Plant fungal pathogens are an increasing emerging threat as climate change progresses. Sphaeropsis sapinea (syn. Diplodia ), the causal agent of tip blight, is a major pathogen pines forestry and ornamental relevance in Europe worldwide. Here, we combined molecular-based field surveys common-garden setting across elevation gradient with historical records, cultivation-based growth experiments m...

during 2004-2007, a field survey was conducted in different vineyards to determine the fungal pathogens associated with grapevine decline in different provinces of iran including fars,hamedan,isfahan, and kohgiluyeh and boirahmad. twenty-seven isolates of botryosphaeriaceae were recovered from vines showing decline and dieback symptoms only in fars province. based on morphological and cultural ...
The mechanisms and conditions affecting expression of systemic induced resistance (SIR) in pine are not clearly understood. Two hypotheses were tested here: that SIR against a pathogen induced by either a pathogen or an insect involves coordinated shifts in phloem secondary metabolism; and that fertility affects the production of these compounds. To test these hypotheses, a tripartite system wa...
