Menkir, A.Palacios-Rojas, N.Alamu, O.Dias Paes, M.C.Dhliwayo, T.Maziya-Dixon, B.B.Mengesha, W.Ndhlela, T.Oliveira Guimarães, P.E.Pixley, K.Rocheford, T.[Vitamin A-biofortified maize: exploiting native genetic variation for nutrient enrichment]Vitamin A-biofortified maize: exploiting native genetic variation for nutrient enrichment

Maize is a staple food for millions of people in sub-Saharan Africa where a significant number of people suffer from vitamin A deficiency. Yellow maize contains both pro-vitamin A and nonprovitamin A carotenoids with potential health benefits to humans. An improvement in the concentration of thes...


Menkir, A.Liu, W.White, W.S.Maziya-Dixon, B.B.Rocheford, T.[Carotenoid diversity in tropicaladapted yellow maize inbred lines]Carotenoid diversity in tropicaladapted yellow maize inbred lines

Vitamin A Deficiency (VAD) is a major public health problem in Sub-Saharan Africa affecting 33 million preschool-age children. Enrichment of maize varieties with provitamin A could provide sustainable and affordable solution to VAD. This study was conducted to understand the extent of GEI effects...

Menkir, A.Rocheford, T.Maziya-Dixon, B.B.Tanumihardjo, S.[Exploiting natural variation in exotic germplasm for increasing provitaminA carotenoids in tropical maize]Exploiting natural variation in exotic germplasm for increasing provitaminA carotenoids in tropical maize

Background: Biofortification of staple crops is a cost effective and sustainable approach that can help combatvitamin A and other micronutrient deficiencies in developing countries. PCR -based DNA markers distinguishingalleles of three key genes of maize endosperm carotenoid biosynthesis (PSY1, l...


Azmach, G.Gedil, M.Menkir, A.Spillane, Charles[Markertrait association analysis of functional gene markers for provitamin A levels across diverse tropical yellow maize inbred lines]Markertrait association analysis of functional gene markers for provitamin A levels across diverse tropical yellow maize inbred lines

Development of pro-vitamin A (PVA) biofortified staple crops has been promoted as an option for addressing vitamin A deficiency in humans. Recently, crtRBI, lcyE and zep1 genes of carotenoid biosynthesis pathway have been identified as contributors to PVA accumulation in maize endosperm. High phe...
