Heat stress has emerged as a critical threat, accelerating wheat growth, leading to premature maturation, reduced grain filling, and ultimately lower yields. The situation is exacerbated by more frequent and intense heat waves, particularly in regions already struggling with water scarcity. Maintaining the delicate balance of temperature and water necessary for optimal wheat production is becoming challenging, posing a serious risk to global food security. Therefore, there is an urgent need to develop adaptive strategies with innovations in breeding and transgenic technologies crucial to improving wheat resilience to environmental stresses, especially to combat the growing impacts of heat stress. Modern tools like CRISPR/Cas9, Transcription Activator-Like Effector Nucleases, and Zinc Finger Nucleases have been instrumental in developing wheat varieties with improved traits. However, the future of wheat cultivation requires more than just resistance to a single stressor. As climate change intensifies, there is an urgent need for wheat varieties that can withstand multiple stresses, including heat, drought, and pests. Developing these multi-stress-tolerant cultivars is crucial for ensuring food security in a rapidly changing climate.</p>","PeriodicalId":20064,"journal":{"name":"Plant Molecular Biology","volume":"115 2","pages":"41"},"PeriodicalIF":3.9,"publicationDate":"2025-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143586684","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Auxin is essential for root development in plants. Rice auxin response factor7 (OsARF7), belonging to the ARF family, is a key regulator of root development. Here, we show that OsARF7 positively regulates root development via auxin signaling. The osarf7 mutants display a significant decrease in the root number, adventitious root (AR) number and length, and primary root (PR) length, compared with the wild-type. Exogenous NAA treatment significantly suppresses PR length in osarf7 mutants, OsARF7-OE lines, and its wild-type, does not affect the root number of osarf7 mutants, but suppresses the biomass of osarf7 mutants. At the molecular level, OsARF7 is preferentially expressed in the culm, root, and leaf, especially highly expressed in the tips of the PR, AR, root pericycle, and lateral root (LR) primordia; meanwhile, OsARF7 expression is significantly enhanced by exogenous NAA treatment, suggesting that the positive regulatory role of OsARF7 on root development is based on auxin signaling. A series of biochemical and genetic analyses demonstrate that OsARF7 functions upstream of OsCRL1 and acts downstream of OsMADS25 to regulate root development via auxin signaling. To conclude, OsARF7 is a key positive regulatory factor that regulates root development by activating the expression of OsCRL1 via auxin signaling, by which, OsMADS25 positively mediates OsARF7 expression in rice.

In this study, a biosensor based on the Förster resonance energy transfer (FRET) of fluorescence dyes that can lead to the hybridization of oligonucleotide probes labeled with such dyes by using an excitation wavelength has been used to simultaneously measure microRNAs. Three microRNA compounds, i.e., miRNA-164, miRNA-167, and miRNA-399a, which play significant roles in the postharvest characteristics of strawberry fruits were measured. The simultaneous measurement was performed using three fluorescence dyes which exert various emission wavelengths at 570, 596, and 670 nm.

Rapeseed and mustard are cultivated worldwide and contribute significantly to the world's total oilseed production. Already a plateau is reached in terms of area and yield in most of the existing cultivars. Most of the commercially cultivated high yielding rapeseed and mustard varieties are tall, mainly due to a wider use of heterosis. However, they are susceptible to lodging and consequent yield losses. Plant yield is strongly dependent upon its architecture; therefore, 'ideotype breeding' is the key approach adopted to develop new varieties with enhanced yield potential, which is less explored in these crops. Dwarf/ semi dwarf plant type varieties has shown its improved yield potential over tall plant type in cereals which further leads to 'Green revolution' in Asian countries. Although, many induced dwarf mutants in rapeseed and mustard were isolated, unlike dwarf green-revolution varieties of cereals, most of them had undesirable plant types with defects including extreme dwarfism and sterility, leading to poor yield potential. Understanding the genetic and molecular mechanisms governing plant height and its correlation with yield and yield contributing characters is crucial. In this review, recent insights into genetic, molecular, and anatomical regulation of plant height have been discussed. The role of hormones, their crosstalk, and hormonal control for cell division and expansion have been delineated with respect to plant architecture. Many dwarfing genes are identified as being part of various phytohormone pathways. Parallelly, molecular links between plant height and flowering time have been explored.
