Phytophthora niederhauserii sp. nov., a polyphagous species associated with ornamentals, fruit trees and native plants in 13 countries.
A non-papillate, heterothallic Phytophthora species first isolated in 2001 and subsequently from symptomatic roots, crowns and stems of 33 plant species in 25 unrelated botanical families from 13 countries is formally described here as a new species. Symptoms on various hosts included crown and stem rot, chlorosis, wilting, leaf blight, cankers and gumming. This species was isolated from Austra...
متن کاملPhylogeny of Phytophthora and Phytopythium species associated with rice in Fars province (Iran)
In order to investigate the Oomyceteous species of the rice paddy fields of Fars province (Iran), during 2013–15, infected roots and crowns together with soil around seedlings and irrigation water were sampled. Based on the morphological, morphometric and physiological studies along with phylogenetic analyses of internal transcribed spacer sequences based on neighbor joining method, two Phytoph...
متن کاملScheduling Woody Plants for Production and Harvest
Growth characteristics and marketing of woody ornamentals prevent crop scheduling common in floriculture crops. However, many tasks in the production of woody ornamentals require coordination with the season and/or physiological state of the species. Since most woody ornamental nurseries produce many species or cultivars, a variety of tasks occur concurrently. This review highlights the major t...
متن کاملPhytophthora ramorum: a pathogen with a remarkably wide host range causing sudden oak death on oaks and ramorum blight on woody ornamentals.
UNLABELLED Phytophthora ramorum is an oomycete plant pathogen classified in the kingdom Stramenopila. P. ramorum is the causal agent of sudden oak death on coast live oak and tanoak as well as ramorum blight on woody ornamental and forest understorey plants. It causes stem cankers on trees, and leaf blight or stem dieback on ornamentals and understorey forest species. This pathogen is managed i...
متن کاملMolecular Markers for Identification of P. ramorum and Other Phytophthora species From Diseased Tissue
Molecular techniques have been developed for detection and identification of P. ramorum and other Phytophthora species that are based on the mitochondrially encoded sequences. One technique uses a Phytophthora genus specific primer to determine if a Phytophthora species is present, followed by a nested amplification with species-specific primers to determine if the pathogen is P. ramorum or one...
