Salix viminalis L., a dioecious species, is widely distributed in riparian zones, and flooding is one of the most common abiotic stresses that this species suffers. In this study, we investigated the morphological, anatomical, and physiological responses of male vs. female plants of S. viminalis to ...

Drought stress commonly happens more than once during the life cycle of perennial trees. Stress memory endows better capacity to cope with repeated stresses for plants, while the underlying mechanisms are not fully elucidated. In this study, 2-month-old saplings of two mulberry cultivars (Husang32...

The effect of drought stress on physiological characteristics of three Aceraceae species, namely, Acer palmatum, Acer negundo, Acer palmatum 'Dissectum' were studied, an experiment was conducted using 2-year-old seedlings with polyethylene glycol (PEG 6000) simulated drought stress. Results showed...

Shrubs are pioneer species for ecological restoration in drylands and can promote the growth of herbaceous plants. Knowledge of the water-use characteristics of these revegetated species in different community types is crucial for understanding interspecific and intraspecific interactions and...

Objective: The aim of this study was to explore the changes and responses of hydraulic characteristics of plants under different levels of drought stress, and their ability to repair embolism after rehydration, thereby providing theoretical hydraulic evidences for plants to adapt to drought...

A new whole-plant species of a calamitacean, Palaeostachya guanglongii sp. nov., is described in a volcanic ash bed from the Cisuralian (lower Permian) Wuda Coalfield, Inner Mongolia, North China. It was an approximately 2-3 m high shrub-like plant growing in a peat-forming swamp. It is...

Nitrite-dependent anaerobic methane oxidation (n-damo) acts as a crucial link between biogeochemical carbon and nitrogen cycles. Nevertheless, very few studies have characterized n-damo microorganisms in high-latitude permafrost regions. Therefore, this study investigated the vertical distribution...

A new species Pertusaria wui is described from bamboo in Yunnan Province, China. Diagnostic characters include a thin, shiny, off-white, continuous and crustose thallus, numerous (mostly conical) verrucae with punctiform ostioles, uniseriate ascospores of 47.5-62.5 × 25-30 μm, 8-spored asci, and...

The petiole, which connects the leaf to the stem, is an important vascular pathway of water and nutrients in plants. In order to evaluate the water transporting capacity and transpiration resistance of petiole among different mulberry varieties, the anatomical characteristics of petioles in...

Objective: In this study, we examined Agriophyllum squarrosum, Corispermum pubemlum, Chenopodium arislatum, and Sophora alapecuroides in the Mu Us Desert of northwestern China to explore the ability of leaf condensate absorption and their physiological responses to water. Method: We determined...
