Altai (also named Altay in China) Mountain Country (Mountain System) is a unique natural region, located on the border between different floristic regimes of the Boreal and ancient Mediterranean sub-kingdoms, where distribution of plant species is actually limited. It is known to have sufficient endemic floral biodiversity in the Northern Asia. Many plants of Altai Mountain System need effectiv...
An in vitro regeneration protocol through stem callus culture has been standardized for the medicinal climber Clematis gouriana. The explant induced callus on MS-medium supplemented with 0.5 to 1.5 mg l BAP and 0.1 to 0.5 mg l NAA. The optimized callus induction occurred at the concentration of 1.0 mg l BAP and 0.3 mg l NAA. After initiation of callus, it was immediately transferred to MS mediu...
Numerous studies have examined relationships between primary production and biodiversity at higher trophic levels. However, altered production in plant communities is often tightly linked with concomitant shifts in diversity and composition, and most studies have not disentangled the direct effects of production on consumers. Furthermore, when studies do examine the effects of plant production ...
Plant growth can be affected by soil bacteria. In turn, plants are known to influence soil bacteria through rhizodeposits and changes in abiotic conditions. We aimed to quantify the phylotype richness and relative abundance of rhizosphere bacteria that are actually influenced in a plant species-specific manner and to determine the role of the disproportionately large diversity of low-abundance ...
