evidence for the importance of enzymatic digestion of epidermal walls during subepidermal sporulation and pustule opening in white blister rusts (albuginaceae). | albugo candida, a. ipomoeae-panduratae, pustula tragopogonis, wilsoniana bliti and w. portulacae are widespread obligate biotrophic plant pathogens causing white blister diseases on a variety of flowering plants. their subepidermal mode of sporulation is unique amongst oomycetes and leads to blister-like structures on their hosts similar to those produced by true rusts (uredinales). unlike in true rusts, sporangia are colourless and produced in chains; the first formed, primary sporangium, diffe ... | 2009 | 19484808 |
