Summary: In this study, a WRKY transcription factor, MfWRKY40, was discovered in the resurrection plant M. flabellifolia, which showed early dehydration induction. Overexpression of MfWRKY40 in Arabidopsis enhanced the plant's tolerance to drought and salt stresses by promoting root length elongation, reducing water loss, regulating stomata aperture, accumulating osmolytes, and enhancing antioxidation ability.

Summary: Cronobacter malonaticus is a food-borne pathogen that can survive in powdered infant formula for a long time, indicating its strong resistance to desiccation. Transcriptomic analysis revealed that C. malonaticus has a universal adaptation strategy to withstand desiccation by accumulating compatible solutes, activating stress resistance-related regulators, suppressing protein export and bacterial secretion system, and reducing other survival functions. The downregulation of T6SS genes and increased survival in mutants after desiccation treatment suggest that T6SS negatively regulates desiccation tolerance.

Summary: Partial desiccation treatment (PDT) is an effective technology for promoting the germination and conversion of conifer somatic embryos (SEs). This study integrated lipidomics, transcriptomics, and proteomics analyses to reveal the molecular basis of lipid remodeling in Picea asperata SEs under PDT. Phosphatidic acid (PA) had a significant effect on SEs after PDT and was found to be the most critical lipid in the response to PDT. The activation of PLD alpha by PDT led to the increased PA content, which not only affected the physical and chemical properties of the cell membrane but also participated in plant hormone signal transduction. These findings provide insight into the molecular mechanism through which PDT promotes SE germination and fills the gap in understanding the mechanism of somatic embryo lipid remodeling in response to PDT.

Summary: Apple peel browning is a natural phenomenon that affects the appearance of fruits. Previous research has mainly focused on postharvest storage, while studies at the preharvest stage are rare. This study identified the role of MdLAC7 in preharvest apple peel browning and revealed the regulatory mechanism involving phenolics and flavonoids. Furthermore, it was found that light exposure inhibited the activity of MdLAC7, reducing peel browning.

Summary: This study confirmed the presence of finger-like colleters in Anthurium andraeanum, which is the first report of colleters in the Araceae family. The colleters were found in the apex of young leaves, spathes, and unexpanded cataphylls, as well as in various locations on expanded cataphylls. These structures develop early and senesce quickly, and they produce a polysaccharide-rich secretion. The discovery of colleters in Araceae has implications for understanding their functional roles and evolutionary significance.

Summary: The application of GA3 promotes the levels of endogenous IAA and IAA-AsP, contributing to the elongation of grape berries. GO enrichment analysis reveals that DEGs are mainly enriched in the cell periphery, external encapsulating structure, and cell wall. KEGG analysis shows that GA3 treatment positively regulates the signal transduction pathways for auxin, especially IAA, and brassinosteroid.

Summary: Nocardioform placentitis (NP) is associated with inflammatory signaling, toll-like receptor signaling, inflammasome activation, chemotaxis, and apoptosis pathways. Increased leukocytic infiltration in NP lesions is related to upregulation of matrix metalloproteinase and apoptosis-related genes. Additionally, NP is associated with downregulation of placenta-regulatory and angiogenesis-related genes, as well as upregulation of hypoxia-related genes.

Summary: Tomato trichomes serve as mechanical and chemical barriers against herbivores, and auxin treatment can increase the formation of specific types of trichomes on tomato leaves. Genes SlARF4, SlTHM1, and SlMYB52 play crucial roles in regulating trichome formation and providing tolerance to spider mites in tomato plants. The interplay between these genes and cyclin gene SlCycB2 modulates the formation of trichomes in tomato leaves through the R2R3 MYB-dependent auxin signaling pathway.

Summary: The SlCLV3-SlWUS signaling pathway plays a significant role in low light-induced abscission in plants. Low light induces the upregulation of the SlCLV3 gene, which in turn inhibits the expression of the SlWUS gene, leading to disruptions in auxin response gradient and increased ethylene production, ultimately resulting in organ abscission.

Summary: This study elucidates the antagonistic mechanism between auxin and jasmonic acid during tomato pedicel abscission. It was found that SlHB15A regulates abscission by inhibiting JA-Ile synthesis, while auxin inhibits abscission through the SlHB15A-SlJAR1 module. Additionally, flower removal increases JA-Ile content and impairs the inhibitory effects of auxin on abscission.
