Genome wide identification and expression analysis of gibberellin oxidase family genes in sweet potato and its two diploid relatives [PDF]

Scientific Reports
As essential plant hormones, gibberellins (GAs) regulate various growth and development processes. GA oxidases (GAoxs), including the GA2ox, GA3ox, and GA20ox subgroups, play prominent roles in the synthesis and degradation of GA; however, a systematic ...

Identification and functional characterization of a flavonol synthase gene from sweet potato [Ipomoea batatas (L.) Lam.]

Frontiers in Plant Science, 2023
Flavonol synthase (FLS) is a key enzyme of the flavonoid biosynthetic pathway, which catalyzes the conversion of dihydroflavonols into flavonols. In this study, the FLS gene IbFLS1 was cloned and characterized from sweet potato.

The Role of IAA in Regulating Root Architecture of Sweetpotato (Ipomoea batatas [L.] Lam) in Response to Potassium Deficiency Stress

Plants, 2023
Plants can adapt to the spatial heterogeneity of soil nutrients by changing the morphology and architecture of the root system. Here, we explored the role of auxin in the response of sweetpotato roots to potassium (K+) deficiency stress.

Molecular insights into AabZIP1-mediated regulation on artemisinin biosynthesis and drought tolerance in Artemisia annua

Acta Pharmaceutica Sinica B, 2022
Artemisia annua is the main natural source of artemisinin production. In A. annua, extended drought stress severely reduces its biomass and artemisinin production while short-term water-withholding or abscisic acid (ABA) treatment can increase ...

Evaluation of fumigant and non-fumigant nematicides for management of Rotylenchulus reniformis on sweetpotato

Journal of Nematology, 2023
Reniform nematode (Rotylenchulus reniformis) is a major pest of sweetpotato in many production regions in Southern United States. Applying soil fumigants and non-fumigant nematicides are the primary management strategies available to growers.

Ipomoea batatas HKT1 transporter homolog mediates K+ and Na+ uptake in Saccharomyces cerevisiae

Journal of Integrative Agriculture, 2017
: Soil salinity causes the negative effects on the growth and yield of crops. In this study, two sweet potato (Ipomoea batatas L.) cultivars, Xushu 28 (X-28) and Okinawa 100 (O-100), were examined under 50 and 100 mmol L−1 NaCI stress.
