Mid rift valley of east Shewa, Ethiopia is among the potential commercial irrigated intensive vegetable production areas [1] supplying a variety of vegetables to every corners of the country. Onion, tomato, maize, kale, hot pepper, watermelon, green bean and head cabbage are among the major vegetable crops widely produced for national and local markets. Okra, cucurbit and sweet melon are also c...

Bacterial genes responsible for poly(3-hydroxybutyrate) (PHB) biosynthesis were targeted to plant peroxisomes by adding a carboxy-terminal targeting sequence. The enzymes evidently were transported into peroxisomes, retained their catalytic activity, and reacted with peroxisomally available precursors because PHB synthesis in transgenic plant cells was localized to peroxisomes. Up to 2 mg/g fre...

There is no direct evidence of the effect of lignin metabolism on early storage root development in sweet potato. In this study, we found that heterologous expression of the maize leaf color (Lc) gene in sweet potato increased anthocyanin pigment accumulation in the whole plant and resulted in reduced size with an increased length/width ratio, low yield and less starch content in the early stor...

Sweet sorghum is tolerant to high temperature and drought and can be considered as an alternative crop to sugar beet and maize in Iran. In this study, the effects of nitrogen and potassium fertilizers on growth parameters including stem height, stem diameter, stem fresh weight, total fresh weight; carbohydrate contents including total sugar, brix value, sucrose content and purify; and juice ext...

In Mexico, about one third of school-age population is overweight or obese and the diet is one of the main determinants. The purpose of this study was to identify the dietary patterns of Mexican school-age children and to determine their association with the risk of overweight/obesity. This study included 8252 school-age children who participated in the 2006 National Health and Nutrition Survey...

The aim of this study was to compare the expression patterns of superoxide dismutase genes (sod2, sod3.4, sod9 and sodB) in seedling leaves of the Zea mays L. Tasty Sweet (susceptible) and Ambrozja (relatively resistant) cultivars infested with one of two hemipteran species, namely monophagous Sitobion avenae F. (grain aphid) or oligophagous Rhopalosiphum padi L. (bird cherry-oat aphid). Second...

Uganda is dominated by agriculture with over 80 percent of the 24.6 million people involved in subsistence farming. The most important cereals are maize, finger millet and sorghum in that order. Finger millet is the second most important cereal in Uganda after maize and exceeding sorghum both in area and production. It is the staple food for over 50% of the country’s 24.6 million people and inc...

This report describes a process for delivering foreign genes into maize cells that does not require the removal of cell walls and is capable of delivering DNA into embryogenic and nonembryogenic tissues. Plasmid harboring a chimeric chloramphenicol acetyltransferase (CAT) gene was adsorbed to the surface of microscopic tungsten particles (microprojectiles). These microprojectiles were then acce...

Abstract Background Fall armyworm (FAW) Spodoptera frugiperda , also called ‘whorlworm’ is a global pest threatening maize production. Larvae stay in the whorl of maize/sweet corn and efficient delivery insecticides or bio-agents major issue for its successful management. Biological control FAW through entomopathogenic nematodes (EPNs) offers promise, as EPNs are soil colonizers commercially av...
