A Metagenomic Study of DNA Viruses from Samples of Local Varieties of Common Bean in Kenya
A metagenomic study of DNA viruses from samples of local varieties of common bean in Kenya James M. Wainaina1, Elijah Ateka2, Timothy Makori2, Monica A. Kehoe3 and Laura M. Boykin1 1 School of Molecular Sciences and Australian Research Council Centre of Excellence in Plant Energy Biology, The University of Western Australia, Crawley, WA, Australia 2 Department of Horticulture, Jomo Kenyatta University of Agriculture and Technology, Nairobi, Kenya 3 Diagnostic Laboratory Service, Plant Pathology, Department of Primary Industries and Regional Development, South Perth, WA, Australia ABSTRACT Common bean (Phaseolus vulgaris L.) is the primary source of protein and nutrients in the majority of households in sub-Saharan Africa. However, pests and viral diseases are key drivers in the reduction of bean production. To date, the majority of viruses reported in beans have been RNA viruses. In this study, we carried out a viral metagenomic analysis on virus symptomatic bean plants. Our virus detection pipeline identified three viral fragments of the double-stranded DNA virus Pelargonium vein banding virus (PVBV) (family, Caulimoviridae, genus Badnavirus). This is the first report of the dsDNA virus and specifically PVBV in legumes to our knowledge. In addition two previously reported +ssRNA viruses the bean common mosaic necrosis virus (BCMNVA) (Potyviridae) and aphid lethal paralysis virus (ALPV) (Dicistroviridae) were identified. Bayesian phylogenetic analysis of the Badnavirus (PVBV) using amino acid sequences of the RT/RNA-dependent DNA polymerase region showed the Kenyan sequence (SRF019_MK014483) was closely matched with two Badnavirus viruses: Dracaena mottle virus (DrMV) (YP_610965) and Lucky bamboo bacilliform virus (ABR01170). Phylogenetic analysis Submitted 17 July 2018 Accepted 16 January 2019 of BCMNVA was based on amino acid sequences of the Nib region. -

A Passion to Defeat the Whitefly 6 November 2015, by Mara Kerkez
A passion to defeat the whitefly 6 November 2015, by Mara Kerkez unacceptable, and my skills could be applied to the problem. I hadn't considered before that I could pass them on to the next generation of scientists. I decided the best use of my time on Earth was to make a difference here." A computational biologist, Boykin uses genomics, supercomputing and phylogenetics to identify whitefly species, gathering information necessary for researchers to modify cassava to resist both insect and virus. To accelerate progress, she launched WhiteFlyBase — the world's first database of whitefly genetic information — with the hope of eradicating whitefly and bringing food security to The whitefly is destroying half of East Africa's main food source, and yet it is no bigger than the head of a pin. East Africa. Credit: Laura Boykin Tackling the cassava whitefly University of New Mexico alumna Laura Boykin (Ph.D. 2003) was recently featured in the article, "12 Badass Scientists...Who Also Happen to be Women" released by Ted Fellows, a program that falls under the purview of TED (Technology, Entertainment, Design) the organization whose motto is to make great ideas accessible and spark conversation. TED Fellows are individuals lauded for their innovative solutions to the world's most complex challenges today. For Boykin, the challenge came in the form of the whitefly, an insect that transmits Laura Boykin (r); fellow researcher Donald Kachigamba a virus to cassava, a root vegetable that nearly 800 (l); and scientist and cassava diseases expert known only million people worldwide rely on for sustenance, as John (c), inspect African whiteflies feeding on cassava some for income. -

The International Institute of Tropical Agriculture led five national cassava breeding programs (Malawi, Mozambique, Kenya, Tanzania and Uganda) in virus-cleaning and exchanging elite cassava germplasm resistant to both diseases. This paper documents the experiences and lessons learned from the process. Thirty-one clones (25 elite, two standard and four national) were submitted by the five breeding programs to the Natural Resources Institute and Kenya Plant Health Inspectorate Services for virus cleaning and indexing. Subsequently, ca 75 in- vitro virus-indexed plantlets per clone were sent to Genetic Technologies International Limited (GTIL), a private tissue culture (TC) lab in Kenya, and micro-propagated to produce ≥1500 plantlets. After fulfilling all the formal procedures of germplasm exchange between countries ≥300 plantlets per clone were sent to each partner country. -

One of the major limitations of sweet potato production are viral infections. In this study, we used a combination of whole genome sequences from a field isolate from Kenya and those available in GenBank. Sequences of four sweet potato viruses: sweet potato feathery mottle virus (SPFMV), sweet potato virus C (SPVC), sweet potato chlorotic stunt virus (SPCSV), sweet potato chlorotic fleck virus(SPCFV) were obtained from the Kenyan sample. SPFMV sequences both from this study and from GenBank were found to be recombinant.
