“…For comparison, the sugar concentration on tomato leaves was determined at 1.55 g/g (26). Organic carbon concentrations reported in this study, as well as those previously published for T. aphylla (4,30), are thus approximately 3 orders of magnitude higher. In addition to providing rich carbon and energy sources for the phyllosphere bacteria, it is likely that these compounds also aid in desiccation and osmotic stress responses.…”

The leaf surfaces of Tamarix, a salt-secreting desert tree, harbor a diverse community of microbial epiphytes. This ecosystem presents a unique combination of ecological characteristics and imposes a set of extreme stress conditions. The composition of the microbial community along ecological gradients was studied from analyses of microbial richness and diversity in the phyllosphere of three Tamarix species in the Mediterranean and Dead Sea regions in Israel and in two locations in the United States. Over 200,000 sequences of the 16S V6 and 18S V9 hypervariable regions revealed a diverse community, with 788 bacterial and 64 eukaryotic genera but only one archaeal genus. Both geographic location and tree species were determinants of microbial community structures, with the former being more dominant. Tree leaves of all three species in the Mediterranean region were dominated by Halomonas and Halobacteria, whereas trees from the Dead Sea area were dominated by Actinomycetales and Bacillales. Our findings demonstrate that microbial phyllosphere communities on different Tamarix species are highly similar in the same locale, whereas trees of the same species that grow in different climatic regions host distinct microbial communities.

“…Phyllosphere, the external surface of plant leaves, is a habitat that has traditionally received low attention in microbial ecology, with most of the initial research being primarily focused on the study of plant-pathogen interactions in cultures of economic interest (Lindow & Brandl, 2003;Belkin et al, 2010). Though still lagging behind rhizosphere studies, phyllosphere research has been a subject of increased interest in recent years (Vorholt, 2012;Rastogi et al, 2013).…”
