Rust is a major Eucalyptus spp. disease, which is especially damaging for early-stage plants. The aim of this study was to verify the pre-infection process of Austropuccinia psidii (A. psidii) in the leaves of three phenological stages of Eucalyptus clones with different resistance levels. Plants from the hybrids of Eucalyptus urophylla × Eucalyptus grandis (E. grandis) with variable levels of ...
A cDNA library constructed from haustoria of the rust fungus Uromyces fabae was screened for clones that are differentially expressed in haustoria. One family of cDNAs (in planta-induced gene 2 [PIG2] was isolated and found to encode a protein with high homologies to fungal amino acid transporters. A cDNA clone containing the complete coding region of PIG2 and the corresponding genomic clone we...
M any destructive crop diseases are caused by filamentous microbes from the kingdoms Fungi (e.g., ascomycetes and basidomycetes) and Stramenopila (oomycetes). Many of these pathogens exploit plants by extracting nutrients from living plant cells (biotrophy) (1). In some cases, biotrophic pathogens have evolved to a state of absolute dependency on their hosts. These obligate biotrophs have lost ...
Abstract Wheat rusts, including stripe, leaf, and stem are severe wheat diseases cause huge yield loss in China annually. Benefiting from utilizing the genetic resistance varieties, rust has been effectively controlled since 1970s; however, stripe leaf rusts still threating production due to lack of effective agricultural regulations. This review summarizes research advances on physiology, epid...
The disease detection by means of hyperspectral reflectance is influenced by the spectral differences between frontside (adaxial surface) and backside (abaxial surface) of a leaf inevitably. Taking yellow rust as an example, this study investigated the spectral differences between frontside and backside of healthy and diseased wheat leaves at grain filling stage using large size samples. We att...
Rust fungi are some of the most devastating pathogens of crop plants. They are obligate biotrophs, which extract nutrients only from living plant tissues and cannot grow apart from their hosts. Their lifestyle has slowed the dissection of molecular mechanisms underlying host invasion and avoidance or suppression of plant innate immunity. We sequenced the 101-Mb genome of Melampsora larici-popul...
Quackgrass, Elymus repens (L.) Gould, is a perennial grass spreading by vigorous underground rhizomes. Because of its capacity for rapid spread and persistence, it is considered as a common weed in many settings worldwide. The cereal rust mite, Abacarus hystrix (Nalepa), is a polyphagous, phytophagous mite attacking quackgrass and many other grasses including wheat. Its feeding causes leaf disc...
Improving resistance to barley leaf rust (caused by Puccinia hordei) is an important breeding objective in most growing regions worldwide. The development and subsequent utilization of high-throughput PCR-based codominant molecular markers remains effective approach select genotypes with multiple genes, permitting efficient gene deployment stewardship. genes Rph20 Rph24 confer widely adult plan...
Barley ( Hordeum vulgare ) is an important crop in Turkey. In this study, 37 barley fields Batman central district and Beşiri (Batman), Gercüş Hasankeyf Kozluk Sason Kocaköy (Diyarbakır), Kurtalan (Siirt), Midyat (Mardin) districts were examined for the presence of leaf diseases. addition, 24 naturally grown wild H. spontaneum populations Beşiri, Hasankeyf, inspected fields, scald caused by Rhy...
