Summary: This study evaluates the proteome changes in rice plants inoculated with ACC deaminase producing bacteria under salt-stress conditions. The findings suggest that inoculation with bacteria can enhance photosynthetic activity, antioxidant activities, and ethylene regulation related proteins, thus attenuating salt-induced apoptosis and sustaining plant growth and development.

Summary: The study found that the ethylene-signaling mutant ctr1-1 showed less negative effects under high salt stress due to enhanced auxin signaling, while the ethylene-insensitive mutant ein2-1 exhibited depletion in active auxins. The continuously operating ethylene-signaling pathway may be associated with increased auxin biosynthesis in ctr1-1.

Summary: The MsDAD2 gene was specifically induced in the salt tolerant alfalfa cultivar and its overexpression enhanced the salinity resistance of transgenic alfalfa by promoting the expression of NQO1 and Cyt b6/f, leading to reduced reactive oxygen species production. The expression difference of MsDAD2 may be linked to dynamic histone modifications in its promoter. This study highlights the importance of MsDAD2 as a target for improving salt tolerance in alfalfa breeding.

Summary: This study characterizes the role of the DUF584 protein AtS40-1 in regulating ABA and salt responses in Arabidopsis. Transgenic and mutant experiments reveal that AtS40-1 enhances ABA responses and inhibits salt responses. Quantitative RT-PCR results also show a correlation between AtS40-1 and the expression of ABA signaling regulator genes.

Summary: This study identified NIGT1.4 as a novel contributor to maintained root growth under salt stress through analyzing natural variation of primary root length in Arabidopsis. NIGT1.4 was shown to promote primary root growth in response to salt stress through interaction with SnRK2.2 and 2.3. Moreover, NIGT1.4 was found to induce the expression of ERF1, which regulates downstream functional genes for maintained primary root elongation.

Summary: Polyamines, particularly arginine decarboxylase (ADC) gene, play a crucial role in the growth, development, and stress resistance of plants. This study investigated the involvement of the CpADC gene in the response of cherry to drought stress. The results showed that upregulation of CpADC gene expression and increased putrescine accumulation enhanced the stress resistance of Arabidopsis thaliana.

Summary: To compensate for their sessile lifestyle, plants have developed adaptations at the level of subcellular trafficking to maintain cellular homeostasis and membrane integrity under osmotic stress conditions. The activity of flippases, such as P4-ATPases, is crucial for the formation of vesicles, which are involved in processes like endocytosis and secretion. Lack of flippase activity leads to defects in membrane and Golgi network, resulting in impaired vesicle formation and movement, and decreased intracellular trafficking flexibility, thereby affecting plant adaptation to osmotic stress.

Summary: The Y1805-specific LEA gene, TtLEA2-1, was identified and found to be highly and sensitively expressed under salt stress. It showed sequence identity with Thinopyrum elongatum and was mainly expressed in the roots. Interaction analysis revealed 48 candidate proteins that interact with TtLEA2-1, mainly involved in environmental information processing and metabolism. Overexpression of TaLEA2-1 in wheat increased salt tolerance.
