Physalacria peck is the type genus of the family Physalacriaceae in Agaricales, and is characterized by the physalacrioid basidiomata with a bubble-like head (usually less than 6 mm in wide) and a stuffed stipe (≤ 1 cm in height).
One of the main goals of conservation biology is to understand the factors shaping variation in biodiversity across the planet. This understanding is critical for conservation planners to be able to develop effective conservation strategies. Although many studies have focused on species richness and the protection
of rare and endemic species, less attention has been paid to the protection of th...
Changing climate is likely to impact on both tree species and agroforestry systems in a variety of ways. A multi-model ensemble approach based on ecological niche modelling was used to understand the impact of climate on distribution of agroforestry trees in Yunnan Province of China.
Urticaceae is a family with more than 2000 species, which contains remarkable morphological diversity. It has undergone many taxonomic reorganizations, and is currently the subject of further systematic studies. To gain more resolution in systematic studies and to better understand the general patterns of character evolution in Urticaceae, based on our previous phylogeny including 169 accession...
Thrombotic disease is one of the major causes of human death. Unfortunately, almost all anticoagulants currently used could cause severe risk of bleeding. Because intrinsic coagulant factors are necessary for thrombosis but not required for hemostasis, developing new anticoagulants which selectively inhibit components of the intrinsic coagulant factors has become a hot and challenging focus in ...
Natural hybridization in plants is universal and plays an important role in evolution. Based on morphology it has been presumed that hybridization occurred in the genus Buddleja, though genetic studies confirming this assumption have not been conducted to date. The two species B. crispa and B. officinalis overlap in their distributions over a wide range in South-West China, and we aimed to prov...
palaeoenvironmental information in geological time and also a baseline reference for understanding future climatic change. The inverse relationship between atmospheric CO2 partial pressure (pCO2) and stomatal frequency in many species of plants has been widely used to estimate palaeoatmospheric CO2 (palaeo-CO2) levels. In contrast to the negative correlations detected for most other species tha...
Heterostyly is a conspicuous floral polymorphism in which non-random mating is usually enforced by a strong diallelic self-incompatibility system that ensures intermorph mating by preventing self and intramorph mating. Populations of heterostylous species contain either two (distyly) or three (tristyly) floral morphs that differ reciprocally in the relative positions of stigmas and anthers, a c...
Vitis vinifera ( grape ) is one of the most economically significant fruit crops in the world. The availability of the recently released grape genome sequence offers the opportunity to identify and analyze some important gene families in this species. Subtilases are a group of subtilisin-like serine proteases that are involved in many biological processes in plants. However, no comprehensive st...
