The cell wall of the biflagellate alga Chlamydomonas reinhardtii is a multilayered, extracellular matrix composed of carbohydrates and 20-25 polypeptides. To learn more about the forces responsible for the integrity of this cellulose-deficient cell wall, we have begun studies to identify and characterize the framework of the wall and to determine the(More)
During fertilization in the biflagellated alga, Chlamydomonas reinhardtii, gametes of opposite mating types adhere to each other via agglutinin molecules located on their flagellar surfaces, generating a sexual signal that induces several cellular responses including cell wall release. This cell contact-generated signal is mediated by cAMP and release of(More)
During the mating reaction in Chlamydomonas reinhardtii mating type plus and mating type minus gametes adhere to each other via adhesion molecules on their flagellar surfaces. This adhesive interaction induces a sexual signal leading to release of a cell wall degrading enzyme, lysin, that causes wall release and degradation. In this article, we describe the(More)
As counselors we often offer compassion to our clients and support them in cultivating it for themselves; however, this aspect of counselor development may be absent in our own self-care practices. How do counselors cultivate self-compassion given the myriad of challenges that arise in their practice? Although there is a wealth of research on counselor(More)
