Litchi seed development is a fascinating process because of its remarkable plasticity. Previous study has indicated that the partial seed abortion phenotype of litchi cv. ‘Guiwei’ is induced by thermo-sensitive sterility and self-sterility. The comprehension of how genetic background and temperature influence the litchi seed development is limited. Here, we target <em>LcASHR1</em>, a putative histone-lysine N-methyltransferase gene, and <em>LcEMF2</em>, an EMBRYONIC FLOWER 2 gene, that were shown to be more highly expressed in the large seed cultivar ‘Huaizhi’ than in the small seed cultivar ‘Guiwei’. In addition, they were found to be enhanced in response to low temperatures, a condition flavoring the seed development of ‘Guiwei’ seeds. Among them, only the knockdown of <em>LcASHR1</em> in litchi resulted in tiny seeds and a higher level of seed abortion rate. Conversely, overexpression of <em>LcASHR1</em> in <em>Arabidopsis</em> lines led to the production of larger seeds. Furthermore, LcTRB1, a putative telomere repeats binding protein, was identified as a upstream transact factor of <em>LcASHR1</em> by binding to the telo-boxes in the promoter. <em>LcTRB1</em> expression pattern largely corresponded to litchi seed size. Consistent with previous findings on <em>LcASHR1</em>, it has been observed that <em>LcTRB</em>1 positively affects seed development in both litchi and arabidopsis. Overall, our results indicated that LcTRB1 is linked with litchi seed development probably by modulating the expression of <em>LcASHR1</em>.</div></div>","PeriodicalId":34736,"journal":{"name":"Plant Stress","volume":"15 ","pages":"Article 100745"},"PeriodicalIF":6.8,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143098392","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study aimed to examine the effect of leaf-applied trehalose (Tre) on ion homeostasis, photosynthesis, antioxidant defense mechanisms, osmolyte accumulation, cell viability, oxidative stress biomarkers, and histo-microscopical analyses in Indian mustard under NaCl stress. Sodium chloride stress drastically decreased growth, water status, protein content and net photosynthetic rate, while increasing lipid peroxidation, ion toxicity, cell death, and electrolyte leakage due to the excessive accumulation of reactive oxygen species (ROS) in Indian mustard. Foliar fertigation of Tre significantly increased growth traits, nutrient acquisition, chlorophyll content, osmolyte accumulation, protein content, antioxidant enzyme activities, stomatal aperture, and cell viability, while considerably reducing leaf Na<sup>+</sup> content and NaCl-generated ROS toxicity in Indian mustard. The Tre application enhanced shoot dry weight by 16 %, net photosynthetic rate by 19.37 %, superoxide dismutase activity by 10 %, nitrogen content by 13.32 %, seed yield by 23 % and oil yield by 27 %, while decreased superoxide anion content by 26 %, sodium ion content by 14.47 % and malondialdehyde content by 11.41 % over 0 mM NaCl treatment. Moreover, the trehalose-mediated reduction in ROS production was further validated with histochemical and microscopical localization analyses.

Understanding photosynthetic apparatus's response to harsh environmental conditions and evaluating antioxidative levels is essential since it can reveal the mechanisms of their stress tolerance and the strategies for enhancing cold and freezing tolerance. This study examines how cold and freezing temperatures impact photosynthetic activity, chlorophyll fluorescence, total flavonoid and phenol content, antioxidant capacity, as well as the levels of photosynthetic and stress-induced proteins in Ramonda species leaves during autumn and winter in the natural condition. Based on the results obtained, the greatest reduction in CO<sub>2</sub> assimilation occurred during freezing stress in comparison to both cold stress and control conditions. The quantum efficiency of photosystem II was slightly affected during cold temperatures but gradually decreased when the temperatures dropped to freezing, reaching minimum values in the desiccated leaves. Significant enhancement in the total phenolic and flavonoid content, as well as increased antioxidant capacity in both Ramonda species during desiccation under freezing stress, helps to protect plants against oxidative damage. Low temperatures decreased the abundance of fundamental photosynthetic proteins, whereas the content of some light-harvesting complex (LHC) proteins was increased. The accumulation of early light-inducible proteins (ELIPs) and dehydrins suggested their role in the acquisition of freezing tolerance. The results show that Ramonda species have developed some biochemical and physiological adaptations that enhance their ability to preserve their photosynthetic processes during cold and freezing temperatures. Findings from this study may contribute to the development of breeding strategies in agriculture, particularly for cold-prone regions, to enhance crop resilience and productivity under challenging environmental conditions.</div></div>","PeriodicalId":34736,"journal":{"name":"Plant Stress","volume":"15 ","pages":"Article 100741"},"PeriodicalIF":6.8,"publicationDate":"2025-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143098826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For example, it has been shown that the transcriptional responses to drought can be “trained”, i.e. changed, by a previous stress episode. Also, the so-called after-effect of drought is a feature of stress memory seen at the stomatal level: an incomplete recovery of conductance after drought, even when water potential has fully recovered. This effect has been shown to depend on the phytohormones abscisic acid and strigolactones, but whether and how repeated drought spells affect its intensity is unclear, as it is unclear how much of the “trainability” of physiological and molecular responses depends on strigolactones. This study investigated the contribution of strigolactones to physiological and transcriptional drought memory, by comparing the stomatal conductance and transcriptome of wild-type versus strigolactone-depleted tomato plants in repeated dehydration cycles. We found that the after-effect of drought can be primed by a previous drought episode; and, that strigolactones are indispensable for full priming. About half of the genes that display a drought memory profile require an intact strigolactone pathway for trainability. Several potential candidates are proposed as effectors of strigolactone-dependent drought memory, namely for enhanced abscisic acid sensitivity and antioxidant activities, and for the maintenance of cellular homeostasis via enhanced protein preservation under environmental duress.

The common consensus is that currently, studies on phenotypic and transcriptomics analysis are prevailing, while metabolic studies are scarce. Despite the need for further studies to validate the findings in this review, two clear biological messages emerge. First, and perhaps unsurprisingly, proline stands out as a universal stress metabolite, closely followed by branched-chain amino acids. Interestingly, while multifactorial stress responses are often considered non-additive and unpredictable, our findings reveal that many metabolic changes are both. Expanding the scope of studies to include more species and a wider range of stresses at the metabolic level will be essential for uncovering additional metabolic reprogramming in response to multifactorial stress.

This review synthesizes current studies on the impact of drought and herbivore defense mechanisms and associated metabolic changes in plants. Severe drought can enhance plant tolerance to herbivores by promoting escape strategies whereas mild or intermittent drought may benefit insects by increasing nutrient availability. We discuss how plants adjust their metabolism to mitigate the effects of combined stresses. We further highlight the role of hormonal signaling pathways, such as abscisic acid, jasmonic acid, salicylic acid and ethylene in coordinating plant responses. Research on metabolic changes accompanying hormonal crosstalk involved in managing multiple stresses is still emerging. The available evidence suggests that the outcome of drought and herbivory varies depending on factors such as stress intensity, duration, plant-herbivore species, and insect-feeding guilds.
