Differences between the rhizosphere microbiome of Beta vulgaris ssp. maritima—ancestor of all beet crops—and modern sugar beets
The structure and function of the plant microbiome is driven by plant species and prevailing environmental conditions. Effectuated by breeding efforts, modern crops diverge genetically and phenotypically from their wild relatives but little is known about consequences for the associated microbiota. Therefore, we studied bacterial rhizosphere communities associated with the wild beet B. vulgaris...
متن کاملEmergence of gynodioecy in wild beet (Beta vulgaris ssp. maritima L.): a genealogical approach using chloroplastic nucleotide sequences.
Gynodioecy is a breeding system where both hermaphroditic and female individuals coexist within plant populations. This dimorphism is the result of a genomic interaction between maternally inherited cytoplasmic male sterility (CMS) genes and bi-parentally inherited nuclear male fertility restorers. As opposed to other gynodioecious species, where every cytoplasm seems to be associated with male...
متن کاملEffects of fine-scale genetic structure on male mating success in gynodioecious Beta vulgaris ssp. maritima.
Plant mating systems are known to influence population genetic structure because pollen and seed dispersal are often spatially restricted. However, the reciprocal outcomes of population structure on the dynamics of polymorphic mating systems have received little attention. In gynodioecious sea beet (Beta vulgaris ssp. maritima), three sexual types co-occur: females carrying a cytoplasmic male s...
متن کاملGynodioecy in structured populations: understanding fine-scale sex ratio variation in Beta vulgaris ssp. maritima.
Natural selection, random processes and gene flow are known to generate sex ratio variations among sexually polymorphic plant populations. In gynodioecious species, in which hermaphrodites and females coexist, the relative effect of these processes on the maintenance of sex polymorphism is still up for debate. The aim of this study was to document sex ratio and cytonuclear genetic variation at ...
متن کاملWater Stress in Beta vulgaris: Osmotic Adjustment Response and Gene Expression Analysis in ssp. vulgaris and maritima
Beta vulgaris genus comprises wild and cultivated subspecies. The “maritima” subspecies is formed by wild or weedy accessions, well adapted to low-water potential environments; it was previously shown that B. vulgaris ssp. maritima has mechanisms of osmotic adjustment more effective than the cultivated B. vulgaris ssp. vulgaris. The response to a progressive lowering of soil potential was compa...
