Cultivated sweet potato (Ipomoea batatas) is an important source of food for both humans and domesticated animals. Here, we show that the B-box (BBX) family transcription factor IbBBX24 regulates jasmonic acid (JA) pathway in potato. When was overexpressed potato, JA accumulation increased, whereas silencing this gene decreased levels. RNA sequencing analysis revealed modulates expression genes involved pathway. responses by antagonizing signaling repressor IbJAZ10, which relieves IbJAZ10's...
Sucrose non-fermenting-1-related protein kinase-1 (SnRK1) is an essential energy-sensing regulator and plays a key role in the global control of carbohydrate metabolism. The SnRK1 gene has been found to increase starch accumulation several plant species. However, its roles improving quality have not reported date. In this study, we that IbSnRK1 was highly expressed storage roots sweet potato strongly induced by exogenous sucrose. Its expression followed circandian rhythm. overexpression only...
Abstract Apurinic/apyrimidinic (AP) sites are one of the most abundant DNA lesions and mainly repaired by AP endonucleases (APEs). While eukaryotic genomes encode two APEs, plants usually possess three namely APE1L, APE2, ARP. To date, biological relevance functional divergence plant APEs unclear. Here, we show that have ancient origins, with APE1L clade being plant-specific. In Arabidopsis thaliana, simultaneously mutating but not ARP alone or in combination either results clear...
Abstract Base excision repair and active DNA demethylation produce intermediates with molecules blocked at the 3′-OH end by an aldehyde or phosphate group. However, both physiological consequences of these accumulated single-strand DNAs break 3′-blocked ends (DNA 3′-blocks) signaling pathways responding to unrepaired 3′-blocks remain unclear in plants. Here, we investigated effects on plant development using zinc finger 3'-phosphoesterase (zdp) AP endonuclease2 (ape2) double mutant, which...
Abstract DNA methylation is an important epigenetic mark implicated in selective rRNA gene expression, but the readers and effectors remain largely unknown. Here, we report a protein complex that reads to regulate variant-specific 45S ribosomal RNA (rRNA) expression Arabidopsis (Arabidopsis thaliana). The complex, consisting of METHYL-CpG-BINDING DOMAIN PROTEIN5 (MBD5), MBD6, ALPHA-CRYSTALLIN PROTEIN15.5 (ACD15.5), ACD21.4, directly binds rDNA. While MBD5 MBD6 function redundantly, ACD15.5...
Nitrogen (N) availability is a major limiting factor for plant growth and agricultural productivity. Although the gene regulation network in response to N starvation has been extensively studied, it remains unknown whether an impact on activity of transposable elements (TEs). Here, we report that TEs can be transcriptionally activated Arabidopsis under conditions. Through genetic screening idm1-14 suppressors, cloned GLU1, which encodes glutamate synthase catalyzes synthesis primary...
Nitrogen is an important nutrient for plant development. and carbon metabolisms are tightly linked to physiological functions in plants. In this study, we found that the IbSnRK1 gene was induced by Ca(NO3)2. Its overexpression enhanced nitrogen uptake assimilation transgenic sweetpotato. After Ca(15NO3)2 treatment, 15N atom excess, total N content efficiency (NUE) were significantly increased roots, stems, leaves of plants compared with wild type (WT) empty vector control (VC). Ca(NO3)2...
Phenolic acids are known to reduce root biomass and hinder plant development, but it is unclear how they affect potato traits. Over a 10 year field experiment, we found negative correlation between the yield continuous cropping years. The substantial reduction in adventitious (AR) numbers was be primarily inhibited by soil vanillin accumulation. study also that had more pronounced inhibitory effect on than commonly reported ferulic acid p-hydroxybenzoic acid. decrease attributed of...
Sucrose non-fermenting-1-related protein kinase-1 (SnRK1) regulates carbon and nitrogen metabolism in plants. However, its roles their underlying mechanisms tolerance to abiotic stresses are little known. The present study indicated that the IbSnRK1 gene was strongly induced by NaCl, polyethylene glycol (PEG) 6000, hydrogen peroxide (H2O2), cold (4 °C), abscisic acid (ABA). Its overexpression significantly increased salt, drought, transgenic sweet potato ABA, proline, K+ contents were...
Abstract In practice, late sowing of spring potatoes is commonly adopted to bridge crop rotation and mitigate natural disasters, inadvertently facilitating high-temperature conditions during the latter growth phase, leading diminished tuber yield quality. To avert these setbacks, this experiment explored influence foliar applications plant regulators like Diethyl aminoethyl hexanoate (DTA-6), Uniconazole (S3307), Abscisic acid (S-ABA), Salicylic (SA) on Zhongshu Zao 45 (ZZ45), a late-sowing...
