Phenotypes of cytoskeletal mutants.
Phenotypic studies continue to contribute to an understanding of the functions of cytoskeletal proteins. Many of these studies indicate some degree of functional redundancy within a family of cytoskeletal proteins. Some surprises have emerged, such as suggestions of unexpected relationships between the actin and microtubule cytoskeletons. Finally, phenotypic studies have provided evidence for a...
متن کاملThe multiple phenotypes of allosteric receptor mutants.
Channel-linked neurotransmitter receptors are membrane-bound heterooligomers made up of distinct, although homologous, subunits. They mediate chemo-electrical signal transduction and its regulation via interconversion between multiple conformations that exhibit distinct pharmacological properties and biological activities. The large diversity of functional properties and the widely pleiotropic ...
متن کاملMelanotic mutants in Drosophila: pathways and phenotypes.
Mutations in >30 genes that regulate different pathways and developmental processes are reported to cause a melanotic phenotype in larvae. The observed melanotic masses were generally linked to the hemocyte-mediated immune response. To investigate whether all black masses are associated with the cellular immune response, we characterized melanotic masses from mutants in 14 genes. We found that ...
متن کاملPhenotypes of pleiotropic-negative sporulation mutants of Bacillus subtilis.
The phenotypic properties of representatives of the five genetic classes of pleiotropic-negative sporulation mutants have been investigated. Protease production, alkaline and neutral proteases, was curtailed in spoA mutants, but the remainder of mutant classes produced both proteases, albeit at reduced levels. The spoA and spoB mutants plaqued phi2 and phi15 at high efficiency, but the efficien...
متن کاملNodulation phenotypes of gibberellin and brassinosteroid mutants of pea.
The initiation and development of legume nodules induced by compatible Rhizobium species requires a complex signal exchange involving both plant and bacterial compounds. Phytohormones have been implicated in this process, although in many cases direct evidence is lacking. Here, we characterize the root and nodulation phenotypes of various mutant lines of pea (Pisum sativum) that display alterat...
