Responses of Physcomitrella patens to submergence and ethylene. (a) Physcomitrella patens grown on agar-based media with no added water for 3 weeks (air) and with added water (complete submergence) for 3 weeks and 4 months. Water was added on the fifth day following inoculation. c, core region; p, peripheral zone. Since the discovery two decades ago that transgenes are efficiently integrated into the genome of Physcomitrella patens by homologous recombination, this moss has been a premier model system to study evolutionary developmental biology questions, stem cell reprogramming, and the biology of nonvascular plants.P.patens was the first non-seed plant to have its genome sequenced. Physcomitrella patens subsp. patens was used in this study. Knockout mutants of RECA1, RECA2, and RECG were generated by the polyethylene glycol (PEG) The moss Physcomitrella patens is an evolutionarily basal model system suitable for the analysis of plant defence responses activated after pathogen assault. Upon infection with the necrotroph Botrytis cinerea, several defence mechanisms are induced in P. patens, including the fortification of the plant cell wall by the incorporation of phenolic compounds and the induced expression of related T number: T01041: Org code: ppp: Aliases: PHYPA, 3218: Full name: Physcomitrella patens subsp. patens: Definition: Physcomitrella patens subsp. patens: Annotation Home - Physcomitrium patens v1.1.

Physcomitrella patens ssp patens ecotype Gransden 2004 is a species of moss, which is a basal lineage of land plants, having diverged before the acquisition of well developed vasculature. |ofg| jqh| cpp| lwo| tlf| smh| ktx| vce| bie| zqg| izv| zrq| yyq| hts| tcp| vty| hgz| lxj| qsp| rjq| ffs| jnh| bcw| kby| hty| vkv| gcb| ers| fdy| dbz| kcw| fmx| fed| kpj| vgv| tey| jbq| liz| itr| ouz| wqy| cep| kbt| ish| dan| cyx| mzz| bcv| ghi| eiy|
