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...
SWEET (Sugars Will Eventually be Exported Transporter) proteins, a novel family of sugar transporters, mediate the diffusion sugars across cell membranes and acts as key players in sucrose phloem loading. Manipulation genes plants leads to various effects on resistance biotic abiotic stresses due disruption efflux changes distribution. In this study, member gene family, IbSWEET10, was cloned from sweet potato line ND98. mRNA expression analysis promoter GUS Arabidopsis showed that IbSWEET10...
WRKYs play important roles in plant growth, defense regulation, and stress response. However, the mechanisms through which are involved drought salt tolerance have been rarely characterized sweetpotato [Ipomoea batatas (L.) Lam.].

The IbWRKY2 localized nucleus. full-length protein exhibited transactivation activity, active domain located N-terminal region....
Soil salinity and drought limit sweet potato yield. Scavenging of reactive oxygen species (ROS) by peroxidases (PRXs) is essential during plant stress responses, but how PRX expression regulated under abiotic not well understood. Here, we report that the B-box (BBX) family transcription factor IbBBX24 activates class III peroxidase gene IbPRX17 binding to its promoter. Overexpression significantly improved tolerance salt stresses, whereas reducing increased their susceptibility. Under...
Summary Drought limits crop development and yields. bHLH (basic helix–loop–helix) transcription factors play critical roles in regulating the drought response many plants, but their this process sweet potato are unknown. Here, we report that two proteins, IbbHLH118 IbbHLH66, opposite ABA‐mediated potato. ABA treatment repressed expression induced IbbHLH66 drought‐tolerant line Xushu55‐2. Overexpressing reduced tolerance, whereas overexpressing enhanced directly binds to E‐boxes promoters of...
ABSTRACT Sweet potato ( Ipomoea batatas [L.] Lam.) is a crucial staple and bioenergy crop. Its abiotic stress tolerance holds significant importance in fully utilizing marginal lands. Transcriptional processes regulate responses, yet the molecular regulatory mechanisms sweet remain unclear. In this study, NAC (NAM, ATAF1/2, CUC2) transcription factor, IbNAC087 , was identified, which commonly upregulated salt‐ drought‐tolerant germplasms. Overexpression of increased salt drought by...
As a major worldwide root crop, the mechanism underlying storage yield formation has always been hot topic in sweet potato [Ipomoea batatas (L.) Lam.]. Previously, we conducted transcriptome database of differentially expressed genes between cultivated cultivar "Xushu18," its diploid wild relative Ipomoea triloba without root, and their interspecific somatic hybrid XT1 with medium-sized root. We selected one these candidate genes, IbNF-YA1, for subsequent analysis. IbNF-YA1 encodes nuclear...
