Abstract:
... Here we describe the proteome of the fungus Hemileia vastatrix by label free mass spectrometry (LC–MS/MS). H. vastatrix is the causal agent of coffee rust disease, causing great economic losses in this crop. The objective of our work was to identify H. vastatrix proteins potentially involved in host colonization and infection, by exploring the shotgun proteomics approach. A total of 742 proteins w ...

Abstract:
... A rust disease on Potentilla indica was found in Saitama, Japan in 2021. The pathogen was identified as Phragmidium duchesneae (= Ph. mexicanum) based on its morphology and nucleotide sequence of large subunit of the ribosomal RNA gene. This fungus was pathogenic on Po. hebiichigo and Po. indica in inoculation tests, as reported elsewhere in the world. This is the first report of a rust disease on ...

Abstract:
... Pucciniales are fungal pathogens of plants that cause devastating rust diseases in agriculture. Chemically-synthesized pesticides help farmers to control rust epidemics, but governing bodies aim at limiting their use over the next decade. Defense peptides with antimicrobial activities may help to innovate a next generation of phytosanitary products for sustainable crop protection. This review comp ...
... Globalisation has resulted in the spread of infectious plant diseases to new regions and host species and the novel disease caused by myrtle rust poses a global threat to naïve hosts in the Myrtaceae family of plants. This study uses a focal species, Tristaniopsis exiliflora, to explore the climatic and microclimatic preference of the myrtle rust disease (Austropuccinia psidii). Populations of T. ...

Abstract:
... Salicylic acid (SA) and jasmonic acid (JA) often play distinct roles in plant defence against pathogens. Research from Arabidopsis thaliana has established that SA‐ and JA‐mediated defences are more effective against biotrophs and necrotrophs, respectively. These two hormones often interact antagonistically in response to particular attackers, with the induction of one leading to suppression of th ...

Abstract:
... Matromorphs or maternals are non-hybrid diploid offspring which originate entirely from the maternal parent and facilitate in obtaining instant homozygous lines from heterozygous base population thereby, shortening the time requirement of conventional breeding method for the production of homozygous lines. Per se performance of twelve advanced generations of matromorphs (Mat₃) along with their ten ...

Abstract:
... Himalayan balsam (Impatiens glandulifera) is one of the most prolific non-native species in Europe. Since 2014, the highly-specific rust fungus, Puccinia komarovii var. glanduliferae, has been released into Great Britain as a classical biological control agent for this invasive weed. Prior to its release, research focused on ensuring the safety of the pathogen, elucidating its life cycle and verif ...

Extensive survey carried out to assess the severity of cowpea rust disease in four districts of northern Karnataka viz., Dharwad, Belagavi, Bagalkot and Haveri during kharif, rabi and summer seasons of 2014-15 registered maximum mean severity of cowpea rust in Dharwad district (35.29%) followed by Belagavi (34.06%) and Haveri district (31.38%). The minimum severity was noticed in Bagalkot district ...
rustdiseases, etc ; Cronartium; abietic acid; acetone; forests; sesquiterpenoids; wood; Northern European region; Show all 8 Subjects
Abstract:
... Cronartium pini causes economic losses especially on Scots pine in northern Europe. Scots pine reacts to rust infection by resin flow. The chemicals enriched in wood after Cronartium infection have not been investigated before. We investigated resin acids and mono‐ and sesquiterpenes produced in Cronartium‐infected wood. Cronartium‐infected wood was extracted with acetone, and the extractives were ...

Abstract:
... A serious Juniperus rigida rust disease was found in Gansu Province, China. The disease incidence is approximately 80–90%. We also found rust disease on both Cotoneaster multiflorus and Sorbus in the same location. Two novel Gymnosporangium species were identified from the infected plants. Based on morphological observations and phylogenetic analyses, we describe the two new taxa as G. gansuense a ...
... The rust fungi (Pucciniales) are among the most common and devastating pathogens of field crops and forest tree species worldwide. Given the importance of the rusts in agriculture and forestry, this Special Issue of the Canadian Journal of Plant Pathology brings together a variety of papers on rust disease management and biology. The Special Issue comprises 16 full-length articles on rust pathogen ...
... Rust disease is an important problem for leek cultivation worldwide. It reduces market value and in extreme cases destroys the entire harvest. Farmers have to resort to periodical full-field fungicide applications to prevent the spread of disease, once every 1 to 5 weeks, depending on the cultivar and weather conditions. This implies an economic cost for the farmer and an environmental cost for so ...

Abstract:
... Plants play important roles as habitat and food for a tremendous diversity of specialist animals and fungi. The disappearance of any plant species can lead to extinction cascades of its associated biota. In consequence, documenting the diversity and specificity of plant‐associated organisms is of high practical relevance in biodiversity conservation. Here, we present the first large‐scale molecula ...
... Helianthus verticillatus, the whorled sunflower, is an endangered species found only in the southern United States (Trigiano et al. 2021) that is being developed for ornamental uses. This sunflower species requires little to no maintenance, produces spectacular floral displays from September into October, and attracts numerous potential pollinators, including many native bees (Strange et al. 2020) ...

Abstract:
... Groundnut (Arachis hypogaea L.) is a multi-purpose legume serving millions of farmers and their value chain actors globally. Use of old poor-performing cultivars contributes to low yields (< 1 t/ha) of groundnut in sub-Saharan Africa including Tanzania. The objectives of this study were to determine the extent of genetic variation among diverse groundnut collections using phenotypic traits and sim ...
