A new antifungal diketopiperazine named haematocin was isolated from the culture broth of Nectria haematococca Berk. et Br. (880701a-1) causing blight disease on ornamental plants, Phalaenopsis spp. and Doritanopsis spp. Its structure was established by spectroscopic methods. Haematocin inhibited the germ-tube elongation and spore-germination of Pyricularia oryzae at the ED50 values of 30 micro...
Germ-tube emergence in Aspergillus nidulans exhibits partial synchrony. Germ tubes were first detected at 210 min. after inoculation of spores into a liquid medium. Almost all spores produced germ tubes within 360 min., 4 9 3 % of them doing so between 240 and 300 min. Increase in dry weight was first detected at 120 min. and various constituents at the following times: RNA (30 min.), Kjeldahl ...
The nematode Caenorhabditis elegans has been established as a modeling organism in biomedical research for several decades. Its hermaphrodite germ line encompasses key developmental concepts like stem cell differentiation and apoptosis; therefore it provides a good model system for these basic concepts. Here, we have extended and refined our previous computational model, which encompasses devel...
Feathers are complex assemblages of multiple morphological innovations. Recent research on the development and evolution of feathers has produced new insights into the origin and diversification of the morphological innovations in feathers. In this article, I review and discuss the contribution of three different factors to the evolution of morphological innovations in feathers: feather tubular...
