populus tristis/proline

Proline-rich protein (PRP) is a plant cell wall associated protein. Its distinct patterns of regulation and localization studied in a number of plants indicate that it may play important roles in growth and development. However, the mechanism of how these genes control secondary cell wall

Excess salt in the soil solution affects the plant either through osmotic or ionic effects. Poplar trees, as fast growing pioneer tree species, are thought to be potential suitable candidates for afforestation on saline soils. Osmotic and oxidative stress induced by salinity could be reduced by the

A study has been made of the influence of separate and simultaneous action of SO(2), NaCl and polyethylene glycol 8000 (PEG) on leaf injuries and free proline content of two poplar cuttings, Populus 'Robusta' and P. 'Hybrida 275', at an optimum (+15 degrees C), a lowered (+3 degrees C) and an

Plantlets of Populus yunnanensis Dode were examined in a greenhouse for 48 h to analyze their physiological and proteomic responses to sustained heat, drought, and combined heat and drought. Compared with the application of a single stress, simultaneous treatment with both stresses damaged the

The salinity stress inhibits the growth of Populus euphratica (P. euphratica), and the extent of inhibition tends to increase with a rise of salt concentration while the net photosynthesis rate, stomatal conductance, transpiration rate, and internal CO2 concentration are seen to decline with

Dioecious plants show sexually different responses to environmental stresses. However, little is known about the dimorphic morphological and physiological responses to soil pollution. To investigate sex-related adaptive responses of Populus yunnanensis seedlings when exposed to excess zinc (Zn),

In recent years, pollution by heavy metals (HM) has become an increasingly serious problem in forest ecosystems, making their remediation a primary research focus in China. Poplars are ideal candidates for phytoremediation because of their great commercial value, ability to produce large biomass,

We used the dioecious tree, Populus cathayana, as a model species to study plants' physiological and biochemical responses to copper (Cu) stress, exogenous putrescine (Put) treatment and their interaction. Although males accumulated higher Cu concentrations in leaves than did females under Cu

We investigated the impact of drought and arbuscular mycorrhizal (AM) fungi on the morphological structure and physiological function of shoots and roots of male and female seedlings of the dioecious plant Populus cathayana Rehder. Pot-grown seedlings were subjected to well watered or water-limiting

The complete amino acid sequence of the plastocyanin from the green alga Enteromorpha prolifera has been determined by Edman degradation of the intact molecule and fragments produced by enzymatic cleavage of the polypeptide chain with chymotrypsin, Staphylococcus aureus protease, proline-specific

This study aimed to improve current understanding on ethylene-insensitive 3-like (EIL) members, least explored in woody plants such as poplar (Populus trichocarpa Torr. & Grey). Herein, seven putative EIL members were identified in P. trichocarpa genome and were roughly annotated either as EIN3-like

We investigated the impact of arbuscular mycorrhizal fungi (AMF) on the morphology and physiology of two genders of the typical dioecious plant Populus cathayana under salt stress. We conducted a pot experiment containing seedlings of the two genders that were subjected to salt or non-salt and

The crystal structure of Hg(II)-plastocyanin has been determined and refined at a resolution of 1.9 A. The crystals were prepared by soaking crystals of Cu(II)-plastocyanin from poplar leaves (Populus nigra var. italica) in a solution of a mercuric salt. Replacement of the Cu(II) atom in

Populus species are very effective in remediation of contaminants. Polybrominated diphenyl ethers (PBDEs) are commonly used as flame retardants and are known to be persistent environmental pollutants. Numerous studies have shown that PBDEs are rising in human tissues and biota. 4-Monobrominated
