Abstract:

•Whole genome sequencing analysis reveal the first case of natural hybridization in Rhododendron subgenus Tsutsusi in China.•Most examined Rhododendron strigosum plants (putatively hybrid origin) were F1s, indicating nearly complete reproductive isolation between the two parental species.•We further revealed the rare formation of F2s after detecting seedlings from seeds of ex-situ conserved Rhododendron strigosum under natural pollination.•Rhododendron hypoblematosum had both the highest number of homozygous deleterious mutations and the highest ratio of homozygous deleterious mutations to synonymous mutations, exceeding that of the F1s.

Hybrid Zones

Hybrid Zones

Hybrid zones are narrow regions where two closely related species interact, mate, and produce hybrids. Relative to either parent species, hybrids may possess distinct phenotypic or genetic differences that impact their survival and reproductive success. The genetic variances introduced by hybridization influence species diversity and speciation processes within the hybrid zone.

Genetics of Speciation

Genetics of Speciation

Speciation is the evolutionary process resulting in the formation of new, distinct species—groups of reproductively isolated populations.

Evolutionary Relationships through Genome Comparisons

Evolutionary Relationships through Genome Comparisons

Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

Formation of Species

Formation of Species

Speciation describes the formation of one or more new species from one or sometimes multiple original species. The resulting species are discrete from the parent species, and barriers to reproduction will typically exist. There are two primary mechanisms, speciation with and without geographic isolation—allopatric and sympatric speciation, respectively.
