Exploring the Microbiota of East African Indigenous Leafy Greens for Plant Growth, Health, and Resilience

Abstract: Indigenous leafy green vegetable crops provide a promising nutritious alternative for East African agriculture under a changing climate; they are better able to cope with biotic and abiotic stresses than cosmopolitan vegetable crops. To verify our hypothesis that the associated microbiome is involved, we studied archaeal and bacterial communities of four locally popular leafy green crops in Uganda (Bidens pilosa, Solanum scabrum, Abelmoschus esculentus, and Gynandropsis gynandra) and of four plant microhabitat… Show more

“…Sphingomonas and Pseudomonas were previously found to be abundant in apple flower [75] and fruit [76] microbiomes. Moreover, phyllosphere-adapted bacterial genera like Methylobacterium and Sphingomonas [2,77] are known to commonly compose the core of phyllosphere microbiomes where they can have implications for plant growth promotion and pathogen suppression [11,[78][79][80], and even for strawberry flavor [12]. Sphingomonas was previously shown to have a high niche versatility in the phyllosphere; it was detected in the core microbiomes of tomato trichomes as well as apple fruits [76,81].…”

“…It is made The copyright holder for this preprint this version posted December 2, 2020. ; https://doi.org/10.1101/2020.12.02.406132 doi: bioRxiv preprint from direct seeding during vaginal birth. It is yet unknown whether methanogens such as Methanobrevibacter* are acquired perinatally and escape detection early in life or if they colonise the GIT via another source such as the BE or dietary products like yoghurt, organic milk and vegetables (Brusa et al, 1998;Taffner, Bergna, et al, 2020;Taffner, Laggner, et al, 2020;van de Pol et al, 2017). The latter scenario is plausible as methanogens coevolved with animals (Borrel et al, 2017;Youngblut et al, 2020) and thus, show strong adaption to the human GIT.…”

“…This introduces a new potential transmission pathway, which is especially interesting with respect to infants, as it presents another way in which they can acquire microbes aside from direct seeding during vaginal birth. It is still not know whether methanogens such as Methanobrevibacter * are acquired perinatal and escape detection early in life or colonise the GIT via another source, such as the BE or dietary products like yoghurt, organic milk and vegetables [96–99]. The latter scenario is plausible, as methanogens co-evolved with animals [56, 100] and, thus, have adapted to the human GIT.…”

“…Blackjack plants can flourish soils with light, moderate and heavy rains and flourish in loose soil containing high organic matter. In addition, blackjack can tolerate saline soil as it can survive in the soil with pH ranging from 4 to 9 [ 39 ]. Generally, blackjack plants grow in rich soil in the wild, planting fields, and home gardens.…”
