AbstractBegonia is an important horticultural plant group, as well as one of the most speciose Angiosperm genera, with over 2000 described species. Genus wide studies of genome size have shown that Begonia has a highly variable genome size, and analysis of paralog pairs has previously suggested that Begonia underwent a whole genome duplication. We address the contribution of gene duplication to the generation of diversity in Begonia using a multi-tissue RNA-seq approach. We chose to focus on chalcone synthase (CHS), a gene family having been shown to be involved in biotic and abiotic stress responses in other plant species, in particular its importance in maximising the use of variable light levels in tropical plants. We used RNA-seq to sample six tissues across two closely related but ecologically and morphologically divergent species, Begonia conchifolia and B. plebeja, yielding 17,012 and 19,969 annotated unigenes respectively. We identified the chalcone synthase gene family members in our Begonia study species, as well as in Hillebrandia sandwicensis, the monotypic sister genus to Begonia, Cucumis sativus, Arabidopsis thaliana, and Zea mays. Phylogenetic analysis suggested the CHS gene family has high duplicate turnover, all members of CHS identified in Begonia arising recently, after the divergence of Begonia and Cucumis. Expression profiles were similar within orthologous pairs, but we saw high inter-ortholog expression variation. Sequence analysis showed relaxed selective constraints on some ortholog pairs, with substitutions at conserved sites. Evidence of pseudogenisation and species specific duplication indicate that lineage specific differences are already beginning to accumulate since the divergence of our study species. We conclude that there is evidence for a role of gene duplication in generating diversity through sequence and expression divergence in Begonia.

The mammalian mdr gene family comprises a small number of closely related genes. Previously, we have shown that one member, mdr1, has the capacity to convey multidrug resistance to drug-sensitive recipient cells in a gene transfer protocol. However, the functional characteristics of other members of this gene family have not been examined. In this report, we characterize a second member of the mdr gene family which we designated mdr2. We determined the nucleotide sequence corresponding to the complete coding region of this mdr2 transcript. The predicted amino acid sequence of this protein (1,276 amino acids) showed that it is a membrane glycoprotein highly homologous to mdr1 (85%), strongly suggesting that both genes originate from a common ancestor. Regions of divergence between mdr1 and mdr2 proteins are concentrated in two discrete segments of the predicted polypeptides, each approximately 100 residues in length. The mdr2 protein appears to be formed by the duplication of a structural unit which encodes three putative transmembrane loops and a predicted nucleotide-binding fold and is highly homologous to bacterial transport proteins such as hlyB. This strong homology suggests that mdr2 also participates in an energy-dependent membrane transport process. However, the direct relationship, if any, of this new member of the mdr family to multidrug resistance remains to be established. Knowledge of the complete nucleotide sequence and predicted amino acid sequence of the mdr2 gene product will enable the preparation of gene-specific probes and antibodies necessary to study the functional role of this gene in multidrug resistance and normal physiological processes.

ABSTRACT Several genes in the trichothecene biosynthetic pathway ofFusarium sporotrichioides have been shown to reside in a gene cluster. Sequence analysis of a cloned DNA fragment located 3.8 kb downstream from TRI5 has led to the identification of the TRI11 gene. The nucleotide sequence ofTRI11 predicts a polypeptide of 492 residues (M r = 55,579) with significant similarity to members of the cytochrome P-450 superfamily. TRI11 is most similar to several fungal cytochromes P-450 (23 to 27% identity) but is sufficiently distinct to define a new cytochrome P-450 gene family, designated CYP65A1. Disruption of TRI11 results in an altered trichothecene production phenotype characterized by the accumulation of isotrichodermin, a trichothecene pathway intermediate. The evidence suggests that TRI11 encodes a C-15 hydroxylase involved in trichothecene biosynthesis.
