The question of the stability of distribution ranges of species is fundamental in evolutionary ecology. There are two theoretical frameworks, local adaptation and metapopulation dynamics, to solve this question. For example, Kirkpatrick and Barton (1997) provided one of the first evolutionary models for a species on a gradient of environmental conditions. The metapopulation framework proposed b...
Both carbon monoxide (CO) and nitric oxide (NO) play fundamental roles in plant responses to environmental stress. Glutathione (GSH) homeostasis, achieved through the activity of the glutathione-ascorbate cycle, regulates cellular redox status to avoid the damage of reactive oxygen species (ROS) or reactive nitrogen species (RNS) to cellular components. Most recalcitrant seeds are sensitive to ...
High temperature and high humidity typically are characterized as independent abiotic stress conditions. An understanding of the mechanisms underlying plant tolerance to high temperature and humidity may facilitate the development of cultivars adaptable to warm or humid regions.
HU Xiangyang’s group from Kunming Institute of Botany applied physiological and comparative proteomics to inves...
In 1886, Nylander published the lichen species Bryoria divergescens (Nyl.) Brodo & D. Hawksw. based on a small holotype specimen less than 2 cm long, it was collected by P. J. M. Delavay in 1885 from Yunnan Dali (H-Nyl. 35972, Holotype).
Tea is the most widely consumed beverage plant in the world. Because of the likely presence in wild species of traits desirable for plant breeding, it is important to conserve the genetic resources. However, tea seeds can’t be long-term stored at conventional seed bank temperature due to the sensitive of desiccation and low temperature. The assignment of tea seed storage biology has been the s...
Matsutake mushrooms (Tricholoma matsutake) are highly prized, seasonal gourmet items for the Japanese market. Yunnan Province contributes nearly 1/3 of the total matsutake production sold in Japan with an annual benefit of more than 40 million US dollars. In the communities harvesting matsutake in Yunnan, household income generated from matsutake can be up to 80%. However, there is an observed ...
Arundinarieae is a tribe comprising about 600 taxa in 32 genera and belongs to the family Poaceae, subfamily Bambusoideae. Bamboos in this tribe are mainly distributed in the temperate and subtropical regions of Africa, Asia, and southeastern North America, with East Asia as the center of diversity with more than 500 species. Most of these species are important ecological components of the subt...
April 19, the State Forestry Administration of New Plant Variety Protection Office organized experts to progress the site investigation for four candidate new vatieties of Michelia which were nurtured and applied by Kunming Institute of Botany (KIB) and were proosed to be named 'Yunrui', 'Yunxia', 'Yunxin' and 'Yunxing'.
After hearing the report about the breeding process for the four new v...
The Mekong River is the longest watercourse in Southeast Asia. Although China has an extensive hydropower program underway on the Upper Mekong, as yet there are no dams on the river’s lower mainstream. However, as many as 12 additional projects, which would generate substantial energy and wealth especially for Cambodia and Laos, are currently in the proposal stage for the Lower Mekong (LM).
