“…Examples of oomycete pathogens causing severe crop losses and human hardships include the potato late blight caused by Phytophthora infestans in the 1840s that resulted in Irish famine, and jarrah dieback in Australia caused by Phytophthora cinnamomi that infected over four hundred plant species belonging to forty different families, with the most severely affected belonging to the families Proteaceae, Leguminoseae, Epacridaceae, Myrtaceae and Xanthorrhoeaceae. [31,32]. In contrast, although Pythium spp.…”

“…In addition, several genetic markers are available for P. boehmeriae including Cox 2, Nad 9, Rps 10, and Sec Y. Similarly, signature sequences for P. capsici was found at Cox 1, Cox 2, Nad 1 and Nad 5 genes [32,37]. Indeed, Kulik et al recently introduced detailed mitochondrial gene markers for detecting various plant pathogenic fungi and oomycetes, such as Cox 2 for Fusarium culmorum, Cox 1 and Cox 2 for P. ramorum, Cob for Fusarium graminearum s.s., atp9 for Phytophthora species [77].…”

“…In addition, it can cause gummosis and canker, brown rot (fruit) and root rot diseases in non-fiber crops and tress such as black wattle, citrus, black button, Mexican yellow pine, etc. [32]. Phytophthora cinnamomi causes a root rot or dieback and is one of the world's most invasive pathogens, so far reported in more than 70 countries around the world.…”

“…Among these pathogens, P. boehmeriae was the most prevalent agent for cotton blight [31]. Interestingly, P. boehmeriae can also cause ramie blight [31,32]. Similarly, Phytophthora palmivora could cause windmill palm bud and root rot and is a pathogen of cotton causing cotton blight [31,42].…”

Fiber crops are an important group of economic plants. Traditionally cultivated for fiber, fiber crops have also become sources of other materials such as food, animal feed, cosmetics and medicine. Asia and America are the two main production areas of fiber crops in the world. However, oomycete diseases have become an important factor limiting their yield and quality, causing devastating consequences for the production of fiber crops in many regions. To effectively control oomycete pathogens and reduce their negative impacts on these crops, it is very important to have fast and accurate detection systems, especially in the early stages of infection. With the rapid development of molecular biology, the diagnosis of plant pathogens has progressed from relying on traditional morphological features to the increasing use of molecular methods. The objective of this paper was to review the current status of research on molecular diagnosis of oomycete pathogens on fiber crops. Our search of PubMed identified nearly 30 species or subspecies of oomycetes on fiber crops, among which the top three species were Phytophthora boehmeriae, Phytophthora nicotianae and Pythium ultimum. The gene regions that have been used for molecular identifications of these pathogens include the internal transcribed spacer (ITS) regions of the nuclear ribosomal RNA gene cluster, and genes coding for translation elongation factor 1α (EF-1α) and mitochondrial cytochrome c oxidase subunits I and II (Cox 1, Cox 2), etc. We summarize the molecular assays that have been used to identify these pathogens and discuss potential areas of future development for fast, specific, and accurate diagnosis of oomycetes on fiber crops.

“…The only other genome sequence from a Clade 3 species is from Phytophthora pluvialis ( Studholme et al 2016 ). Another globally distributed species is Phytophthora boehmeriae (Clade 10) which not only causes disease on trees such as black wattle ( Acacia mearnsii ), but also crops such as cotton and chili ( Chowdappa et al 2014 ; Santos 2016 ; Wang et al 2020 ). Phytophthora Clade 10 contains few species ( Yang et al 2017 ).…”

Species of Phytophthora, plant pathogenic eukaryotic microbes, can cause disease on many tree species. Genome sequencing of species from this genus has helped to determine components of their pathogenicity arsenal. Here we sequenced genomes for two widely distributed species, P. pseudosyringae and P. boehmeriae, yielding genome assemblies of 49 Mb and 40 Mb, respectively. We identified more than 280 candidate disease promoting RXLR effector coding genes for each species, and hundreds of genes encoding candidate plant cell wall degrading carbohydrate active enzymes (CAZymes). These data boost genome sequence representation across the Phytophthora genus, and form resources for further study of Phytophthora pathogenesis.
