Summary: Impairment in OASTLA and OASTLB confers higher sensitivity to selenate in Arabidopsis, and OASTLA, B, and C act as l-Cys and l-SeCys desulfhydrases. The impaired OASTLA and OASTLB resulted in reduced biomass, chlorophyll and soluble protein content, indicating a futile anabolic S-starvation response and increased oxidative stress symptoms. In-gel assays revealed enhanced desulfhydrase activities in response to selenate in OASTLA and OASTLB mutants.

Summary: This study aims to analyze the interrelationship between nitric oxide (NO) and hydrogen sulfide (H2S) during pepper fruit ripening. The results show that the activity of H2S-generating enzymes LCD and DCD is downregulated during ripening, but it can be reversed by NO treatment. These findings enhance our understanding of the relationship between NO and H2S during pepper fruit ripening.

Summary: The study revealed variations in endogenous hydrogen sulfide (H2S) content and emission among different plants, with the highest levels found in Allium species. The activity of L-cysteine desulfhydrase (LCD) correlated positively with H2S content in plants, particularly in Allium species, suggesting potential health benefits associated with consuming these plants.

Summary: Temperature stress negatively affects fruit set and growth in tomatoes. The localization of auxin in the ovaries and peduncles, which affects fruit set and growth, is disturbed by short-term high-temperature stress. On the other hand, low-temperature stress does not significantly affect fruit set, but causes a delay and recovery of fruit growth.

Summary: The study revealed the important role of H2S-generating enzyme LCD1 in regulating leaf senescence in tomato. Overexpression of LCD1 delayed leaf senescence, while its deletion accelerated the process. The expression of LCD1 was correlated with chlorophyll degradation, ROS accumulation, and the expression of senescence-related genes, providing insight into the physiological functions of LCD1 in tomato leaf senescence.

Summary: This study reveals that hydrogen sulfide (H2S) plays an important role in alleviating manganese (Mn) stress in Arabidopsis. H2S reduces Mn content, decreases reactive oxygen species accumulation, and enhances antioxidant enzyme activity, thereby mitigating the inhibitory effect of Mn stress on Arabidopsis seedling growth.

Summary: The development of giant feeding cells induced by root-knot nematodes in tomato involves the extensive reprogramming of gene expression, and the auxin signal plays a crucial role in this process. This study identified two auxin-responsive transcription factors, ARF8A and ARF8B, and their miRNA167 regulators as potential candidates involved in the tomato response to Meloidogyne incognita. The expression analysis showed up-regulation of ARF8A and ARF8B in RKN-induced feeding cells and surrounding cells.

Summary: Studies have revealed the importance of DES in modulating H2S production, particularly in response to biotic and abiotic stress stimuli. Mutants of the model plant Arabidopsis thaliana have uncovered the molecular mechanisms of H2S as a signaling and defense molecule in plant-pathogen interactions. H2S signaling pathways, including S-persulfidation of protein cysteines, play a crucial role in activating downstream components of the H2S signaling pathway.

Summary: This study found that tomato brown rugose fruit virus (ToBRFV) significantly affects root development in tomato plants, leading to a decrease in root biomass, elongation, root-to-shoot ratio, and suppression of root branching. The study also identified the role of the plant gene SlARF10a in the ToBRFV-mediated suppression of root branching.

Summary: The study found that silicon absorption in tomato plants varies among different cultivars, with root concentrations significantly higher than leaves. Although some cultivars showed differences in other element concentrations in roots and leaves with silicon treatment, most macronutrients and micronutrients were unaffected.

Summary: This study examined root bifurcation in the lycophyte Selaginella moellendorffii and found that the initial cells in the root meristem are irregular in shape rather than tetrahedral as previously assumed. The study also identified a subset of core meristem genes and suggested the presence of conserved pathways in the control of meristem and root stem cell establishment or maintenance. These findings contribute to a better understanding of root formation and development in plants.

Summary: Roots play crucial roles in plant growth by anchoring and absorbing water and nutrients. Root evolution occurred independently at least twice in lycophyte and euphyllophyte clades, with the control mechanisms of root development in lycophytes remaining unclear.

Summary: This study investigated the effect of calcium chloride (CaCl2) treatment on GABA accumulation in fresh-cut cantaloupe and the underlying mechanisms. The results showed that CaCl2 treatment increased GABA content and the activities of GAD and SSADH enzymes, while reducing glutamate content and GABA-T activity. Additionally, CaCl2 treatment upregulated the expressions of CmCML11 and CmCAMTA5, as well as several GABA shunt genes, through the transcriptional activation by CmCAMTA5. Furthermore, the interaction between CmCML11 and CmCAMTA5 enhanced the transcriptional activation of GABA shunt genes. Overall, this study reveals that CaCl2 treatment promotes GABA accumulation in fresh-cut cantaloupe through the combined effect of CmCML11 and CmCAMTA5 in regulating the expressions of GABA shunt genes.

Summary: This study identified the high nitrogen use efficiency (NUE) black sesame variety 17-156 and analyzed its underlying physiological and molecular mechanisms. The results showed that 17-156 possesses a sophisticated nitrogen metabolizing machinery to uptake and assimilate higher quantities of inorganic nitrogen, simultaneously improving carbon metabolism and growth. Many important genes were up-regulated in 17-156 under high nitrogen condition. Additionally, 38 potential candidate genes were identified for future studies to improve sesame's NUE. These findings provide valuable resources for understanding the regulatory network of nitrogen metabolism and developing sesame cultivars with improved NUE.

Summary: This study cloned the full-length cDNA sequence of TaSPX3 gene in wheat and found that TaSPX3 responds to low phosphorus stress in multiple wheat genotypes. Overexpressing TaSPX3 can alleviate phosphorus deficiency symptoms and promote plant growth in Arabidopsis. The study also revealed the interaction of TaSPX3 with other genes related to the phosphorus starvation signaling pathway.

Summary: Selenium (Se) can reduce uptake and translocation of cadmium (Cd) in plants by regulating root morphology. This study investigated the effects of Se(IV) on root exudates, root morphology, root endogenous hormones, and Cd uptake efficiency in rice under Cd stress. The results showed that Se(IV) significantly reduced Cd concentrations in shoots and roots, and decreased Cd uptake efficiency via root hairs. Se(IV) also affected root morphology, root exudates, and the synthesis of hormones like IAA and JA. However, transcriptome analysis revealed no upregulated differentially expressed genes (DEGs) in IAA synthesis.
