objective: the lrr (leucine rich proteoglycans) is a molecular recognition motif found in proteins with some roles in cell adhesion, signal transduction, dna repair and rna processing. opticin is a member of this family. takanosu et al (2001) detected messenger rna expression of mouse opticin in the eye, heart, brain, testis, thyroid and epididymis by dot blot hybridization. in this study, exp...
background: as for human trichomoniasis the host-parasite relationship is very complex, and the broad ranges of clinical symptoms are unlikely be attributable to a single pathogenic mechanism. specific random amplified polymorphic dna (rapd) markers of 490 bp, 720 bp and 460 bp using the primers tv-5, opa-6 and opa-11, respectively, were reported. this was the first description of possible gen...
A large number of immune receptors consist of nucleotide binding site-leucine rich repeat (NBS-LRR) proteins and leucine rich repeat-receptor-like kinases (LRR-RLK) that play a crucial role in plant disease resistance. Although many NBS-LRR genes have been previously identified in Zea mays, there are no reports on identifying NBS-LRR genes encoded in the N-terminal Toll/interleukin-1 receptor (...
Nucleotide-binding leucine-rich repeat sequence (NBS-LRR) protein is the main immune receptor in plants and participates plant resistance to pathogens. When NBS-LRR activated by pathogen’s effector protein, its conformation changes from an inhibitory state state, then it activates downstream signal transduction initiates defense responses inhibit growth of The has major three domains: NBS, LRR ...
Genome-wide characterisation, evolution and expression analysis of the leucine-rich repeat receptor-like kinase (LRR-RLK) gene family in cucumbers | Jia Yu, Bo Zhang, Sisi Liu, Wei Guo, Yifan Gao, Hongyan Sun Agricultural Journals
We present a novel approach to design repeat proteins of the leucine-rich repeat (LRR) family for the generation of libraries of intracellular binding molecules. From an analysis of naturally occurring LRR proteins, we derived the concept to assemble repeat proteins with randomized surface positions from libraries of consensus repeat modules. As a guiding principle, we used the mammalian ribonu...
In plants, many of the innate immune receptors or disease resistance (R) proteins contain a NB-LRR (Nucleotide-binding site, Leucine-rich repeat) structure. The recent findings regarding NB-LRR signaling are summarized in this article. An emerging theme is that two NB-LRRs can function together to mediate disease resistance against pathogen isolates. Also, recent results delineate the NB-LRR pr...
Plants must adapt to their environment and require mechanisms for sensing their surroundings and responding appropriately. An expanded family of more than 200 leucine-rich repeat (LRR) receptor kinases (LRR-RKs) transduces fluctuating and often contradictory signals from the environment into changes in nuclear gene expression. Two LRR-RKs, BRASSINOSTEROID INSENSITIVE 1 (BRI1), a steroid recepto...
The nucleotide-binding site (NBS)-leucine-rich repeat (LRR) gene family is crucially important for offering resistance to pathogens. To explore evolutionary conservation and variability of NBS-LRR genes across grass species, we identified 88, 107, 24, and 44 full-length NBS-LRR genes in sorghum, rice, maize, and Brachypodium, respectively. A comprehensive analysis was performed on classificatio...
