Characterization of Genes and Promoters, Transformation and Transgenic Development in Sweet Potato

Sweet potato belongs to Ipomoea series batatas and is thought to have originated in Central America and Northern South America. World sweet potato production is around 106 million tons in an area of about 8.1 million ha. Asia is the world’s largest sweet potato-producing region and China is the world’s leading sweet potato-producing country accounting for about 76% of production. Sweet potato h...

Enhanced salt stress tolerance in transgenic potato plants expressing IbMYB1, a sweet potato transcription factor.

IbMYB1, a transcription factor (TF) for R2R3-type MYB TFs, is a key regulator of anthocyanin biosynthesis during storage of sweet potatoes. Anthocyanins provide important antioxidants of nutritional value to humans, and also protect plants from oxidative stress. This study aimed to increase transgenic potatoes' (Solanum tuberosum cv. LongShu No.3) tolerance to environmental stress and enhance t...

Detection of sweet potato virus C, sweet potato virus 2 and sweet potato feathery mottle virus in Portugal.

Field sweet potato plants showing virus-like symptoms, as stunting, leaf distortion, mosaic and chlorosis, were collected in southwest Portugal and tested for the presence of four potyviruses, sweet potato virus C (SPVC), sweet potato virus 2 (SPV2), sweet potato feathery mottle virus (SPFMV), sweet potato virus G (SPVG), and the crinivirus sweet potato chlorotic stunt virus (SPCSV). DsRNA frac...

Sweet-potato Scurf

The scurf disease of the sweet potato (Ipomoea batatas) was first described by Halsted, who published a brief account of it in 1890. To the fungus he gave the name Monilochaetes infuscans, a new genus and species, of which, unfortunately, he gave no technical description. For many years following his pioneer work little or no attention was given to sweet-potato diseases. This very common and in...
