Role in Bud Formation
RHO? encodes a Rho-type small GTPase of the yeast Saccharomyces cereuisiae. We isolated temperaturesensitive alleles and a dominant active allele of RH03. Tsrho? cells lost cell polarity during bud formation and grew more isotropically than wild-type cells at nonpermissive temperatures. In contrast, cells carrying a dominant active mutant RHO? displayed cold sensitivity, and the cells became el...
متن کاملDynamics of nonequilibrium membrane bud formation.
The dynamical response of a lipid membrane to a local perturbation of its molecular symmetry is investigated theoretically. A density asymmetry between the two membrane leaflets is predominantly released by in-plane lipid diffusion or membrane curvature, depending upon the spatial extent of the perturbation. It may result in the formation of nonequilibrium structures (buds), for which a dynamic...
متن کاملControl of digit formation by activin signalling.
Major advances in the genetics of vertebrate limb development have been obtained in recent years. However, the nature of the signals which trigger differentiation of the mesoderm to form the limb skeleton remains elusive. Previously, we have obtained evidence for a role of TGFbeta2 in digit formation. Here, we show that activins A and B and/or AB are also signals involved in digit skeletogenesi...
متن کاملAXR1 acts after lateral bud formation to inhibit lateral bud growth in Arabidopsis.
The AXR1 gene of Arabidopsis is required for many auxin responses. The highly branched shoot phenotype of mature axr1 mutant plants has been taken as genetic evidence for a role of auxin in the control of shoot branching. We compared the development of lateral shoots in wild-type Columbia and axr1-12 plants. In the wild type, the pattern of lateral shoot development depends on the developmental...
متن کاملEvaluation on Some Treatments After Spring Frost Damage in Inflorescence Bud Formation in Pistachio Orchard
(In the 3rd of April 2008) and in the morning of (16 April 2008), the temperature reached - 6 ο C in some pistachio gardens of Kerman County especially in Sirjan. The coldness was so high that affected not only on the open flowers but also on bud endings and lop growth, So that the next year product was endangered, as well. In order to study the effect of some treatments and decrease the damage...
