Sugar homeostasis is a critical feature of biological systems. In humans, raised and dysregulated blood sugar serious health issue. plants, directed changes in sucrose allocation represent opportunities crop improvement. Plant tissue varies more than glucose found at higher concentrations (cytosol phloem ca. 100 mM v 3.9-6.9 for glucose). Tissue with developmental stage environment, but cytosol exhibit tight control. Sucrose consequence the integration photosynthesis, synthesis storage end-products such as starch, transport to sinks sink metabolism. Trehalose 6-phosphate (T6P)-SnRK1 TOR play central, still emerging roles regulating coordinating these processes. Overall, levels are strongly related growth photosynthesis. As key signal, T6P regulates levels, metabolic pathways coordinate source whole plant level. Emerging evidence shows that interacts meristems. With careful targeting, manipulation through exploiting natural variation, chemical intervention genetic modification delivering benefits yields. Regulation cereal grain set, filling retention may be most strategically important aspect food security.

Summary Drought, especially terminal drought, severely limits wheat growth and yield. Understanding the complex mechanisms behind drought response in is essential for developing drought‐resistant varieties. This study aimed to dissect genetic architecture high‐yielding ideotypes under drought. An automated high‐throughput phenotyping platform was used examine 28 392 image‐based digital traits (i‐traits) different conditions during flowering stage of a natural population. Of i‐traits examined, 17 073 were identified as drought‐related. A genome‐wide association (GWAS) 5320 drought‐related significant single‐nucleotide polymorphisms (SNPs) 27 SNP clusters. notable hotspot region controlling tolerance discovered, which TaPP2C6 shown be an important negative regulator response. The tapp2c6 knockout lines exhibited enhanced resistance without yield penalty. haplotype analysis revealed favored allele that significantly correlated with resistance, affirming its potential value breeding programs. We developed advanced prediction model using 24 analyzed by machine learning. In summary, this provides comprehensive insights into ideotype approach rapid wheat.

Abstract Sugar signaling is one of the most critical regulatory signals in plants, and its metabolic network contains multiple factors. signal molecules regulate cellular activities organism development by combining with other intrinsic factors environmental inputs. HXK, SnRK1, TOR are three fundamental proteins that have a pivotal role metabolism sugars plants. being initial glucose sensor discovered renowned for multifaceted characteristics. Recent investigations unveiled HXK additionally assumes significant plant hormonal abiotic stress. SnRK1 serves as vital regulator growth under energy-depleted circumstances, whereas TOR, large protein, acts central integrator pathways govern cell metabolism, organ development, transcriptome reprogramming response to diverse stimuli. Together, these two work sense upstream modulate downstream proliferation. In recent years, there has been an increasing amount research on proteins, particularly SnRK1. Furthermore, studies found not only sugar but also exhibit certain crosstalk regulating development. This review provides comprehensive overview summary basic functions networks proteins. It aims serve reference further exploration interactions between their involvement co-regulatory networks.

The growth of yield outputs is dwindling after the first green revolution, which cannot meet demand for projected population increase by mid-century, especially with constant threat from extreme climates. Cereal requires carbon (C) assimilation in source subsequent allocation and utilization sink. However, whether or sink limits improvement, a crucial question strategic orientation future breeding cultivation, still under debate. To narrow knowledge gap capture progress, we focus on maize, rice, wheat briefly reviewing recent advances improvement modulation i) leaf photosynthesis; ii) primary C allocation, phloem loading, unloading; iii) grain storage; iv) systemic sugar signals (e.g., trehalose 6-phosphate). We highlight strategies optimizing to coordinate source-sink relationships promote yields. Finally, based understanding these physiological mechanisms, envisage scenery "smart crop" consisting flexible coordination plant economy, goal resilience field cereals crops.

Abstract Bread wheat ( Triticum aestivum ) is an important crop and serves as a significant source of protein calories for humans, worldwide. Nevertheless, its large allopolyploid genome poses constraints on genetic improvement. The complex reticulate evolutionary history the intricacy genomic resources make deciphering functional considerably more challenging. Recently, we have developed comprehensive list versatile computational tools with integration statistical models dissecting polyploid genome. Here, summarize methodological innovations applications these databases. A series step-by-step examples illustrates how can be utilized germplasm unveiling genes associated agronomic traits. Furthermore, outline future perspectives new advanced databases, taking into consideration unique features bread wheat, to accelerate genomic-assisted breeding.

Trehalose, trehalose-6-phosphate synthase (TPS),and trehalose-6-phosphatase (TPP) have been reported to play important roles in plant abiotic stress and growth development. However, their functions the flowering process of Rosa hybrida not characterized. In this study we found that, under a short photoperiod or weak light intensity, content trehalose shoot apical meristem cv ‘Carola’ significantly decreased, leading delayed time. A total nine RhTPSs seven RhTPPs genes were identified genome. Cis-element analysis suggested that RhTPS RhTPP involved hormones environmental responses. Transcriptome data reveals significant differences expression levels family different tissues indicates RhTPPF RhTPPJ are potential key rose flower bud development environments. The results quantitative real-time reverse transcription (qRT-PCR) further indicate intensity all members down-regulated. Additionally, RhTPS1a, RhTPS10, RhTPS11 up-regulated showed negative correlation with time decrease. Under was negatively regulated flowering, while RhTPS5, RhTPS6, RhTPS7b, RhTPS9, RhTPS10 down-regulated positively flowering. This work lays foundation for revealing gene families regulation trehalose.
