G-protein coupled receptors (GPCRs) are the largest family of membrane proteins, as key components of signal transduction pathways. Despite the current knowledge, GPCRs in plants are not well characterized if compared with animals and are still a matter of controversy. The availability of plant genomes allows the prediction and characterization of diverse GPCRs, as for several species the repertoire of GPCRs remains unclear. As a contribution to this problem, we present the in silico analyses of putative GPCRs candidates from Arabidopsis thaliana, Capsicum annuum, Glycine max, Manihot esculenta, Medicago truncatula, Oryza sativa, Phaseolus vulgaris, Populus trichocarpa, Ricinus communis, Solanum lycopersicum, Solanum tuberosum, Sorghum bicolor, Theobroma cacao, Triticum aestivum, Vitis vinifera and Zea mays proteomes. From a total of 997,435 proteins collected, the sequences were selected by length, reducing the initial collection to 487,012. GPCRpipe program predicted 60 GPCRs candidates, ranging from none (Capsicum annuum) to 12 candidates (Populus trichocarpa) (median = 3 ± 2.90).The Neighbor joining dendrogram of the 60 predicted GPCR candidates grouped the proteins in three clades. These findings may indicate that GPCR in plants are involved in drought stress responses.
