The chestnut tree is an important forestry species worldwide, as well a valuable food resource. Over recent years, Portugal has shown increasing trend in area, increases production, hinting at the socioeconomic relevance of this agro-forestry species. In study, bioclimatic indices are applied to analyse spatial distribution trees mainland Portugal, namely growing degree days (GDD; 1900–2400 °C)...

to evaluate fertility status and mating type distribution of cryphonectria parasitica, causal agent of chestnut blight in guilan province, four sites in two main growing regions of: shaft (visrud, taleghan and babarekab), and rezvanshahr (doran) were investigated. during the study, fifty four isolates of c. parasitica were examined. c. parasitica isolates were crossed with each of the two matin...

CRISPR/Cas9 has emerged as the most important tool for genome engineering due to its simplicity, design flexibility, and high efficiency. This technology makes it possible induce point mutations in one or some target sequences simultaneously, well introduce new genetic variants by homology-directed recombination. However, this approach remains largely unexplored forest species. In study, we rep...
