Chrysophorte cubensis induced canker occurs in nearly all tropical and subtropical regions where eucalypts are planted, causing losses in both wood quality and volume productivity, especially so in the warmer and more humid regions of Brazil. The wide inter and intra-specific genetic variability of resistance to canker among Eucalyptus species facilitates the selection of resistant plants. In t...

The abundance of freshwater snails in two rural sites of Pinar del Río, Cuba, which harbor Pseudosuccinea columella susceptible and resistant to miracidia of Fasciola hepatica was followed for one year. Susceptible snails were found in the most anthropic site (IPA) whereas the resistant population inhabited the most preserved one (El Azufre). Only two snail species coexisted with P. columella a...

Landscape features impact gene flow and the spatial patterns of genetic variation between populations a species. Because many Magnoliaceae species occur in fragmented highly disturbed landscapes, family provide an excellent model for landscape studies. This research focuses on subspecies subpopulations Magnolia cubensis aims to: (1) compare diversity different their subpopulations, (2) search d...

Commercial plantations of Eucalyptus species have been established in Malaysia, especially during the past 10 years, with aim sustaining supply wood and timber products for industrial use Malaysia. As part an assessment fungal diseases affecting four regions including Kelantan, Pahang, Sabah, Selangor, stem canker disease was discovered to be a widespread infecting This study aimed identify fun...

Pathogenesis of Pseudoperonospora cubensis causing downy mildew of cucumber resulted in changes in the metabolic processes within cucumber leaves including the transpiration rate. Due to the negative correlation between transpiration rate and leaf temperature, digital infrared thermography permitted a non-invasive monitoring and an indirect visualization of downy mildew development. Depending o...

Zhang, S. P., Liu, M. M., Miao, H., Zhang, S. Q., Yang, Y. H., Xie, B. Y., Wehner, T. C., and Gu, X. F. 201_. Chromosomal mapping and QTL analysis of resistance to downy mildew in Cucumis sativus. Plant Dis. 9_:XXXX-XXXX. Downy mildew of cucumber (Cucumis sativus L.), caused by Pseudoperonospora cubensis (P. cubensis), is a major foliar disease worldwide. The cucumber inbred lines K8 (resistant...
