| identification of a protein from rust fungi transferred from haustoria into infected plant cells. | the formation of haustoria is one of the hallmarks of the interaction of obligate biotrophic fungi with their host plants. in addition to their role in nutrient uptake, it is hypothesized that haustoria are actively involved in establishing and maintaining the biotrophic relationship. we have identified a 24.3-kda protein that exhibited a very unusual allocation. rust transferred protein 1 from uromyces fabae (uf-rtp1p) was not only detected in the host parasite interface, the extrahaustorial ma ... | 2005 | 16353548 |
| different resistance mechanisms of medicago truncatula ecotypes against the rust fungus uromyces striatus. | abstract a pathosystem consisting of the model plant medicago truncatula and the rust fungus uromyces striatus was characterized. from a collection of 113 mostly european accessions of m. truncatula, the vast majority were found to be susceptible to u. striatus, whereas 5 accessions showed strong resistance reactions. stomatal surface characteristics, even if partly occluded, did not interfere with the ability of u. striatus germ tubes to infect. after penetration, the resistant ecotypes reacted ... | 2005 | 18943984 |
| effects of leaf wetness duration and temperature on infection efficiency, latent period, and rate of pustule appearance of rust in alfalfa. | abstract dew and growth chamber tests were conducted on the alfalfa cultivar ranger to determine the effect of duration of leaf wetness and temperature on several components of the alfalfa rust (uromyces striatus) monocycle. duration of leaf wetness and temperature both had significant effects on pustule development. infection efficiency (number of alfalfa rust pustules per leaf) increased linearly as duration of leaf wetness was increased from 4 to 24 h after inoculation. there was an inverse l ... | 1997 | 18945066 |
| transcription factor profiling leading to the identification of putative transcription factors involved in the medicago truncatula-uromyces striatus interaction. | understanding the host response to uromyces sp., the causal agent of rust in many crop species, is crucial in elucidating the specific biology of rust resistance. in an attempt to unravel the medicago truncatula-u. striatus interaction, we performed a global analysis of transcription factor (tf) expression in resistant and susceptible accessions of the model plant m. truncatula during infection with u. striatus. for this purpose, an established qpcr platform was applied, consisting of specific p ... | 2010 | 20582581 |
