Cell wall permeability and its relationship to spore release in Achlya intricata

New information on the mechanism of forcible ascospore discharge from Ascobolus immersus

“…After all, our mathematical analysis shows that fairly modest turgor is sufficient to launch the spores. Similar conclusions about the utility of seemingly low hydrostatic pressures have been reached from prior research on sporangial emptying and conidial germination (Money and Howard, 1996;Money and Webster, 1988).…”

Evolution of Spore Release Mechanisms in the Saprolegniaceae (Oomycetes): Evidence from a Phylogenetic Analysis of Internal Transcribed Spacer Sequences

“…36051), Thraustotheca clavata (de Bary) Humphrey (34112), and Dictyuchus sterile Coker (44891). Achlya intricata Beneke, originally obtained from the culture collection at the University of Reading, United Kingdom, courtesy of Dr. Michael Dick, is now deposited at the ATCC (66594); this species was selected for the investigation because spore release has been studied more intensively in this species than in any other member of the Saprolegniaceae (Money and Webster, 1988, and references therein). Mycelia were grown in 100-ml batches of liquid PYG medium (0.1% peptone, 0.1% yeast extract, 0.3% glucose), inoculated with 10-mm-diameter plugs from PYG agar cultures, and incubated at 24°C for 2-7 days on an orbital shaker.…”

Invasive Hyphal Growth in Wangiella dermatitidis Is Induced by Stab Inoculation and Shows Dependence upon Melanin Biosynthesis

“…Single-classification ANOVA indicated significant differences between treatments and controls at P Ͻ 0.005** and P Ͻ 0.001***. nm), and the walls of oomycete sporangia are even more permeable (Money and Webster, 1988).…”
