Restoration of kelp forests typically relies on transplanting sporophylls to new locations and has limited application in regions with low remnant cover. Cultivated requires fewer is a potential alternative sustainable source transplants for large-scale restoration projects. Naturally sourced fertile sporophylls, however, are still required as “seed” stock cultivation practices, thus optimizing...

ABSTRACT- The effects of inoculum density and temperature on the disease intensity of Phytophthoraparsiana on almond seedlings were investigated. Almond seeds (Rabie and Kaghazi cultivars) were placed in moist vermiculite at 4°C for 45 days. Germinated seeds were sown in a soil: sand mixture (2:1 v/v) and grown in greenhouse (18°C-25°C). One-month-old seedlings were transferred from the greenho...

Many fungi have been identified as pathogens of marine algae. Among them, Chytridiomycota revealed relatively highly abundant, but much the diversity known within these groups is almost entirely based on environmental sequencing data. Here, we present a novel chytridiomycete genus and species, characterized by light microscopical observations, ultrastructure, molecular phylogenetic analysis par...

The European chestnut (Castanea sativa) is threatened by the hemibiotrophic oomycete Phytophthora cinnamomi, causal agent of ink disease. Chestnut species have different susceptibility levels to P. with Asian (C. crenata; C. mollissima) exhibiting highest level resistance. A histological approach was used study responses exhibited susceptible and resistant genotypes characterizing early stages ...

Refugia are habitats where species can survive or retreat to during environmental disturbances. One key assumption of that constitute refugia is they may assist in the persistence impacted populations through provision reproductive propagules. This “reseeding” hypothesis assumes demographic connectivity exists between and habitats. We tested this for kelp Ecklonia radiata, a temperate marine fo...

Faba bean gall (FBG) is a devastating disease of faba (Vicia faba) in Ethiopia. Studies were undertaken first to compare and contrast similarities between FBG symptoms morphology Ethiopia with those reported earlier China and, secondly, identify definitively the causal agent, previously considered as Olpidium viciae, through molecular studies. Morphological studies confirmed an epibiotic phase ...

Abstract Aegagropila linnaei is a unique freshwater green alga that develops into spherical aggregations known as “lake balls”, “Cladophora balls” or “Marimo”. Loss of this species progressing globally, and there concern over threats its conservation. As part the study which aims to conserve endangered species, zoosporogenesis A. in Lake Akan, designated Special Natural Monument Japan, was inve...
