The NB-LRR proteins RGA4 and RGA5 interact functionally and physically to confer disease resistance.
Plant resistance proteins of the class of nucleotide-binding and leucine-rich repeat domain proteins (NB-LRRs) are immune sensors which recognize pathogen-derived molecules termed avirulence (AVR) proteins. We show that RGA4 and RGA5, two NB-LRRs from rice, interact functionally and physically to mediate resistance to the fungal pathogen Magnaporthe oryzae and accomplish different functions in ...
متن کاملThe Rho GTPase-activating proteins RGA-3 and RGA-4 are required to set the initial size of PAR domains in Caenorhabditis elegans one-cell embryos.
Caenorhabditis elegans embryos establish cortical domains of PAR proteins of reproducible size before asymmetric cell division. The ways in which the size of these domains is set remain unknown. Here we identify the GTPase-activating proteins (GAPs) RGA-3 and RGA-4, which regulate the activity of the small GTPase RHO-1. rga-3/4(RNAi) embryos have a hypercontractile cortex, and the initial relat...
متن کاملFunctions of the novel RhoGAP proteins RGA-3 and RGA-4 in the germ line and in the early embryo of C. elegans.
We have identified two redundant GTPase activating proteins (GAPs) - RGA-3 and RGA-4 - that regulate Rho GTPase function at the plasma membrane in early Caenorhabditis elegans embryos. Knockdown of both RhoGAPs resulted in extensive membrane ruffling, furrowing and pronounced pseudo-cleavages. In addition, the non-muscle myosin NMY-2 and RHO-1 accumulated on the cortex at sites of ruffling. RGA...
متن کاملVacuum Diagnosis with an RGA
Stanford Research Systems phone: (408)744-9040 www.thinkSRS.com Residual Gas Analyzer (RGA) is the term used for a class of quadrupole mass spectrometers that typically cover mass ranges from 1 to 100 or 200 amu (atomic mass units), and are intended to be used for the analysis of the gasses present in high and ultra-high vacuum. The RGA’s resolution is sufficient to clearly distinguish peaks th...
متن کاملMutations in an Atypical TIR-NB-LRR-LIM Resistance Protein Confer Autoimmunity
In order to defend against microbial infection, plants employ a complex immune system that relies partly on resistance (R) proteins that initiate intricate signaling cascades upon pathogen detection. The resistance signaling network utilized by plants is only partially characterized. A genetic screen conducted to identify novel defense regulators involved in this network resulted in the isolati...
