Summary: This study demonstrates the important roles of PePYL6 and PePYL9 in enhancing ABA sensitivity and drought tolerance in Arabidopsis, by identifying and analyzing the PYL gene family in Populus euphratica. The transgenic plants overexpressing PePYL6 and PePYL9 exhibited increased ABA sensitivity, improved water use efficiency, and enhanced drought tolerance compared to wild type plants, providing valuable information for further investigation of the roles of other PePYLs in response to abiotic stress in poplar.

Summary: The study demonstrates the important role of Arabidopsis ORANGE (AtOR) in regulating ABA-dependent adaptive response to drought stress. Overexpression of AtOR significantly enhances drought tolerance in Arabidopsis by regulating the expression of ABA- and stress-responsive genes. The subcellular localization of AtOR protein in chloroplasts suggests its involvement in drought stress response pathways.

Summary: This study investigates the role of Arabidopsis TLP AtTLP2 in mediating abiotic stress responses. The results show that AtTLP2 plays intricate roles in ABA-dependent abiotic stress signaling by interacting with other proteins and regulating the expression of genes related to ABA. The findings provide insights into the regulation mechanisms of plant responses to salt, dehydration, and oxidative stress.

Summary: The study found that enhancing the expression of the rty gene in strawberry can improve plant tolerance to drought through promoting auxin and ABA accumulation, as well as increasing root production, trichome density, and stomatal closure. The transgenic approach can overcome the inherent trade-off between plant growth and drought tolerance, by enhancing water use efficiency and reducing water loss rate under water shortage conditions.

Summary: The study demonstrated the important role of RabA2b in plant response to water stresses, showing that its overexpression can enhance drought resistance in Arabidopsis. Furthermore, the study revealed that the subcellular localization of RabA2b can influence the proteome of the plasma membrane, leading to changes in stress-coping proteins and cell wall/cuticle modifiers. Overall, increased RabA2b levels affect the plasma membrane proteome and contribute to improved drought tolerance in plants.

Summary: Osmotic stresses such as drought and high salinity have negative effects on plant growth and productivity. Abscisic acid (ABA) accumulates in response to osmotic stress and enhances stress tolerance by triggering physiological responses through ABA signaling. B2-RAFs are essential for activating SnRK2s in an ABA-dependent manner under mild osmotic stress, while B3-RAFs enhance SnRK2 activity under severe stress conditions.

Summary: Climate change and overexploitation of groundwater resources pose challenges to water demand in agriculture, threatening crop productivity. To enhance future food security, crops with both high water use efficiency and high crop productivity are urgently needed. Recent studies have shown that plants can optimize carbon uptake per water transpired without reducing yields. The plant hormone abscisic acid (ABA) plays a key role in reducing leaf transpiration and increasing water productivity. Therefore, ABA and its more chemically stable agonists have the potential to improve crop water productivity.

Summary: Water stress can have a severe impact on plant growth, productivity, and yield. Plants have evolved various strategies, such as the modulation of abscisic acid (ABA) levels, to respond and adapt to stress. This study investigated the role of XER, a stress-responsive RING E3 ubiquitin ligase, in stress response. The results showed that XER plays a crucial role in promoting drought tolerance. The study also revealed the interaction between XER and CBF4, a negative regulator of ABA responses, stomatal development, and drought tolerance.

Summary: The transcription cycle of RNA polymerase II is regulated by cyclin-dependent kinases and protein phosphatases, with the phosphatases playing a crucial role in ensuring fine control of elongation and termination. The major phosphoprotein phosphatase family members, including PP1, PP2A, and PP4, have decisive roles in the transcription cycle, but there are still unanswered questions about their division of labor and their regulation by transcriptional kinases. CDKs have recently been identified as potential therapeutic targets, raising the possibility that phosphatases could also provide opportunities for new drug development.

Summary: Melon is an important diploid crop with diverse flavors due to its distinct volatile organic compounds. Metabolomic and transcriptomic analysis of two cantaloupe varieties revealed a shift in VOC profiles during fruit development from C5-C8 lipid-derived VOCs in early fruits to C9 lipid-derived VOCs, apocarotenoids, and esters in late fruits. This shift was accompanied by specific isoforms of lipid and carotenoid metabolizing enzymes and transcription factors related to fruit ripening and hormone signaling.

Summary: Overexpression of ZmLOX6 in Arabidopsis reveals its role in producing pentyl leaf volatiles (PLVs) and their effects on hormone content, plant growth, and interaction with aphids. ZmLOX6 is an unusual plant 13-lipoxygenase that functions as a hydroperoxide lyase and is involved in the synthesis of PLVs. Overexpression of ZmLOX6 leads to a chlorotic phenotype and induces similar phenotypes in nearby unaffected plants, suggesting airborne PLVs as the responsible signals.
