Two distinct distributions of F-actin are present in the hyphal apex of the oomycete Achlya bisexualis.
We show that two distinct distributions of F-actin are present in the hyphal apex of the oomycete Achlya bisexualis, that have been chemically fixed with a combination of methylglyoxal and formaldehyde and stained with Alexa phalloidin. In approximately one half of the hyphae examined, an F-actin depleted zone within the apical F-actin cap was observed. The remaining hyphae had a continuous api...
متن کاملSexual Hormones in Achlya
The sexual reproductive process of Achlya ambisexualis, a heterothallic form belonging to a well known and widely distributed genus of saprophytic aquatic fungi, is initiated and coordinated by means of specific substances (Raper, 1939, a). Four of these substances have been demonstrated (Raper, 1939, b, 1940) in the r&es of initiators and coordinators of the various stages in the sexual proces...
متن کاملIonophores in Dairy Rations
Introduction Ionophores have been used extensively in the beef industry in Canada since 1977. Until recently, there has been no label indication for use of ionophores in lactating dairy cattle. Ionophores are feed additives that alter rumen microbial populations through ion transfer across cell membranes. In Canada, the label warning prohibiting the use of Rumensin premix in lactating dairy ca...
متن کاملSelf - Assembling Ionophores
interpreted by using a variety of schemes involving Ni(III)/Ni( I and Ni( I I I ) /Ni( I I ) /Ni( I ) / Ni(0)22 formal oxidation states. In all these schemes, the assignment of Ni(l1l) to the oxidized forms of the enzymes is based on the observation of hyperfine in 61Ni-labeled enzymes, the similarity of the EPR spectra to EPR spectra of tetragonal Ni(II1) coordination compounds, and the associ...
متن کاملProduction of hormone B by Achlya heterosexualis.
Sexual morphogenesis in Achlya, a filamentous water mold, is initiated by two hormones. Hormone A, or antheridiol, is a C-29 steroid. Four stereoisomers of antheridiol have been synthesized. The natural one (antheridiol 22S 23R) and its 7-deoxy 7-dihydro form, when added to an aerated culture of hermaphroditic Achlya heterosexualis, stimulated this mold to secrete twice as much hormone B as the...
