The KNOX (KNOTTED1-like homeobox gene) gene family plays a pivotal role in controlling plant growth, maturation, and morphogenesis. However, the function of Vitis amurensis has not yet been reported. This study identified characterized entire amurensis. By employing bioinformatic approaches, phylogenetic relationships, chromosomal positions, architectures, conserved motifs, cis-regulatory elements present promoter regions, expression profiles members were analyzed. Ten genes spanning nine chromosomes discovered, these subsequently categorized into two distinct subclasses. regions include cis-acting that are involved hormonal regulation, stress light responses. An examination different tissues revealed Class I presented tissue-specific patterns, whereas belonging to II more ubiquitous across various tissues. levels KNOTTED1-like (VaKNOX)2, VaKNOX3, VaKNOX5 highest fruits. VaKNOX2, can serve as candidate for enhancing fruit quality. VaKNOX6 VaKNOX7 much higher cold environments than normal conditions. Through in-depth research functions VaKNOX7, we aimed improve resistance grapevine varieties.

Опубликована: Апрель 9, 2025

ABSTRACT Production of high‐yield and high‐quality fruits is always the long‐term objective fruit crop cultivation, which, however, challenged by various abiotic stresses such as drought, extreme temperatures high salinity, adverse impacts on crops are exacerbated climate change in recent years. To cope with these environmental stressors, have evolved adaptative strategies involving physiological changes molecular regulation. In this review, we summarise relevent photosynthesis, osmotic reactive oxygen species (ROS) equilibrium, metabolism protein homeostasis response to stresses. Moreover, perception stimuli well progress underlying regulatory mechanisms also discussed. Based our current knowledge, possible for stress resilience improvement accordingly proposed. addition, discuss challenges identification key nodes plant responses multiple development stress‐resilient crops, addressing issues future would advance understanding how combat facilitate breeding superior that can adapt thrive changing environments.

An integrative overview of cold response and regulatory pathways in horticultural crops

Journal of Integrative Plant Biology, Год журнала: 2025, Номер unknown

Опубликована: Апрель 11, 2025

ABSTRACT Global climate change challenges agricultural production, as extreme temperature fluctuations negatively affect crop growth and yield. Low (LT) stress impedes photosynthesis, disrupts metabolic processes, compromises the integrity of cell membranes, ultimately resulting in diminished yield quality. Notably, many tropical or subtropical horticultural plants are particularly susceptible to LT stress. To address these challenges, it is imperative understand mechanisms underlying cold tolerance crops. This review summarizes recent advances physiological molecular that enable crops withstand stress, emphasizing discrepancies between model systems. These include C‐repeat binding factor‐dependent transcriptional regulation, post‐translational modifications, epigenetic control, regulation. Reactive oxygen species, plant hormones, light signaling pathways integrated into response network. Furthermore, technical for improving highlighted, including genetic improvement, application light‐emitting diodes, utility novel regulators, grafting. Finally, prospective directions fundamental research practical applications boost discussed.
