Abiotic stressors such as drought and heat predispose chickpea plants to pathogens of key importance leading to significant crop loss under field conditions. In this study, we have investigated the influence of drought and high temperature on the incidence and severity of dry root rot disease...

The effects of drought stress, Phytophthora cinnamomi infection and their interaction on water relations and growth were examined for 28 days on two year-old potted trees of Eucalyptus obliqua (L'Hér.). There were significant effects of drought stress on plant photosynthesis, stomatal conductance,...

Introduction: Drought stress is the most influential factors affecting crop yield particularly in irrigated agriculture in arid and semiarid regions. Drought, being the most important environmental stress, severely impairs plant growth and development, limits plant production and the performance of ...

Charcoal canker of oak, which has recently increased in southern Iran, could pose a serious threat to the entire forest ecosystem in the near future. In addition, it seems that climate change and its consequences, such as drought in the southern regions of Iran, have exacerbated this phenomenon....

The effects of whole soil biotic communities on plants is a result of positive and negative interactions from a complex suite of mutualists and pathogens. However, few experiments have evaluated the composite effects of whole soil biotic communities on plant growth and disease resistance. We...

The decrease in the rate of inflow and outflow of water-and thereby the uptake of plant nutrients as the result of Huanglongbing (HLB or citrus greening)-leads to a decline in overall tree growth and the development of nutrient deficiencies in HLB-affected citrus trees. This study was conducted at...

Erysiphe species (powdery mildews) on Corylus and Ostrya hosts (Betulaceae subfam. Coryloideae) in Asia and North America are widespread pathogens on these economically and ecologically valuable nut crops. An improved understanding of their phylogeny and taxonomy is of ecological and applied...

This report presents information on all aspects of the biology, ecology and invasion behaviour of Rhododendron ponticum L., particularly R. ponticum subsp. baeticum (Boiss. & Reut.) Hand.-Mazz. The main topics presented are: taxonomy, distribution, history of introduction and spread, ecology,...

Healthy forests are essential to human life because they provide food, energy, and other benefits including carbon sequestration. The objective of this study was to assess the forests health status in Mediterranean ecosystems, specifically, arid to semi-arid. Four forest reserves directed by Royal...

Three new species of Hypoxylon (Hypoxylaceae, Xylariales) are described based on a polyphasic approach that included morphological examination, molecular phylogeny and chemotaxonomic studies of specimens collected in Panama. Specifically, we compared the sexual morph (stromata, asci, and...
