Glyma01g39520 weakened @entity2272 sensitivity and reduced the tolerance to drought stress in the snz mutant of @entity958 by reducing the expression of @entity13125 and @entity13126 . Overall, the present results demonstrate that gma- @entity71227 confers water deficit and salt tolerance but increased @entity2272 sensitivity by regulating Glyma01g39520, which also accelerates flowering under abiotic stresses.
