TLDR
The cloned ER gene encodes a putative receptor protein kinases, and the results suggest that cell-cell communication mediated by a receptor kinase has an important role in plant morphogenesis.Abstract:
Arabidopsis Landsberg erecta is one of the most popular ecotypes and is used widely for both molecular and genetic studies. It harbors the erecta (er) mutation, which confers a compact inflorescence, blunt fruits, and short petioles. We have identified five er mutant alleles from ecotypes Columbia and Wassilewskija. Phenotypic characterization of the mutant alleles suggests a role for the ER gene in regulating the shape of organs originating from the shoot apical meristem. We cloned the ER gene, and here, we report that it encodes a putative receptor protein kinases. The deduced ER protein contains a cytoplasmic protein kinase catalytic domain, a transmembrane region, and an extracellular domain consisting of leucine-rich repeats, which are thought to interact with other macromolecules. Our results suggest that cell-cell communication mediated by a receptor kinase has an important role in plant morphogenesis.read more

FLS2: an LRR receptor-like kinase involved in the perception of the bacterial elicitor flagellin in Arabidopsis.
TL;DR: The identification of a new locus, FLS2, is described, which is ubiquitously expressed and encodes a putative receptor kinase and shares structural and functional homologies with known plant resistance genes and with components involved in the innate immune system of mammals and insects.

The CLAVATA1 gene encodes a putative receptor kinase that controls shoot and floral meristem size in Arabidopsis
TL;DR: It is provided evidence that CLV1 expression in the inflorescence is specifically associated with meristematic activity, suggesting a role in signal transduction.

Plant Disease Resistance Genes
TL;DR: Isolation of R genes has revealed four main classes of R gene sequences whose products appear to activate a similar range of defense mechanisms, and provides insight into R gene function and evolution, and should lead to novel strategies for disease control.

TL;DR: It is found that rice (Oryza sativa) has nearly twice as many RLK/Pelle members as Arabidopsis does, and it is not simply a consequence of a larger predicted gene number in rice.

Patterns of Amino Acids near Signal‐Sequence Cleavage Sites
TL;DR: In this paper, some such patterns, based on a sample of 78 eukaryotic signal sequences, are presented and discussed, and a first attempt at formulating rules for the prediction of cleavage sites is made.

The leucine-rich repeat: a versatile binding motif.

TL;DR: The crystal structure of ribonuclease inhibitor protein has revealed that leucine-rich repeats correspond to beta-alpha structural units, which are arranged so that they form a parallel beta-sheet with one surface exposed to solvent, so that the protein acquires an unusual, nonglobular shape.

TL;DR: The catalytic domain database (PKINASES) as mentioned in this paper is a large-scale database of protein kinase amino acid sequences, which is used for the initial classification of novel protein kinases and for other studies that require extensive sequence comparisons.

The toll gene of drosophila, required for dorsal-ventral embryonic polarity, appears to encode a transmembrane protein
TL;DR: The Toll gene of Drosophila, a maternal effect gene that plays a central role in the establishment of the embryonic dorsal-ventral pattern, has been cloned using P element tagging and the sequence of cDNAs suggests that the Toll protein is an integral membrane protein with a cytoplasmic domain and a large extracytoplasmaic domain.

TL;DR: The predicted protein shows homology to the receptor domain of several receptor-like protein kinases in Arabidopsis, to antifungal polygalacturonase-inhibiting proteins in plants, and to other members of the leucine-rich repeat family of proteins.
