Evolution of Apocarpy in Alismatidae Using Phylogenetic Evidence from Chloroplast rbcL Gene Sequence Data
The apocarpous groups in the monocotyledons are mainly concentrated in the subclass Alismatidae. The molecular phylogeny of Alismatidae based on analysis of chloroplast rbcL gene sequence data serves… Expand
Pollination ecology, breeding system, and conservation of Caldesia grandis (Alismataceae), an endangered marsh plant in China
Caldesia grandis Samuelsson is an endangered wetland herb on the brink of extinction in the vast area of Mainland China, which holds close to one eighth of the world’s vascular plant species. The… Expand
Reproductive consequences of interactions between clonal growth and sexual reproduction in Nymphoides peltata: a distylous aquatic plant.
Distyly is a sexual polymorphism in which plant populations contain two floral morphs differing in morphology and physiology. The dimorphism serves to promote animal-mediated cross-pollination… Expand
Resource limitation and pollen source (self and outcross) affecting seed production in two louseworts, Pedicularis siphonantha and P. longiflora (Orobanchaceae)
Two animal-pollinated hermaphrodite plants, Pedicularis siphonantha and P. longiflora, have been used to investigate factors limiting seed production in natural populations. To evaluate the potential… Expand
Genotypic diversity and genetic structure of populations of the distylous aquatic plant Nymphoides peltata (Menyanthaceae) in China
Nymphoides peltata is a distylous aquatic plant. In order to explore the relative importance of clonal growth and sexual reproduction within populations and also to reveal the origin of the commonly… Expand

Cytochrome P450 2C9 (CYP2C9) is a geneticly polymorphic enzyme responsible for the metabolism of some clinically important drugs. CYP2C9*13 is an allele identified in a Chinese poor metabolizer of… Expand
Reproductive isolation of two sympatric louseworts, Pedicularis rhinanthoides and Pedicularis longiflora (Orobanchaceae): how does the same pollinator type avoid interspecific pollen transfer?
To study the isolation mechanism of two commonly intermingled louseworts, Pedicularis rhinanthoides and Pedicularis longiflora, pollination biology in three mixed populations with the two species was… Expand
The presence of co-flowering species facilitates reproductive success of Pedicularis monbeigiana (Orobanchaceae) through variation in bumble-bee foraging behaviour.
Background and Aims The presence of co-flowering species can alter pollinator foraging behaviour and, in turn, positively or negatively affect the reproductive success of the focal species. Such… Expand
TEMPORAL FLORAL SEX ALLOCATION IN PROTOGYNOUS AQUILEGIA YABEANA CONTRASTS WITH PROTANDROUS SPECIES: SUPPORT FOR THE MATING ENVIRONMENT HYPOTHESIS
We tested one of the predictions of Brunet and Charlesworth (1995) that relative floral sex allocation will vary temporally with the mating environment and that the form of dichogamy (protandry vs.… Expand
Variations of floral traits among different life forms illustrate the evolution of pollination systems in Potamogeton species from China
Abstract Four leaf morpha groups (floating-leaved, submerged broad-leaved, submerged linear-leaved and filiform-leaved) and three inflorescences type groups (erect, facultative floating and floating)… Expand
