Abstract Sirtuins (SRTs) are a group of nicotinamide adenine dinucleotide (NAD + )‐dependent deacetylase that target both histone and nonhistone proteins. The biological function SRT in horticultural plants has been rarely studied. In this study, FaSRT1‐2 was identified as key member the 8 FaSRTs encoded cultivated strawberry genome. Transient overexpression fruit accelerated ripening, increased content anthocyanins sugars, enhanced ripening‐related gene expression. Moreover, stable transformation resulted vegetative growth, sensitivity to heat stress susceptibility Botrytis cinerea infection. Interestingly, knocking out homologous woodland had opposite effects. Additionally, we found stress‐related hormone abscisic acid (ABA) decreased, while growth‐related gibberellin (GA) concentration lines. Gene expression analysis revealed induction shock proteins, transcription factors, antioxidant genes ‐overexpressed knocked‐out impact. conclusion, our findings demonstrated could positively promote plant growth ripening by affecting ABA GA pathways. However, it negatively regulates resistance B. infection influencing related

Citric acid is the primary organic that affects taste of strawberry fruit. Glycolysis supplies key substrates for tricarboxylic cycle (TCA cycle). However, little known about regulatory mechanisms glycolytic genes on citric metabolism in fruits. In this study, content fruit displayed a trend rising and decreasing from initial red stage to full then dark stage. Thus, difference metabolic regulation was suspected during development. addition, overexpression either cytoplasm glyceraldehyde-3-phosphate dehydrogenase (FxaC_14g13400, namely

Hexokinase1 (HXK1) is a bifunctional enzyme that plays indispensable roles in plant growth, nitrogen utilization, and stress resistance. However, information on the HXK family members of strawberries their functions glucose sensing metabolic regulation scarce. In present study, four HXKs were firstly identified genome Fragaria vesca F. pentaphylla. The conserved domains HXK1s confirmed, site-directed mutation (S177A) was introduced into FpHXK1. FpHXK1, which shares highest identity with AtHXK1 able to restore sensitivity developmental defects Arabidopsis gin2-1 mutant, but not its kinase-activity-impaired mutant (FpHXK1S177A ). transcription FpHXK1 dramatically up-regulated under PEG-simulated drought conditions. inhibition kinase activity delayed strawberry plant's responses stress. Transient overexpression kinase-impaired differentially affected level glucose, sucrose, anthocyanins, total phenols fruits. All these results indicated acting as sensor, involved response sugar metabolism depending activity.

Phosphoenolpyruvate (PEP) plays a key role in the development of plants and exists wide variety species. Research on metabolic activities PEP has received increasing attention. regulates multiple processes plant growth development. This article provides comprehensive summary these pathways, including embryo formation, root development, synthesis secondary metabolites, formation lignification. We also summarize new findings, PEP’s nodule energy sensing carbon allocation under influence ozone. review displays complex differential regulatory pathways reference for basic applied research metabolism plants.
