Summary: This study conducted the first comprehensive genome-wide exploration of the PDI gene family in Rosa chinensis and revealed their role in flower aging. The researchers identified 41 RcPDIs in the genome of R. chinensis and investigated their chromosomal distribution, gene structure, and conserved protein sequences. Protein interaction analysis also showed that RhPDI and RhPDIA6 were related to other protein disulfide isomerases and oxidases. Additionally, the study found that the expression of both genes in cut roses can be induced by ethylene treatment.

Summary: In this study, we focused on the ethylene-responsive factor RhERF3 identified in ethylene-treated rose flowers, and found that RhERF3 expression is strongly induced by ethylene during rose flower senescence. Transient silencing and overexpression of RhERF3 revealed its role in regulating the process of rose flower senescence. RNA sequencing analysis showed that RhERF3 is mainly related to metabolic processes and plant hormone signal transduction pathways.

Summary: Wound healing is a complex process requiring adequate blood supply of oxygen and nutrients. Lack of blood supply can result in chronic wounds. This study aimed to develop a new wound healing model for ischemic wounds using chick chorioallantoic membrane (CAM) integrated split skin grafts and induction of ischemia with photo-activated Rose Bengal (RB). The study showed a significant reduction in blood flow and development of chronic wounds in the selected area using RB.

Summary: Recent studies have shown that the interaction between immune and metabolic responses is crucial for maintaining tissue and organ homeostasis, playing a significant role in the development of chronic diseases. In diabetic wound healing, the abnormal activation of innate immune cells is essential in triggering and sustaining inflammation. Targeting these innate immune pathways and reprogramming immune cell phenotypes show great potential in diabetic wound therapy.

Summary: Following successful pollination, Dendrobium orchid flowers undergo rapid senescence. Compatible pollination results in faster ethylene production and more rapid development of senescence symptoms compared with non-pollinated or incompatible pollinated flowers. Pollination with compatible pollinia leads to higher expression of DenACS1 and DenACO1 genes. Incompatible pollinia reduce the expression of DenACS1 and DenACO1 genes in the perianth. DenERS1, DenEIL1, and DenERF1 genes show differential spatial regulation following compatible pollination. Compatible pollinia increase ethylene production, induce premature senescence, and suppress DenERS1 expression, while incompatible pollinia do not stimulate ethylene production or induce senescence but lead to higher DenERS1 expression in both the perianth and the column plus ovary.

Summary: Skin, as the largest organ of the body, is compromised with time due to intrinsic and extrinsic ageing processes, primarily at the cellular level through cellular senescence. While evidence suggests that cellular senescence is a relevant cause of intrinsic skin ageing, it is not yet completely conclusive.

Summary: The study has demonstrated that WRKY71 acts as a positive regulator of leaf senescence in Arabidopsis, directly regulating senescence-associated genes and mediating multiple signals to accelerate leaf senescence. Additionally, WRKY71 was found to mediate ethylene signaling and synthesis, providing new insights into the molecular mechanisms of leaf senescence regulation.

Summary: Ethylene plays a crucial role in regulating senescence in ethylene sensitive flowers, while having little to no impact on ethylene insensitive flowers. Various growth regulators inhibit ethylene biosynthesis or perception, essential for regulating important developmental processes in plants.

Summary: This study investigated the expression levels of senescence-associated genes and ethylene-related genes in cabbage, broccoli, and kale during postharvest storage at different temperatures. The results showed that gene expression was closely linked to storage temperature and senescence phase, with reduced variation in expression levels of some genes under prolonged cold storage, suggesting a delay in the senescence mechanism. The findings contribute to understanding the molecular events associated with senescence in Brassica vegetables and could potentially improve postharvest storage practices.

Summary: The study focused on the impact of ethylene on nitrogen mobilization during leaf senescence in grapevines, revealing significant changes in metabolomic processes and amino acid composition, leading to a decrease in leaf nitrogen content. This offers potential for targeted induction of senescence and improvement in nitrogen supply for grapes through ethylene treatment.
