Summary: This study analyzed the self-regulatory mechanisms of foxtail millet in response to freezing stress. It found that longer freezing time led to increased damage, but the plant responded by increasing proline, soluble sugar, and soluble protein contents. The study also discovered the crosstalk between brassinolide signaling and starch and sucrose metabolism in foxtail millet's response to freezing stress.

Summary: In this study, a genome-wide association study of cold tolerance in rice seedlings identified four quantitative trait loci on chromosomes 1, 4, and 5. Candidate genes within these QTLs were discovered, including Os01g0357800, Os05g0171300, and Os05g0400200, which could potentially affect cold tolerance in rice. Further evaluation of these genes may lead to the development of cold-tolerant rice varieties in breeding programs.

Summary: Plant growth and development are regulated by selective protein synthesis and degradation. The AtPUB2 protein plays an important role as an E3 ligase in this process. Loss-of-function mutants of AtPUB2 did not show significant differences in growth, possibly due to redundancy with AtPUB4. However, overexpression of AtPUB2 led to early flowering, improved vegetative growth, and increased sensitivity to exogenous cytokinin. Moreover, AtPUB2 was found to be induced under oxidative stress and enhanced antioxidant enzyme activity, suggesting its involvement in oxidative stress tolerance.

Summary: OsMADS29 (M29) is a crucial regulator of seed development in rice and its expression is tightly regulated at transcriptional and post-transcriptional levels. This study reveals that calmodulin (CaM) interacts with M29 in a Ca2+-dependent manner, leading to localization of M29 in the cytoplasm. The interaction of CaM with M29 may also facilitate dimerization of two M29 monomers, suggesting a general regulatory mechanism for oligomerization and nuclear transport of MADS proteins.

Summary: Ca2+ signaling is crucial for perceiving and transmitting information in cells. The Ca2+-mediated CBL-CIPK module is a major sensor responder network for Ca2+ signaling, and its involvement in plant adaptation from aquatic to terrestrial habitats has been suggested. Experimental analysis showed that CrCBL1 protein interacts with Phototropin and Channelrhodopsin, and its expression is regulated by light. Comparing algal sequences, differences in CBL and CIPK proteins between aquatic and terrestrial plants were identified. Additionally, Klebsormidium CBL and CIPK genes were found to respond to abiotic stress, indicating their early role in terrestrial adaptations. Structure-based prediction and Ca2+-binding assays revealed a typical Ca2+-binding pocket in Klebsormidium's KnCBL1 protein. Overall, this study suggests that stress-responsive proteins facilitate crosstalk between Ca2+ and light signaling pathways during plant adaptation from aquatic to terrestrial habitats.

Summary: Drought and salinity, as abiotic stresses, have become frontier areas in agricultural research due to their potential threats to global food security. Soil salinity has severely damaged the production of staple food crops worldwide. To address these constraints, strategies have been developed to increase stress tolerance and mitigate the negative effects on crop productivity. Recent literature suggests promising approaches in cultivating smart crops for salinity and drought tolerance. The use of halophytes and associated microbes shows potential for both stress mitigation and soil reclamation. Advanced omics tools provide deeper insights into the interactions among halophytes, microbiomes, and the rhizosphere habitat. Mechanism-based evidence supports the application of halophytic plants and their associated microbial communities in bio-saline agriculture.

Summary: Reactive oxygen species (ROS) and calcium (Ca2+) signalling play important roles in plant growth, development, and defense. They function together with electric signals in directional cell-to-cell systemic signalling and even plant-to-plant communication. However, there is still limited understanding of the molecular mechanisms underlying the management of ROS and Ca2+ signals, as well as the synchronous and independent signaling in different cellular compartments. This review focuses on the proteins that may connect different pathways during abiotic stress responses, and highlights the crosstalk between ROS and Ca2+ pathways in cell signaling.

Summary: In this study, two important motifs, VXPX and LKNE, were identified at the C-terminus of ChR1. VXPX is a ciliary targeting sequence in animals, while LKNE is a well-known SUMOylation motif. The study showed that VMPS of ChR1 is essential for interaction with GTPase CrARL11 and revealed the presence of SUMO motifs in the C-terminus of putative ChR1s from green algae. Additionally, the study demonstrated the potential role of SUMOylation in modulating ChR1 protein in Chlamydomonas.

Summary: Fruit species are important for nutrition and health security as they provide micronutrients, antioxidants, and bioactive phytoconstituents, making fruit-based products functional foods for the present and future. Conventional breeding methods have improved fruit quality, aroma, antioxidants, yield, and nutritional traits, but climate change and other challenges require novel strategies. Biotechnological research in fruit crops offers opportunities for large-scale multiplication of elite clones, in vitro, mutagenesis, and genetic transformation. Advanced molecular methods, such as GWAS and genomic selection, are paving the way for trait-based improvement in fruit plant species for enhanced nutritional quality and agronomic performance.
