Different Functions of , a Drought-Responsive AP2/ERF Transcription Factor, in Regulating Root Development Between and Sweetpotato.

Plant root systems are essential for the uptake of water and nutrients from soil and are positively correlated to yield in many crops including the sweetpotato, (L.) Lam. Here, we isolated and functionally characterized , a novel nuclear-localized gene encoding the AP2/ERF transcription factor, from sweetpotato.

Overexpression of 4-hydroxyphenylpyruvate dioxygenase (IbHPPD) increases abiotic stress tolerance in transgenic sweetpotato plants.

Tocopherols are lipid-soluble compounds regarded as vitamin E compounds and they function as antioxidants in scavenging lipid peroxyl radicals and quenching reactive oxygen species (ROS). In our previous studies, we isolated five tocopherol biosynthesis genes from sweetpotato (Ipomoea batatas [L.] Lam) plants including 4-hydroxyphenylpyruvate dioxygenase (IbHPPD).

Effects of exogenous phytohormones on chlorogenic acid accumulation and pathway-associated gene expressions in sweetpotato stem tips.

Sweetpotato (Ipomoea batatas [L.] Lam.) stem tips, which contain high concentrations of chlorogenic acid (CGA), are useful as a physiologically functional food to protect against some serious diseases.

Transgenic sweetpotato plants overexpressing tocopherol cyclase display enhanced α-tocopherol content and abiotic stress tolerance.

Oxidative stress caused by reactive oxygen species (ROS) under various environmental stresses significantly reduces plant productivity. Tocopherols (collectively known as vitamin E) are a group of lipophilic antioxidants that protect cellular components against oxidative stress. Previously, we isolated five tocopherol biosynthesis genes from sweetpotato (Ipomoea batatas [L.

IbMPK3/IbMPK6-mediated IbSPF1 phosphorylation promotes tolerance to bacterial pathogen in sweetpotato.

IbSPF1, a novel target of IbMPK3/IbMPK6, regulates biotic stress response in sweetpotato. Environmental stresses due to biotic and abiotic factors negatively affect crop quality and productivity. To minimize the damage caused by these factors, numerous stress signaling pathways are activated in plants.

De novo transcriptome sequencing and gene expression profiling of sweet potato leaves during low temperature stress and recovery.

Sweetpotato [Ipomoea batatas (L.) Lam] is an important crop used for food, animal feed, and production of industrial materials. Although it is adapted to a wide range of unfavorable conditions, including drought and high salt, sweetpotato is vulnerable to low temperature, making it difficult to cultivate in low temperature regions.

De novo sequencing and comprehensive analysis of the mutant transcriptome from purple sweet potato (Ipomoea batatas L.).

Purple sweet potatoes, rich in anthocyanin, have been widely favored in light of increasing awareness of health and food safety. In this study, a mutant of purple sweet potato (white peel and flesh) was used to study anthocyanin metabolism by high-throughput RNA sequencing and comparative analysis of the mutant and wild type transcriptomes. A total of 88,509 unigenes ranging from 200nt to 14,986nt with an average length of 849nt were obtained.
