Abstract Background Chlorophyll (Chl) is an agronomic trait associated with photosynthesis and yield. Gibberellin 2-oxidases (GA2oxs) have previously been shown to be involved in Chl accumulation. However, whether how the PbrGA2ox proteins (PbrGA2oxs) mediate accumulation pear ( Pyrus spp. ) scarce. Results Here, we aimed elucidate role of GA2ox gene family related underlying mechanisms. We isolated 13 genes PbrGA2oxs from database identified PbrGA2ox1 as a potential regulator found that transiently overexpressing chlorotic leaves led accumulation, silencing normal degradation, evident by regreening chlorosis phenomenon, respectively. Meanwhile, -overexpressing (OE) tobacco plants discernably exhibited built-up, evidenced significantly higher Pn Fv / Fm . In addition, RNA sequencing (RNA-seq), physiological biochemical investigations revealed increase abscisic acid (ABA), methyl jasmonate (MeJA), salicylic (SA) concentrations signaling pathways; marked elevation reducing soluble sugar contents; marginal decline starch sucrose levels OE plants. Interestingly, overexpression did not prominently affect synthesis. it indeed facilitated chloroplast development increasing number per cell compacting thylakoid granum stacks. These findings might jointly contribute Conclusion Overall, our results suggested GA2oxs accelerate stimulating proved candidate for genetically breeding biofortified

Sand pear is the main cultivated species in China, and brown peel a unique feature of sand pear. The formation related to activity cork layer, which lignin an important component. intimately associated with biosynthesis accumulation lignin; however, regulatory mechanism remains unclear. In this study, we used newly bred cultivar 'Xinyu' as material investigate at nine developmental stages using metabolomic transcriptomic methods. Our results showed that 30 days after flowering (DAF) 50DAF were key periods according data analysis from assays measurement, scanning electron microscope (SEM) observation, metabolomics, transcriptomics. Through weighted gene co-expression network (WGCNA), positively correlated modules identified. A total difference components identified 148 differentially expressed genes (DEGs), including 10 structural (PAL1, C4H, two 4CL genes, HCT, CSE, COMT CCR genes) MYB, NAC, ERF, TCP transcription factor involved metabolism. An RT-qPCR confirmed these DEGs regulation lignin. These findings further help us understand mechanisms provide theoretical basis for color control quality improvement breeding cultivation.

Fruit quality is one of the most important economic traits fruit crops, directly influencing market prices and orchard revenues. Enhancing has therefore become a critical objective in both production scientific research. External fruits typically include size, coloration, shape, uniformity, consistency. Internal refer to nutritional value fruits, which largely determine their flavor palatability. Over past decade, significant progress been made understanding formation regulatory mechanisms quality, with numerous key functional genes associated being identified. While substantial advancements have achieved studying specific aspects there remains lack comprehensive systematic reviews addressing overall physiology interplay among various traits, diversity mechanisms. Using Chinese pears as an example, this review summarizes research regulation over five years. Key metabolic such sweetness, color, texture, physiological disorders; factors stone cell formation; sugar content regulation; roles plant hormones including ethylene, gibberellins, abscisic acid; translational post-translational modifications ubiquitination, methylation, acetylation; well application genomic sequencing technologies. Furthermore, offers practical suggestions for improving pear provides insights researchers related fields. Finally, future trends are discussed, offering forward-looking perspective advancing field.

Constitutive photomorpogenic dwarf (CPD) is a pivotal enzyme gene for brassinolide (BR) synthesis and plays an important role in plant growth, including increasing biomass height, elongating cells, promoting xylem differentiation. However, little known about the function of CPD sugar beet. In current study, we isolated from Beta vulgaris L. (BvCPD), which encodes protein localized nucleus, cell membrane, wall. BvCPD was strongly expressed parenchyma cells vascular bundles. The transgenic beet overexpressing exhibited larger diameter than that wild type (WT), mainly owing to increased number size enlarged lumen area vessel xylem. Additionally, overexpression endogenous BR, causing changes content auxin (IAA) gibberellin (GA) accumulation cellulose lignin cambium 1-4 rings taproot.
