While it has been thoroughly studied in leaves, its dynamics in fruits have not been adequately explored. This research gap is significant, as the cuticle in fruits has considerable implications for crop quality, postharvest longevity, and stress resilience. This review summarizes current understanding of cuticular dynamics during the development of fleshy fruits, with a focus on evolutionary innovations that have influenced cuticle diversity in angiosperms. We explore the conserved yet highly regulated biosynthetic pathways, emphasizing compositional variations in cutin and cuticular wax specific to different species and developmental stages. The review outlines how transcriptional, hormonal, and epigenetic networks regulate cuticle formation in response to both biotic/abiotic stress, and how these changes influence fruit quality traits such as glossiness, firmness, and susceptibility to cracking. We discuss the potential of targeting cuticular genes-through breeding, transgenic methods, or CRISPR-Cas9 editing-to improve stress tolerance and fruit quality. This work highlights the importance of the cuticle in improving agricultural sustainability, especially in response to climate change, by integrating fundamental insights from model plants with applied research in fruit crops. We propose that fruit-focused research should leverage cuticle biology to develop resilient, high-quality varieties. This approach aims to reduce postharvest losses and enhance food security.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s12298-026-01784-6.</p>","PeriodicalId":20148,"journal":{"name":"Physiology and Molecular Biology of Plants","volume":"32 8","pages":"1671-1685"},"PeriodicalIF":3.6,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13438044/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148679686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current review focuses on key molecular mechanisms, including transcriptional factors and expression of stress-responsive genes, production of mitochondrial reactive oxygen species, modulation of signaling molecules, and circadian rhythm-mediated defense responses during onset of drought stress in vegetable crops. Further, plant-based mitigation strategies, such as use of phytomolecules, phytohormones, plant extracts, microbial endophytes, and drought-tolerant rootstocks from crop wild species for grafting onto vegetable crops are discussed for their role in enhancing drought resilience. Also, combining these strategies strengthens the antioxidant defense mechanism, osmotic homeostasis, and hormonal crosstalk under drought stress. Among the various strategies reported, phytomolecules, microbial endophytes, and drought-tolerant rootstocks from crop wild relatives are found to be promising for long-term field adaptations.

The biosynthesis and degradation of CTKs are primarily governed by the isopentenyl transferase (IPT) and cytokinin oxidase/dehydrogenase (CKX) gene families, respectively. However, a comprehensive analysis of both gene families in oat (<i>Avena sativa</i>) has not yet been performed. Here, we characterized the <i>AsCKX</i> and <i>AsIPT</i> genes and their encoded proteins. Additionally, we determined the levels of 6 types of endogenous CTKs, and the expression patterns of all <i>AsCKX</i> and <i>AsIPT</i> genes under alkaline and osmotic stresses. Our results showed that <i>AsCKX</i> and <i>AsIPT</i> genes exhibit diverse physicochemical properties and specific secondary and tertiary structures. Phylogenetic and synteny analyses revealed that these genes share high homology with homologs in the rice. Multiple segmental duplication events were identified both within the oat genome and between oat and other species, with clear evidence of positive selection for adaptation to abiotic stresses. Meanwhile, these genes contain various cis-acting elements associated with abiotic stresses. Expression pattern analysis indicated that, at 6 h under both alkaline and osmotic stresses, oats may respond to the stress by upregulating <i>AsCKX</i> and downregulating <i>AsIPT</i> genes to reduce the CTK content. With the prolongation of stress duration, differential changes were observed in <i>AsCKX</i> and <i>AsIPT</i> genes between two types of stresses. Interestingly, <i>AsCKX12</i> was identified as a negative regulator during osmotic stress response.

To address this gap, we investigated the physiological performance of the model cyanobacterium <i>Synechococcus elongatus</i> PCC 7942 under UVR exposure. Employing Pulse Amplitude Modulation (PAM) fluorometry, a non-invasive technique, we assessed the photochemical efficiency of Photosystem II (PSII). Our data not only corroborate previous findings but also provide novel insights into the potential of UVR to enhance photosynthetic electron transport rates in <i>Synechococcus elongatus</i> PCC 7942. This study examined the combined effects of photosynthetically active radiation (PAR; 400-700 nm) and UVR on the growth and various physiological parameters of this cyanobacterium. Notably, while PAR + UVR negatively influenced growth, it did not compromise overall fitness. The observed enhancement in carotenoid production, modulation of pigment ratios, and maintenance of cellular morphology suggest the activation of acclimatization mechanisms in response to the combined light stress. Despite initial declines in photosynthetic performance, the remarkable recovery and resilience of <i>Synechococcus elongatus</i> PCC 7942 over time underscore its robustness. Consequently, these findings illuminate the resistance mechanisms of this commercially important cyanobacterium to changing light environments, highlighting the dual role of UVR as both an environmental stressor and a trigger for protective physiological responses.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s12298-026-01797-1.</p>","PeriodicalId":20148,"journal":{"name":"Physiology and Molecular Biology of Plants","volume":"32 8","pages":"1901-1918"},"PeriodicalIF":3.6,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13437837/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148679620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Relative water content and electrolyte leakage was also adjusted to optimum level under stressed plant when sprayed with Si and SA. Explicitly, Si and SA enhanced proline content and superoxide dismutase activity, reduced the toxicity due to reactive oxygen species, and improved the membrane stability during stress conditions. Compared to SA, Si was more responsive in regulation of both class of Tonoplast intrinsic protein and Nodulin 26-like intrinsic protein aquaporins genes in poplar during stress conditions.
