Plastid genome evolution in leafless members of the orchid subfamily Orchidoideae, with a focus on Degranvillea dermaptera
<p><strong>Premise</strong>: Leafless, heterotrophic plants are prime examples of organismal modification, the genomic consequences of which have received considerable interest. In particular, plastid genomes (plastomes) are being sequenced at a high rate, allowing continual refinement of conceptual models of reductive evolution in heterotrophs. Yet, numerous sampling gaps exist, hindering the ability to conduct comprehensive phylogenomic analyses in these plants. </p><p><strong>Methods</strong>: We sequenced and analyzed the plastome of <i>Degranvillea dermaptera</i>, a rarely collected, leafless orchid species from South America about which little is known, including its phylogenetic affinities. </p><p><strong>Key Results</strong>: We revealed the most reduced plastome sequenced to date among the orchid subfamily Orchidoideae. <i>Degranvillea</i> has lost the majority of genes found in leafy autotrophic species, is structurally rearranged, and has similar gene content to the most reduced plastomes among the orchids. We found strong evidence for the placement of <i>Degranvillea</i> within the subtribe Spiranthinae using models that explicitly account for heterotachy, or lineage-specific evolutionary rate variation over time. We further found evidence of relaxed selection on several genes and correlations among substitution rates and several other "traits" of the plastome among leafless members of orchid subfamily Orchidoideae. </p><p><strong>Conclusions</strong>: Our findings advance knowledge on the phylogenetic relationships and paths of plastid genome evolution among the orchids, which have experienced more independent transitions to heterotrophy than any other plant family. This study demonstrates the importance of herbarium collections in comparative genomics of poorly known species of conservation concern. </p>

Extensive pollinator sharing does not promote character displacement in two orchid congeners
<p>Pollinator sharing between close relatives can be costly, which can promote pollination niche partitioning and floral divergence. This should be reflected by a higher species divergence in sympatry than in allopatry.</p> <p>We tested this hypothesis in two orchid congeners with overlapping distributions and flowering times. We characterized floral traits and pollination niches and quantified pollen limitation in 15 pure and mixed populations, and we measured phenotypic selection on floral traits and performed controlled crosses in one mixed site.</p> <p>Most floral traits differed between species, yet pollinator sharing was extensive. Only the timing of scent emission diverged more in mixed than in pure sites, and this was not mirrored by the timing of pollinator visitation. We did not detect divergent selection on floral traits. Seed production was pollen limited in most populations, but not more severely in mixed than in pure sites. Interspecific crosses produced the same or a higher proportion of viable seeds than intraspecific ones.</p> <p>The two orchid species attract the same pollinator species despite showing divergent floral traits. Yet, this does not promote character displacement, implying a low cost of pollinator sharing. Our results highlight the importance of characterizing both traits and ecological niches in character displacement studies.</p>
