eucalyptus cyanophylla/proline

The present study aimed to explore the tolerance potential of Cd, Pb and Cu and physiological alterations in two common tree species growing in Minia governorate (Egypt) namely: Eucalyptus globulus and Ficus nitida and to investigate the leaf features [leaf area (LA) and specific leaf

The habitat of Cryptococcus neoformans var. gattii is not fully known in Mexico. We investigated the relationship of the yeast with Eucalyptus camaldulensis soil in three main Avenues of the city. A total of 135 trees of the species E. camaldulensis, were selected. Samples were taken in duplicate

Cell suspension cultures were initiated from two clones of Eucalyptus gunnii differing by their frost resistance.During cold treatments viability of the individual cell lines and of their protoplasts was correlated to the degree of frost resistance of the starting clones.Moreover, at moderate

The present study evaluated eight genotypes of river red gum (Eucalyptus camaldulensis Dehnh.) and a hybrid (E. camaldulensis × E. urophylla) for mannitol-induced water deficit (WD) under photoautotrophic conditions using multivariate cluster analysis. Shoot height, plant dry weight, and chlorophyll

BACKGROUND Eucalyptus grandis is an important commercial forestry species in South Africa. Little is known about its response (which is both drought and cold sensitive) to cold exposure and subsequent drying. OBJECTIVE The study was to investigate the responses of E. grandis in vitro shoots to cold

The study on the physiological bases of the shade-tolerance of Dactylis glomerata, Lolium perenne, and Hemarthria compressa inter-cultivated in Eucalyptus grandis forests with different canopy densities showed that with increasing canopy density, the light saturation point (LSP), light compensation

About 1000 salt-responsive ESTs were identified from an extreme halophyte Salicornia brachiata. Among these, a novel salt-inducible gene SbSLSP (Salicornia brachiata SNARE-like superfamily protein), showed up-regulation upon salinity and dehydration stress. The presence of cis-regulatory motifs

Eucalyptus grandis is the most widely planted tree species worldwide and can face severe drought during the initial months after planting because the root system is developing. A complete randomized design was used to study the effects of two water regimes (well-watered and water-stressed) and

Two of the ways in which plants cope with water deficits are stomatal closure and "osmotic adjustment". We sought to assess the contributions of these processes to maintenance of leaf hydration in field-grown, 7-year-old Eucalyptus marginata. Plants were exposed to their normal summer drought

We compared the metabolic responses of leaves and roots of two Eucalyptus globulus Labill. clones differing in drought sensitivity to a slowly imposed water deficit. Responses measured included changes in concentrations of soluble and insoluble sugars, proline, total protein and several antioxidant

Plant growth-promoting rhizobacteria (PGPR) are widely used to improve plant nutrient uptake and assimilation and soil physicochemical properties. We investigated the effects of bacterial (Bacillus megaterium strain DU07) fertilizer applications in a eucalyptus (clone DH32-29) plantation in Guangxi,

Studies of water stress commonly examine either gas exchange or leaf metabolites, and many fail to quantify the concentration of CO₂ in the chloroplasts (C(c)). We redress these limitations by quantifying C(c) from discrimination against ¹³CO₂ and using gas chromatography-mass spectrometry (GC-MS)

There is emerging evidence for the phytotoxicity of terrestrial dissolved organic matter (DOM), however its sources, transformations and ecological effects in aquatic ecosystems are poorly understood. DOM characterization by Nuclear Magnetic Resonance (NMR) spectroscopy has typically involved

The ecology of Cryptococcus neoformans var. gatti is restricted to tropical and subtropical areas whereas C. neoformans var. neoformans is cosmopolitan. Perú is a country with three different well defined geographic areas, some of them have the conditions for the presence of the variety gattii. In
