Diversity of Culture dependent endophytic bacteria isolated from leguminous agroforestry trees in western Kenya
(Research square, 2022)Plants have diverse and vast niches colonized by endophytic microorganisms that promote the well being of host plant. These microbes inhabit internal plant tissues with no signs of ill health. Bacterial endophytes from ... -
Ecological implications of the ẟ13C values of plant species growing in natural environment, greenhouse and plant respired carbon dioxide (captured as carbonate).
(Research Gate, 2017)ẟ13C values have been used to differentiate the C3 plant species from the C4 species. Light isotope (12C) is favoured against the heavier isotope (13C) during the carbon fractionation in plant species. The ẟ13C valuesof ... -
