RT Journal Article SR Electronic(1) A1 Patton, A. Marie A1 Marchant, R.YR 1975 T1 The Effect of Cytochalasin B on Hyphal Morphogenesis in Polyporus biennis JF Microbiology, VO 86 IS 2 SP 301 OP 310 DO https://doi.org/10.1099/00221287-86-2-301 PB Microbiology Society, SN 1465-2080, AB SUMMARY: Cytochalasin B inhibited the radial growth rate of Polyporus biennis, and caused an increase in hyphal density through a reduction in the distance between successive branches. Cytochalasin B also produced irregular hyphal profiles and, in a small percentage of hyphae, forked apices. The position of clamp connexions was little affected by cytochalasin B, but the developmental process was specifically inhibited during initiation and during the last two stages, when contact and dissolution of the clamp were occurring. There were no major disruptions of the ultrastructure of the dolipore/parenthesome septum caused by cytochalasin B treatment., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-86-2-301
