The average yield of sweet potato (Ipomoea batatas (L.) Lam.) in Brazil is below the crop potential, and appropriate cultural practices more productive cultivars are needed to improve yield. Beauregard cultivar, originally from United States, has shown high potential. This study evaluated performance features agronomic importance cultivar comparison local eight sweet-potato clones Brazilian reg...

Agrobacterium rhizogenes and Agrobacterium tumefaciens are plant pathogenic bacteria capable of transferring DNA fragments [transfer DNA (T-DNA)] bearing functional genes into the host plant genome. This naturally occurring mechanism has been adapted by plant biotechnologists to develop genetically modified crops that today are grown on more than 10% of the world's arable land, although their u...

Refining food recipes with orange-fleshed sweet potato (OFSP) has the potential to improve dietary intake of vitamin A. The objectives of this study were to utilize OFSP in the development of two composite bread types and to assess their contribution to dietary intake of vitamin A using the dietary reference intake of lactating mothers. Two composite OFSP-wheat flour bread recipes-vita butter b...

BACKGROUND Food intake is regulated by the complex interaction of psychological and physiological events associated with ingestion. Food that increases short-term satiety decreases the amount of energy ingested subsequently and thus could potentially help in weight management in the long run. Potato, a common starchy tuber in our environment is believed to contain substances that can help maint...

Cigarette smoke contains around 4000 chemical substances including free radicals and carcinogens, which are xenobiotic agents in the body, affecting the reproductive system. Purple sweet potatoes contain the color pigment anthocyanin. The purple color pigment (anthocyanin) in purple sweet potatoes is a beneficial antioxidant because it can react with free radicals that can cause damage in the b...

Sweet potato [Ipomoea batatas (L) Lam] yields currently stand at 4.5 t ha-1 on smallholder farms in Uganda, despite the attainable yield (45-48 t ha-1) of NASPOT 11 cultivar comparable to the potential yield (45 t ha-1) in sub-Saharan Africa (SSA). On-farm field experiments were conducted for two seasons in the Mt Elgon High Farmlands and Lake Victoria Crescent agro-ecological zones in Uganda t...

BACKGROUND Sweet potato (Ipomoea batatas L. [Lam.]) ranks among the top six most important food crops in the world. It is widely grown throughout the world with high and stable yield, strong adaptability, rich nutrient content, and multiple uses. However, little is known about the molecular biology of this important non-model organism due to lack of genomic resources. Hence, studies based on hi...
