Special Issue Information

Dear Colleagues,

Changes in cellular redox homeostasis affect plant growth and development and play a key role in plant stress management. Elimination of reactive oxygen and nitrogen species (ROS and RNS) produced by either environmental stress conditions or during the growth and developmental processes (internal stresses) occurs primarily through the ascorbate–glutathione pathway. However, melatonin, being at the heart of the redox network, is involved in the regulation of various molecular, biochemical, cellular, and physiological responses. Growth and development, as well as stress mitigation in plants, are redox regulated due to the cooperation between the cellular redox signaling and phytohormone signaling networks. Treatments affecting the redox state of the plant, such as exogenous application of melatonin, various antioxidants, or other chemicals, may act on stress mitigation, causing various biochemical and physiological and even gene regulatory changes. Their application therefore has great potential in alleviating and managing plant stress, even in the field.

This Special Issue, “Redox Regulation of Plant Growth and Development”, welcomes original research articles, reviews, and communications on antioxidant regulation of plant development and stress mitigation at different levels of research, such as gene expression, epigenetics, biochemistry, and physiology.

High-temperature stress severely limits the cultivation and ornamental quality of herbaceous peony, especially in low-latitude regions. The objective of this study was to reveal the potential mechanism involved in regulation of jasmonates on herbaceous peony heat tolerance through crosstalk between phytohormones and the reactive oxygen species (ROS) scavenging system. The study found that exogenous methyl jasmonate (MeJA) significantly improved thermotolerance of the low-latitude cultivar ‘Hang Baishao’ by enhancing antioxidase activities and modulating endogenous phytohormone levels. The MeJA-treated group exhibited markedly higher ratios of MeJA to zeatin riboside (ZR), gibberellic acid (GA3), brassinolide (BR), and indole-3-acetic acid (IAA) compared with the control group; catalase (CAT) and superoxide dismutase (SOD) activities were significantly elevated relative to hydrogen peroxide (H2O2) content, with both ratios peaking at 36 h post-heat treatment. Transcriptomic results revealed that MeJA reshaped the expression of genes involved in jasmonic acid (JA) signaling and ROS scavenging, such as FAD4, MED25, and JAZ2 and CSD2/3, FSD1, and CAT3. Four modules including the hub genes CIPK5/6, WRKY19/40 and CYPs were identified from the weighted gene co-expression network analysis (WGCNA), which may be key players in coordinating JA signaling and antioxidant defense. This study demonstrates that MeJA enhanced herbaceous peony thermotolerance by orchestrating a regulatory network involving phytohormonal crosstalk and activation of the ROS scavenging system, and offers candidate genes for future exploration of function and interactions.

Flower senescence is a key physiological constraint on the ornamental and commercial longevity of cut roses. Although abscisic acid (ABA) is recognized as a promoter of this process, the molecular circuitry through which ABA operates, particularly the specific contributions of MYB transcription factors, remains largely unexplored. In this study, we identify RcMYB002 as a negative regulator of rose flower senescence. Transient overexpression of RcMYB002 significantly delays senescence, preserves anthocyanin accumulation, and modulates antioxidant enzyme activities in a time-dependent manner, consequently attenuating ABA-triggered oxidative stress. In contrast, silencing RcMYB002 accelerates senescence-associated phenotypes. At the molecular level, ABA suppresses RcMYB002 transcript accumulation, while yeast one-hybrid (Y1H) assays indicate that RcMYB002 interacts with the promoter regions of senescence-associated genes SAG12 and SAG21, consistent with a role in their transcriptional regulation. Taken together, our results support a model in which ABA promotes flower senescence by downregulating RcMYB002, thereby derepressing downstream senescence-executing genes. This work provides a molecular basis for understanding flower senescence and offers a potential target for extending rose vase life. Full article
