Transcriptomic Analysis of a Susceptible African Maize Line to Infection.

Maize ( L.) is a staple crop providing food security to millions of people in sub Saharan Africa. , an important fungal pathogen, infects maize causing ' Ear Rot' disease, which decreases maize kernel yield and the quality of the crop harvested.

The Development of a qPCR Assay to Measure Biomass in Maize and the Use of a Biocontrol Strategy to Limit Aflatoxin Production.

colonisation of maize can produce mycotoxins that are detrimental to both human and animal health. Screening of maize lines, resistant to infection, together with a biocontrol strategy, could help minimize subsequent aflatoxin contamination. We developed a qPCR assay to measure biomass and showed that two African maize lines, GAF4 and KDV1, had different fungal loads for the aflatoxigenic isolate (KSM014), fourteen days after infection.

Biogeographical Patterns of Legume-Nodulating Burkholderia spp.: from African Fynbos to Continental Scales.

Unlabelled: Rhizobia of the genus Burkholderia have large-scale distribution ranges and are usually associated with South African papilionoid and South American mimosoid legumes, yet little is known about their genetic structuring at either local or global geographic scales. To understand variation at different spatial scales, from individual legumes in the fynbos (South Africa) to a global context, we analyzed chromosomal (16S rRNA, recA) and symbiosis (nifH, nodA, nodC) gene sequences. We showed that the global diversity of nodulation genes is generally grouped according to the South African papilionoid or South American mimosoid subfamilies, whereas chromosomal sequence data were unrelated to biogeography.

Genetic diversity in tef [Eragrostis tef (Zucc.) Trotter].

Tef [Eragrostis tef (Zucc.) Trotter] is a cereal crop resilient to adverse climatic and soil conditions, and possessing desirable storage properties. Although tef provides high quality food and grows under marginal conditions unsuitable for other cereals, it is considered to be an orphan crop because it has benefited little from genetic improvement.

The genes controlling sucrose utilization in Clostridium beijerinckii NCIMB 8052 constitute an operon.

The sucrose operon of Clostridium beijerinckii NCIMB 8052 comprises four genes, which encode a sucrose-specific enzyme IIBC(Scr) protein of the phosphotransferase system (ScrA), a transcriptional repressor (ScrR), a sucrose hydrolase (ScrB) and an ATP-dependent fructokinase (ScrK). The scrARBK operon was cloned in Escherichia coli in three stages. Initial isolation was achieved by screening a C.
