The rapid conversion of tropical rainforests into monoculture plantations of rubber (Hevea brasiliensis) in Southeast Asia (SEA) necessitates understanding of rubber tree physiology under local climatic conditions. Frequent fog immersion in the montane regions of SEA may affect the water and carbon ...

In order to explore the effect of drought stress on the endogenous hormones content of potted seedlings of Ulmus pumila 'Jinye', three treatments, namely control (CK), mild drought stress (MD), and severe drought stress (SD) were set up by using potted seedlings of U. pumila 'Jinye' as test...

The SEVEN IN Absentia (SINA), a typical member of the RING E3 ligase family, plays a crucial role in plant growth, development and response to abiotic stress. However, its biological functions in oil crops are still unknown. Previously, we reported that overexpression of AtSINA2 in Arabidopsis...

Tetraploid poplar plants were induced by colchicine from tissue-cultured shoots; the induction efficiency varied with colchicine concentration. Morphologically, induced tetraploid plants were significantly distinguishable from diploid plants; their leaves were larger, thicker, and rounder, with...

Cleistocalyx operculatus (Roxb.) Merr. is a waterlogging-tolerant terrestrial plant species with important economic value. In this study we explored the effect of the exogenous growth hormone indoleacetic acid (IAA) and stress hormone abscisic acid (ABA) on waterlogging tolerance of C. operculatus. ...

Crassulacean acid metabolism (CAM) plants exhibit elevated drought and heat tolerance compared to C₃ and C₄ plants through an inverted pattern of day/night stomatal closure and opening for CO₂ assimilation. However, the molecular responses to water-deficit conditions remain unclear in obligate CAM...

The Himalayas with dramatic elevation gradient is one of the global biodiversity hotspots. Although origin of biodiversity of the Himalayas is of great concern, the speciation process within the Himalayas is poorly known. Roscoea within the Himalayas serve as a good model system to test the...

Salvia miltiorrhiza Bunge (Danshen) is an important traditional Chinese medicine herb. This study aimed to investigate the drought-responsive metabolic profiling in S. miltiorrhiza using gas chromatography time-of-flight mass spectrometry (GC-TOFMS) analysis. Fifty day-old S. miltiorrhiza seedlings ...

It is important to evaluate nitrogen use efficiency and nitrogen tolerance of trees in order to improve their productivity. In this study, both were evaluated for 338 Populus deltoides genotypes from six provenances. The plants were cultured under normal nitrogen (750 μM NH₄NO₃) and low nitrogen (5 ...

The mechanisms responsible for biodiversity formation and maintenance are central themes in biodiversity conservation. However, the relationships between community assembly, phylogeny, and functional traits remain poorly understood, especially following disturbance. In this study, we examined...
