Abstract Premise Distyly is a condition in which individual plants population express two floral morphs, L‐ and S‐morph, characterized by reciprocal placements of anthers stigmas between morphs. The function distyly requires that pollinators collect pollen from S‐morphs on different parts along their bodies to then deposit it the opposite morph, known as legitimate pollination. However, pollinator groups might differ ability transfer legitimately. Methods We investigated patterns pickup body functional (hummingbirds bees) using preserved specimens analyze role reproductive success Palicourea rigida . measured deposition pollinators, stigmas, fruit production after single visit. Results Pollen S‐flowers appeared segregated hummingbird bee used study. S‐pollen was deposited primarily proximal regions (near head), L‐pollen placed distal (tip proboscis bill). Hummingbirds were more efficient at pollination than bees, particularly S‐stigmas. formation visits both similar. Conclusions morphology distylous flowers allows placement L‐and animal used, facilitating promotion transfer, an observation consistent groups. Also, results show full set one

Common buckwheat (Fagopyrum esculentum) and Tartary tataricum), the two most widely cultivated species, differ greatly in flavonoid content reproductive mode. Here, we report first high-quality chromosome-level genome assembly of common with 1.2 Gb. Comparative genomic analysis revealed that underwent a burst long terminal repeat retrotransposons insertion accompanied by numerous large chromosome rearrangements after divergence from buckwheat. Moreover, multiple gene families involved stress tolerance biosynthesis such as multidrug toxic compound extrusion (MATE) chalcone synthase (CHS) significant expansion buckwheat, especially Integrated multi-omics identified high expression catechin biosynthesis-related genes flower seed rutin being important for differences type between these species. We also candidate key rutin-degrading enzyme (Ft8.2377) was highly expressed seed. In addition, haplotype-resolved locus containing many reportedly associated development pollen, which potentially related to self-incompatibility Our study provides resources facilitating future functional genomics-related research

Since the insights by Charles Darwin, heterostyly, a floral polymorphism with morphs bearing stigmas and anthers at reciprocal heights, has become model system for study of natural selection. Based on his archetypal heterostylous flower, including regular symmetry, few stamens tube, Darwin hypothesised that heterostyly evolved to promote outcrossing through efficient pollen transfer between involving different areas pollinator's body, thus proposing seminal pollination-precision hypothesis. Here we update number other style-length polymorphic taxa 247 genera belonging 34 families, notably expanding known cases 20%. Using phylogenetic comparative analyses across angiosperms, show numerous independent origins associated actinomorphic, tubular flowers low sex organs, fused corolla, pollination long-tongued insects. These associations provide support Darwinian hypothesis as basis convergent evolution angiosperms.

Heterostyly, a plant sexual polymorphism controlled by the S-locus supergene, has evolved numerous times among angiosperm lineages and represents classic example of convergent evolution in form function. Determining whether underlying molecular convergence occurs could provide insights on constraints to floral evolution. Here, we investigated genes distylous Gelsemium (Gelsemiaceae) determine there is evidence with unrelated species. We used several approaches, including anatomical measurements sex-organ development transcriptome whole-genome sequencing, identify components supergene. also performed evolutionary analysis candidate compared them those reported Primula Turnera. The supergene contained four genes, which three appear have originated from gene duplication events within Gelsemiaceae. style-length GeCYP CYP734A50 likely arose same gene, CYP734A1. Three out elegans were hemizygous, as previously genomic genetic distyly distantly related help illuminate architecture involved heterostyly.

Distyly has evolved independently in numerous animal-pollinated angiosperm lineages. Understanding of its molecular basis been restricted to a few species, primarily Primula. Here, we investigate the genetic architecture single diallelic locus (S-locus) supergene, linkage group functionally associated genes, and explore how it may have distylous Nymphoides indica, lineage flowering plants not previously investigated. We assembled haplotype-resolved genomes, used read-coverage-based genome-wide association study (rb-GWAS) locate S-locus co-expression network analysis gene networks underpinning development distyly, comparative genomic analyses origins supergene. identified three linked candidate genes - NinBAS1, NinKHZ2, NinS1 that were only evident short-styled morph hemizygous. Co-expression suggested brassinosteroids contribute dimorphic sex organs morph. Comparative indicated supergene likely via stepwise duplications affected by transposable element activities. Our provides novel insight into structure, regulation, evolution governing distyly N. indica. It also high-quality resources for future research on mechanisms underlying striking evolutionary convergence form function across heterostylous taxa.

Abstract Background and Aims Style dimorphism is one of the polymorphic characteristics flowers in heterostylous plants, which have two types flowers: pin morph, with long styles shorter anthers, thrum short longer anthers. The formation dimorphic has received attention plant world. Previous studies showed that CYP734A50 Primula determined style length limited elongation brassinosteroid metabolic pathway was involved regulation length. However, it unknown whether there are other factors affecting Primula. Methods Differentially expressed genes highly morph were screened based on forbesii transcriptome data. Virus-induced gene silencing used to silence these genes, anatomical changes observed 20 days after injection. Key Results PfPIN5 styles. When silenced, shortened long-homostyle plants by shortening cells. Moreover, increased expression level significantly, increased. results indicated PfPIN5, an auxin efflux transporter gene, contributed P. forbesii. Conclusions implied might also be forbesii, providing a new for elucidating molecular mechanism

Abstract Distyly is an iconic floral polymorphism governed by a supergene, which promotes efficient pollen transfer and outcrossing through reciprocal differences in the position of sexual organs flowers, often coupled with heteromorphic self-incompatibility. has evolved convergently multiple flowering plant lineages, but also broken down repeatedly, resulting homostylous, self-compatible populations elevated rates self-fertilization. Here, we aimed to study genetic causes genomic consequences shift homostyly Linum trigynum, closely related distylous tenue. Building on high-quality genome assembly, show that L. trigynum harbors region homologous dominant haplotype distyly supergene conferring long stamens short styles tenue, suggesting loss first occurred short-styled individual. In contrast homostylous Primula Fagopyrum, no fixed loss-of-function mutations coding sequences S-linked candidate genes. Instead, gene expression analyses controlled crosses suggest downregulating LtWDR-44 for male self-incompatibility and/or anther height could underlie self-compatibility trigynum. Population 224 whole-genome further demonstrate highly self-fertilizing, exhibits significantly lower diversity genome-wide, experiencing relaxed purifying selection less frequent positive nonsynonymous relative Our shed light advance our understanding common evolutionary transition plants.
