Comparative microbiome diversity in root-nodules of three species used in push-pull cropping system.

Background: species used as intercrops in push-pull cropping systems are known to repel insect-pests, suppress species weeds, and shift soil microbiome. However, the mechanisms through which species impact the soil microbiome, either through its root exudates, changes in soil nutrition, or shading microbes from its nodules into the rhizosphere, are less understood. Here, we investigated the diversity of root-nodule microbial communities of three species- (SLD), (GLD), and (AID) which are currently used in smallholder maize push-pull technology (PPT).

Competitive Plant-Mediated and Intraguild Predation Interactions of the Invasive and Resident Stemborers and in Maize Cropping Systems in Kenya.

Following its recent invasion of African countries, fall armyworm (FAW), Spodoptera frugiperda (Lepidoptera: Noctuidae), now co-exists with resident stemborers such as Busseola fusca (Lepidoptera: Noctuidae) and Chilo partellus (Lepidoptera: Crambidae) causing severe damage to maize crops. Due to niche overlap, interspecific interactions occur among the three species, but the mechanisms and degree remain unclear. In this study, we assessed plant-mediated intraspecific and interspecific interactions, predation in laboratory and semi-field settings, and larval field occurrence of S.

Occurrence of a Novel Strain of Moroccan Watermelon Mosaic Virus Infecting Pumpkins in Kenya.

The Moroccan watermelon mosaic virus (MWMV) naturally infects and severely threatens production of cucurbits and papaya. In this study, we identified and characterized MWMV isolated from pumpkin () intercropped with MWMV-infected papaya plants through next-generation sequencing (NGS) and Sanger sequencing approaches. Complete MWMV genome sequences were obtained from two pumpkin samples through NGS and validated using Sanger sequencing.

Metagenomic Analysis of Plant Viruses Associated With Papaya Ringspot Disease in L. in Kenya.

L. is an important fruit crop grown by small- and large-scale farmers in Kenya for local and export markets. However, its production is constrained by papaya ringspot disease (PRSD).
