Plant mitochondrial genome (mitogenome) has crucial functions underpinning survive, development, and reproduction of organisms. However, the complete mitogenomes have been far less assembled and annotated than plastomes and even nuclear genomes in plants, due to their highly frequent and long repeat sequences and genomic structural variations. Thes...

Adaptive radiation is usually triggered by great in situ or ex situ environmental changes. How an adaptive radiation occurs on lands and how species richness relates to morphodisparity have been a major focus of evolutionary biology. Petrocodon , diversified in the southeastern Qinghai–Tibet Plateau (QTP), represents an ideal model to address these...

The genus Petrocodon is renowned for its remarkably diverse floral morphology, exhibiting a high level of disparity compared to most genera within Gesneriaceae. In this study, we present a detailed description and illustration of Petrocodon gracilis T. Ding & B. Pan, a new species with unique floral features that is native to Guangxi, China. This s...

The genus Didymocarpus Wall is a core group of the subfamily Didymocarpoideae in Gesneriaceae with a complex taxonomic history. It has long been controversial to delimit Didymocarpus and its allies. We conducted phylogenetic reconstructions with high-density sampling of Didymocarpus and related genera by using four nuclear ribosomal DNAs (external...

Metapetrocosmea W. T. Wang and Deinostigma W. T. Wang & Z. Y. Li were originally monotypic with M. peltata (Merr. et Chun) W. T. Wang and D. poilanei (Pellegr.) W. T. Wang & Z. Y. Li, respectively. Recent molecular phylogenetic research expanded Deinostigma to include several species previously transferred from Chirita D. Don to Primulina Hance. Ho...

Primulina fangdingii, a species of Gesneriaceae new to science from Guangxi, China, is corroborated by both morphological and molecular evidence. The new species is similar to P. longzhouensis in leaf shape and size, but is easily distinguished from the latter by its adaxially glabrous leaf blades, yellow corolla with reddish inner surface and yell...

Chirita umbrophila is a species endemic to Yunnan, China, and its exact systematic position remains a mystery since it was treated as a species with uncertain generic affiliation in the taxonomic revision of Chirita in 1985. In the present study, the phylogenetic relationships between C. umbrophila and its allied species were inferred using two nuc...

Didymocarpus cordifolius, a new species of Gesneriaceae from southern Yunnan Province, China is described and illustrated. The new species is morphologically similar to D. silvarum and D. margaritae, but can be readily distinguished by its short petioles with both glandular and eglandular hairs, pale purple corolla, hairy anthers, and ovary and sty...

A new species of Gesneriaceae, Primulina clausa P.W.Li & M.Kang was described, which occurs in the karst areas of northern Guangxi Zhuang Autonomous Region of China. The new species is morphologically similar to P. obtusidentata (W.T.Wang) Mich.Möller & A.Weber, but can be readily distinguished by its short and prostrate peduncle, slightly unfolded...

A widely held hypothesis in evolution is that adaptive specialization constrains the potential direction of future evolutionary change and thus may be irreversible, i.e., the Dollo's law. However, this hypothesis has long been subject to debate in evolutionary biology. Floral specialization is intriguing as it is usually linked to reproductive isol...

Unlike most crops, which were domesticated through long periods of selection by ancient humans, horticultural plants were primarily domesticated through intentional selection over short time periods. The molecular mechanisms underlying the origin and spread of novel traits in the domestication process have remained largely unexplored in horticultur...

Leucine-rich repeat receptor-like protein kinases (LRR-RLKs) are the largest group of receptor-like kinases, which are one of the largest protein superfamilies in plants, and play crucial roles in development and stress responses. Although the evolution of LRR-RLK families has been investigated in some eudicot and monocot plants, no comprehensive e...

Phylogeny of LRR-RLK genes in Amborella trichopoda and Arabidopsis thaliana. This phylogenetic tree based on kinase domain sequence was constructed by the Maximum Likelihood method.

The full name of 94 LRR-RLK proteins identified in the Amborella trichopoda genome.

Petrocodon hunanensis, a new species of Gesneriaceae from limestone area in Hunan Province, China, is described and illustrated. The new species is morphologically similar to Petrocodon coriaceifolius, but readily differs from the latter one in the growth form with terrestrial stems and distinct internodes, both surfaces of leaf densely with white...
