Description:
The above-ground surfaces of terrestrial plants, the phyllosphere,
comprise the main interface between the terrestrial biosphere and solar
radiation. It is estimated to host up to 1026 microbial cells that may
intercept part of the photon flux impinging on the leaves. Based on 454-
pyrosequencing generated metagenome data, we report on the existence
of diverse microbial rhodopsins in five distinct phyllospheres from
tamarisk (Tamarix nilotica), soybean (Glycine max), Arabidopsis
(Arabidopsis thaliana), clover (Trifolium repens) and rice (Oryza sativa).
Our findings, for the first time describing microbial rhodopsins from non-aquatic habitats, point toward the potential coexistence of microbial
rhodopsin-based phototrophy and plant chlorophyll-based
photosynthesis, with the different pigments absorbing non-overlapping
fractions of the light spectrum.
