The shift from outcrossing to self-fertilization (selfing) is considered one of the most prevalent evolutionary transitions in flowering plants. Selfing species tend share similar reproductive traits morphology and function, such a set called ‘selfing syndrome’. Although genetic basis selfing syndrome has been great interest biologists, knowledge causative genes or mutations was limited until recently. Thanks advances population genomic methodologies combined with high-throughput sequencing technologies, several studies have successfully unravelled molecular for evolution Capsella , Arabidopsis Solanum other genera. Here we first introduce recent research examples that explored loci, responsible traits, as reductions petal size pollen production, are mainly relevant pre-pollination processes. Second, review relationship between interspecific transfer, highlighting findings post-pollination barriers at level. We then discuss emerging view patterns syndrome, pervasive involvement loss-of-function relative importance selection versus neutral degradation.

Recently formed allopolyploid species offer unprecedented insights into the early stages of polyploid evolution. This review examines seven well-studied neopolyploids (we use 'neopolyploid' to refer very recently polyploids, i.e. during past 300 years), spanning different angiosperm families, exploring commonalities and differences in their evolutionary trajectories. Each neopolyploid provides a unique case study, demonstrating both shared patterns, such as rapid genomic phenotypic changes, responses hybridization genome doubling. While previous studies these have improved our understanding polyploidy, significant knowledge gaps remain, highlighting need for further research varied impacts whole-genome duplication on gene expression, epigenetic modifications, ecological interactions. Notably, all spontaneously arisen due human activity natural environments, underscoring profound consequences polyploidization rapidly changing world. Understanding immediate effects polyploidy is crucial not only biology but also applied practices, can lead novel traits, well stress tolerance increased crop yields. Future directions include investigating genetic mechanisms underlying evolution, potential improvement environmental adaptation.

Polyploidy may provide adaptive advantages and is considered to be important for evolution speciation. events are found throughout the evolutionary history of plants, however they do not seem uniformly distributed along time axis. For example, many detected ancient whole-genome duplications (WGDs) cluster around K/Pg boundary (∼66 Mya), which corresponds a drastic climate change event mass extinction. Here, we discuss more recent polyploidy using Arabidopsis as most developed plant model at level entire genus. We review origin allotetraploid species A. suecica kamchatica, tetraploid lineages lyrata, arenosa thaliana, potential advantages. Also, highlight an association between glacial maxima estimated times origins in Arabidopsis. Such might further support link environmental challenge, has been observed now different time-scales both polyploids.

Genome duplication is widespread in wild and crop plants. However, little known about genome-wide selection polyploids due to the complexity of duplicated genomes. In polyploids, patterns purifying adaptive substitutions may be affected by masking owing genes or homeologs as well effective population size. Here, we resequence 25 accessions allotetraploid Arabidopsis kamchatica, which derived from diploid species A. halleri lyrata. We observe a reduction compared with parental species.

Heterostyly is a fascinating adaptation to promote outbreeding and classical paradigm of botany. In the most common type heterostyly, plants either form flowers with long styles short stamens, or stamens. This reciprocal organ positioning reduces pollen wastage promotes cross-pollination, thus increasing male fitness. addition, in many heterostylous species selfing generation unfit progeny due inbreeding depression limited by self-incompatibility system, promoting female The two floral forms are genetically determined S locus as complex supergene, namely chromosomal region containing several individual genes that control different traits, such style stamen length, held together very tight linkage suppressed recombination.
