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

Cell wall remodeling involves the selective degradation of certain cell wall components or the integration of new components. Recently, accumulating evidence has underscored the importance of cell wall remodeling in plant regeneration. Wounding signals, transmitted by transcription factors, trigger the expressions of genes responsible for cell wall loosening, which is essential for tissue repair. In <i>de novo</i> organ regeneration and somatic embryogenesis, phytohormones orchestrate a transcriptional regulatory network to induce cell wall remodeling, which promotes cell fate reprogramming and organ formation.

The processes of grain filling and endosperm development are crucial for the accumulation of major storage compounds in rice grains. This requires extensive remobilization of carbon reserves from source to sink and the precise regulation of sucrose-to-starch conversion. Both the developmental sequence of the panicle and environmental signals influence the carbon flow between the leaves, leaf sheath, stem, and spikelets during grain filling. This, in turn, affects endosperm development and the production of storage compounds. In this review, we synthesize recent insight into grain development in rice, focusing on the dynamic changes in phytohormones and how their homeostasis integrates developmental and environmental cues to control grain filling in the developing panicle. We also highlight recent advances in the genetic control of carbohydrate remobilization and the transcriptional regulatory networks governing carbohydrate metabolism and grain development in rice. The asynchronous initiation and imbalance in grain filling limit the full yield potential of cereal crops. The “superior/inferior spikelets” serve as a model system for understanding the regulatory mechanisms underlying grain filling and development. Systematic research on carbohydrate flow and phytohormone crosstalk could enhance our understanding of optimizing yield production in cereal crops. Additionally, a thorough analysis of key genetic regulatory mechanisms can offer a genetic foundation and targets for precisely adjusting grain filling traits, ultimately aiding in the development of high-yield crop varieties.</p>","PeriodicalId":195,"journal":{"name":"Journal of Integrative Plant Biology","volume":"67 4","pages":"1086-1104"},"PeriodicalIF":9.3,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jipb.13904","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143794277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is the process by which plants, algae, and certain bacteria convert light energy into chemical energy. Through photosynthesis, solar energy is used to transform carbon dioxide and water into organic matter (such as glucose) and oxygen. This process not only provides energy and growth materials for plants themselves, but also supplies food and oxygen for other organisms in the ecosystems. The organic matter accumulated by crops through photosynthesis is the primary source of food for humans and animals. Improving photosynthetic efficiency can directly increase crop yields, helping to address the pressure of global population growth on food demand. Photosynthesis is also a core component of the Earth's carbon cycle, helping to maintain the balance of carbon dioxide and oxygen in the atmosphere and mitigating the effects of the greenhouse effect. Research on photosynthesis has also inspired the development of renewable energy. By mimicking the mechanisms of photosynthesis to design artificial photosynthetic systems, solar energy can be converted into clean energy for human beings. Focusing on photosynthesis research can help solve human challenges related to food, energy, and the environment. In recent years, extensive research has been conducted on the essence of energy absorption, transfer, and conversion in photosynthesis, yielding fruitful results.

(2025)&lt;/span&gt; commented on this research, noting that these MYB transcription factors not only regulate chloroplast development but also influence the expression of genes related to photosynthesis, photorespiration, and carbon fixation. Although MYB and GLK have synergistic roles in chloroplast biogenesis, MYB cannot fully replace GLK's functions. The commentary also pointed out that MYB transcription factors play a significant role in the development of male reproductive organs in plants. Future research should further explore the epigenetic regulation of MYB genes and their roles in stress responses, providing new insight for improving crop photosynthetic efficiency and yield.

However, the molecular mechanisms involved in rice PT growth and development remain largely unknown. In a previous study, microarray transcriptome analysis identified 627 genes preferentially expressed in the tricellular and germinating pollen of rice (i.e., Oryza sativa ssp. japonica). To elucidate key genes involved in the gene transfer process facilitated by male gametophytes, we systematically screened T-DNA lines containing disrupted sequences that corresponded to these 627 genes and analyzed the genotypes of heterozygote progeny from 107 T-DNA-indexed lines covering 105 genes. We found that 42 lines exhibited a distorted segregation ratio among the wild-type (WT), heterozygote (HT), and homozygote (HM) genotypes, which deviated from the expected Mendelian ratio of 1:2:1 (WT:HT:HM). Further characterization using CRISPR/Cas9 mutants revealed that knockout mutants of certain genes that exhibited segregation distortion in the T-DNA insertion region were completely sterile. Moreover, even when T-DNA insertion lines followed Mendelian segregation patterns, sterility could be induced by simultaneously mutating functionally redundant genes, thereby overcoming genetic compensation. Interestingly, although some T-DNA insertion lines exhibited segregation ratios approximating 1:1:0, the corresponding CRISPR/Cas9 mutants produced homozygous seeds and showed partial sterility. Partial sterility suggests that despite mutant pollen grains being less competitive than WT pollen, they retain their fertilization potential under relaxed competition from WT pollen. Beyond mutant-based analysis, transcriptomic profiling of sterile mutant lines provided additional insight into the regulatory relationship between key germination regulators and the 105 target genes studied here. Overall, this study demonstrates the effectiveness of a multi-pronged strategy to accelerate the identification of defective phenotypes using mutant studies and provides valuable genetic resources for inducing novel male sterility in rice.</p>","PeriodicalId":195,"journal":{"name":"Journal of Integrative Plant Biology","volume":" ","pages":""},"PeriodicalIF":9.3,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143750195","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
