A leaf spot of figwort ( Scrophularia ningpoensis ) caused by Phoma sp
A leaf spot of figwort (Scrophularia ningpoensis) caused by Phoma sp. Abstract: Since 2006, a new disease caused by Phoma sp. has been identified on figwort (Scrophularia ningpoensis) in Hubei province, China. The pathogen was isolated from diseased S. ningpoensis leaves growing under field conditions, and attempts were made to identify it by cultural and morphological characteristics as well a...
متن کاملThe population genomic basis of geographic differentiation in North American common ragweed (Ambrosia artemisiifolia L.)
Common ragweed (Ambrosia artemisiifolia L.) is an invasive, wind-pollinated plant nearly ubiquitous in disturbed sites in its eastern North American native range and present across growing portions of Europe, Africa, Asia, and Australia. Phenotypic divergence between European and native-range populations has been described as rapid evolution. However, a recent study demonstrated major human-med...
متن کاملIllumina sequencing of the chloroplast genome of common ragweed (Ambrosia artemisiifolia L.)
Common ragweed (Ambrosia artemisiifolia L.) is the most widespread weed and the most dangerous pollen allergenic plant in large areas of the temperate zone. Since herbicides like PSI and PSII inhibitors have their target genes in the chloroplast genome, understanding the chloroplast genome may indirectly support the exploration of herbicide resistance and development of novel control methods. T...
متن کاملIllumina Sequencing of Common (Short) Ragweed (Ambrosia artemisiifolia L.) Reproductive Organs and Leaves
Ambrosia artemisiifolia L. (A. artemisiifolia, common ragweed) is one of themost aggressive, rapidly spreading and highly allergenic weeds found in many agricultural settings in the temperate zone. Chemical control of ragweed has some limitation in some crops, therefore it may cause reduced yields both in Europe and North America. The most affected are maize, sunflower, soya bean and pea in Eur...
متن کاملGenetic differentiation in life-history traits of introduced and native common ragweed (Ambrosia artemisiifolia) populations.
Introduced species represent opportunities to observe evolution over contemporary time scales, and as exotics encounter new environments, adaptive responses can occur, potentially contributing to invasion. Here, we compare 22 native North American populations and 12 introduced European populations of common ragweed (Ambrosia artemisiifolia) in five common gardens (control, herbivory, light stre...
