Summary: Cold stress is a significant abiotic stress condition that hinders plant growth and development. In this study, the negative role of MPL1 and LIP1 triacylglycerol lipases in cold stress response was elucidated. These lipases may serve as potential candidates for breeding cold-tolerant crops through genome editing technology.

Summary: This study provides insights into the characteristics of the LbaBBX gene family in wolfberry. The LbaBBX genes are highly responsive to light, phytohormones, and stress conditions, and have orthologs in tomato, eggplant, pepper, and Arabidopsis. LbaBBX2 and LbaBBX4 play key roles in the regulation of carotenoid biosynthesis.

Summary: Pattern-triggered immunity (PTI) is a vital defense mechanism used by plants against pathogen attacks. Heterotrimeric G proteins, particularly XLG2 and XLG3, play a positive role in regulating plant immunity, while XLG1 was previously believed to be non-functional. However, this study shows that all three XLGs function redundantly in PAMP-triggered MAPK activation and plant immunity. The triple knockout mutants of xlg1 xlg2 xlg3 exhibited compromised resistance against pathogen infection.

Summary: Salt stress causes ionic toxicity, osmotic stress, and oxidative stress, directly affecting plant growth and development. Plants perceive salt stress through the cell wall and coordinate effective responses. Some mechanisms underlying these processes have been elucidated.

Summary: In this study, a tomato (Solanum lycopersicum) GATA gene, SlGATA17, was found to play an important role in the tolerance to salinity stress. Its expression was induced by heat, cold, ABA, ACC, and IAA treatments, but inhibited by NaCl and PEG treatments. It was also discovered that SlGATA17 interacts with the tomato transcription factor SlHY5, and SlHY5 negatively regulates SlGATA17 expression by binding to the GATA-box of its promoter. The SlHY5-SlGATA17 module may function as a regulatory component in response to abiotic stress.

Summary: The gene AtSYP81 in Arabidopsis thaliana plays a critical role in root growth and development by regulating peroxisome- and peroxidase-mediated ROS homeostasis. Knockdown of AtSYP81 resulted in reduced root meristem activity and disruption of root stem cell niche identity. Transcriptome analysis revealed changed expression of class III peroxidases, adding evidence of the regulatory role of AtSYP81 in ROS signaling.

Summary: Arabidopsis DXO1 is an essential component in the methylation of the guanosine cap to form the m(7)G cap. It activates RNA guanosine-7 methyltransferase (AtRNMT1) to catalyze this conversion. This study reveals an important mechanism in m(7)G capping in plants and the role of DXO1 in this process.

Summary: Triacylglycerol Lipase a10 (SlTGLa10) negatively regulates cold tolerance and growth in tomato. SlTGLa10 overexpression plants are more sensitive to cold stress with higher oxidative lipid levels, ion leakage, and reduced antioxidant enzyme activity. SlTGLa10 knockdown plants show improved cold tolerance and growth phenotypes.

Summary: This study identified and analyzed the 14-3-3 family genes in tomato and revealed their importance in biological processes and response to abiotic stress. The Sl14-3-3 genes in tomato were found to be responsive to heat and osmotic stress, and localized in the nucleus and cytoplasm. Overexpression of the SlTFT6 gene improved thermotolerance in tomato plants. This study provides valuable information for further investigation into the molecular mechanisms underlying plant growth and response to abiotic stress in tomatoes.

Summary: The accumulation of 4-Methylumbelliferon (4-MU) in the roots of vigorous rootstock under drought conditions was found, and its exogenous application to the roots of dwarfing rootstock improved their root biomass, root-to-shoot ratio, photosynthesis, and water use efficiency. Furthermore, the treatment of 4-MU increased the relative abundance of beneficial bacteria and fungi in the rhizosphere soil microbial community.

Summary: A smartphone-assisted and non-enzymatic colorimetric biosensor was developed for rapid monitoring of multiple organophosphorus pesticides (OPs). The biosensor utilizes the enhanced effect of aptamer on the catalytic ability of octahedral Ag2O to achieve accurate and stable detection of pesticide residues. The color change of the solution can be easily converted to RGB values by a smartphone, enabling quantitative and rapid detection of multiple OPs.

Summary: Multiprotein bridging factor 1 (MBF1) is a family of transcription coactivators that play a crucial role in the response of plants to abiotic stress. This study analyzed the genomic data of five Solanaceae plants and identified 21 MBF1 genes. The expansion of MBF1a and MBF1b subfamilies was attributed to whole-genome duplication, while the expansion of the MBF1c subfamily occurred through transposed duplication. Gene expression analysis showed that SlER24 was induced by various stress conditions and its overexpression enhanced salt tolerance in tomato. SlER24 also upregulated salt stress-related genes and enhanced antioxidant enzyme activity to reduce reactive oxygen species accumulation and plasma membrane damage under salt stress.
