Cotton's fundamental requirements for long periods of growth and specific seasonal temperatures limit the global arable areas that can be utilized to cultivate cotton. This constraint alleviated by breeding early-maturing varieties. By delaying sowing dates without impacting boll-opening time, varieties not only mitigate yield losses brought on unfavorable weathers in early spring late autumn but also help reducing competition between cotton other crops land, thereby optimizing cropping system. review presents studies efforts cotton, which efficiently pyramid maturity, high-quality, multiresistance traits, suitable plant architecture leveraging pleiotropic genes. Attempts are made summarize our current understanding molecular mechanisms underlying maturation, involves many pathways such as epigenetic, circadian clock, hormone signaling pathways. Moreover, new avenues effective measures proposed fine-scale ensure healthy development agricultural industry.

Abstract Background The brown planthopper (BPH) is a kind of piercing-sucking insect specific to rice, with the damage tops list pathogens and insects in recent years. microRNAs (miRNAs) are pivotal regulators plant–environment interactions, while mechanism underlying their function against largely unknown. Results Here, we confirmed that OsmiR319, an ancient conserved miRNA, negatively regulated resistance BPHs, overexpression OsmiR319 susceptible BPH, suppression resistant BPH comparison wild type. Meanwhile, identified several targets may mediate resistance. Among them, OsPCF5 was most obviously induced by feeding, over expression BPH. In addition, various biochemical assays verified interacted MYB proteins, such as OsMYB22, OsMYB30, OsMYB30C.Genetically, revealed both OsMYB22 OsMYB30C positively Genetic interaction analyses same genetic pathway OsmiR319b Conclusions Altogether, regulates via association proteins downstream these might through regulating phenylpropane synthesis.

Abstract Maintenance of intracellular ion balance, especially Na+ and K+, plays an important role in plant responses to salt stress. Vessels xylem are responsible for long-distance transport vascular plants. Knowledge on the stress response woody plants limited. In this study, we identified miR319a as regulator respond poplar. overexpression transgenic poplar showed a salt-tolerant phenotype, cytological observation reduced cambium cell layers, wider xylem, increased number lumen area vessels fibers, thinner wall thickness transgenics. The miR319a-MIMIC plants, meanwhile, had opposite phenotypes, with narrower fibers cells, thickness. addition, driven by vessel-specific promoter significantly improved tolerance compared fiber-specific promoter. expression levels PagHKT1;2 PagSKOR1-b, which encoded high-affinity K+ transporters efflux influx, respectively, were positively correlated vessel area. These results suggest that miR319 not only promotes rates increasing reducing thickness, but also regulates concentrations up-regulating PagSKOR1-b. We demonstrate may coordinate through both mechanisms, enriching our understanding synergistic effects secondary structure balance

The application of miRNA mimic technology for silencing mature began in 2007. This technique originated from the discovery INDUCED BY PHOSPHATE STARVATION 1 (IPS1) gene, which was found to be a competitive that prevents cleavage targeted mRNA by inhibition at post-transcriptional level. To date, various studies have been conducted understand molecular mechanism and improve efficiency this technology. As result, several tools developed: target mimicry (TM), short tandem (STTM), sponges (SPs). STTM is most-developed tool due its stability effectiveness decoying miRNA. review discusses on loss-of-function members diverse plant species. A modified approach studying function with spatial–temporal expression under control specific promoters further explored. will enhance our understanding activity plant-tissue-specific development stress responses applications improving traits via regulation.

Sessile plants engage in trade-offs between growth and defense capacity response to fluctuating environmental cues. MYB is an important transcription factor that plays many roles controlling plant defense. However, the mechanism behind how it keeps a balance these two physiological processes still largely unknown. Our work focuses on dissection of molecular by which GhMYB33 regulates The CRISPR/Cas9 technique was used generate mutants for deciphering functions. Yeast two-hybrid, luciferase complementary imaging, co-immunoprecipitation assays were prove proteins interact with each other. We electrophoretic mobility shift assay, yeast one-hybrid, activity analyze acting as promoter. A β-glucuronidase fusion reporter 5' RNA ligase mediated amplification cDNA ends analysis showed ghr-miR319c directedly cleaved mRNA. Overexpressing miR319c-resistant (rGhMYB33) promoted growth, accompanied significant decline resistance against Verticillium dahliae. Conversely, its knockout mutant, ghmyb33, demonstrated restriction concomitant augmentation V. dahliae resistance. found couple DELLA protein GhGAI1 bind specific cis-elements GhSPL9 GhDFR1 promoters, thereby modulating internode elongation infection. discovered target suppress expression. overexpression led enhanced simultaneous reduction height. findings demonstrate encodes hub controls expression GhDFR1, implicating pivotal role miR319c-MYB33 module regulate

Plant architecture is a crucial influencing factor of wheat yield and adaptation. In this study, we cloned characterized TaSPL14, homologous gene the rice ideal plant OsSPL14 in wheat. TaSPL14 homoeologs (TaSPL14-7A, TaSPL14-7B TaSPL14-7D) exhibited similar expression patterns, they were all preferentially expressed stems at elongation stage young spikes. Moreover, level TaSPL14-7A was higher than that TaSPL14-7D. Overexpression resulted significant changes traits, including decreased tiller number increased kernel size weight. Three haplotypes identified Chinese core collection, haplotype-based association analysis showed TaSPL14-7A-Hap1/2 significantly correlated with fewer tillers, larger kernels weights modern cultivars. The haplotype effect from difference levels among genotypes, leading to TaSPL14-7A-Hap3. As favorable haplotypes, underwent positive selection during global breeding over last century. Together, findings our study provide insight into function genetic effects useful molecular marker for breeding.

ABSTRACT IDEAL PLANT ARCHITECTURE1 (IPA1) is a pivotal gene controlling plant architecture and grain yield. However, little known about the effects of Triticum aestivum SQUAMOSA PROMOTER‐BINDING‐LIKE 14 (TaSPL14), an IPA1 ortholog in wheat, on balancing yield traits its regulatory mechanism wheat ( T. L.). Here, we determined that GRAIN WIDTH2 (TaGW2)‐TaSPL14 module influences balance between tiller number weight wheat. Overexpression TaSPL14 resulted reduced increased weight, whereas knockout had opposite effect, indicating negatively regulates tillering while positively regulating weight. We further identified TaGW2 as novel interacting protein confirmed ability to mediate ubiquitination degradation TaSPL14. Based our genetic evidence, acts positive regulator number, addition role negative which Moreover, combinations TaSPL14‐7A TaGW2‐6A haplotypes exhibit significantly additive breeding. Our findings provide insight into how TaGW2‐TaSPL14 trade‐off potential application improving
