摘要： Respiratory burst oxidase homologs (RBOHs), which catalyze the production of superoxide from oxygen and NADPH, play key roles in plant growth and development, hormone signaling, and stress responses. Compared with extensive studies in model plants arabidopsis and rice, little is known about RBOHs in other species. This study presents a genome-wide analysis of Rboh family genes in jatropha (Jatropha curcas) as well as the comparison with castor bean (Ricinus communis), another economically important non-food oilseed crop of the Euphorbiaceae family. The family number of seven members identified from the jatropha genome is equal to that present in castor bean, and further phylogenetic analysis assigned these genes into seven groups named RBOHD, -C, -B, -E, -F, -N, and -H. In contrast to a high number of paralogs present in arabidopsis and rice that experienced several rounds of recent wholegenome duplications, no duplicate was identified in both jatropha and castor bean. Conserved synteny and one-to-one orthologous relationship were observed between jatropha and castor bean Rboh genes. Although exon-intron structures are usually highly conserved between orthologs, loss of certain introns was observed for JcRbohB, JcRbohD, and RcRbohN, supporting their divergence. Global gene expression profiling revealed diverse patterns of JcRbohs over various tissues. Moreover, expression patterns of JcRbohs during flower development as well as various stresses were also investigated. These findings will not only improve our knowledge on species-specific evolution of the Rboh gene family, but also provide valuable information for further functional analysis of Rboh genes in jatropha.
