The role of Kenya in the trans-african spread of maize streak virus strain a
(Elsevier, 2017-03-15)Maize streak virus (MSV), the causal agent of maize streak disease (MSD), is the most important viral pathogen of Africa’s staple food crop, maize. Previous phylogeographic analyses have revealed that the most widely-distributed ... -
UGbS-Flex, a novel bioinformatics pipeline for imputation-free SNP discovery in polyploids without a reference genome: finger millet as a case study
(BioMed Central, 2018-12-01)Research on orphan crops is often hindered by a lack of genomic resources. With the advent of affordable sequencing technologies, genotyping an entire genome or, for large-genome species, a representative fraction of the ... -
Mechanistic understanding of iron toxicity tolerance in contrasting rice varieties from Africa: 1. Morpho-physiological and biochemical responses
(CSIRO PUBLISHING, 2019-01-21)Iron (Fe) is a fundamental element involved in various plant metabolic processes. However, when Fe uptake is excessive, it becomes toxic to the plant and disrupts cellular homeostasis. The aim of this study was to determine ... -
Mechanistic understanding of iron toxicity tolerance in contrasting rice varieties from Africa: 2. Root oxidation ability and oxidative stress control
