Gene : ER A. thaliana

Gene ID  ? AT2G26330
Brief Description  Leucine-rich receptor-like protein kinase family protein  Source: Araport11 (06/2016).
Is Obsolete?  false
Computational Description  ? ERECTA (ER); CONTAINS InterPro DOMAIN/s: Protein kinase, ATP binding site (InterPro:IPR017441), Protein kinase, catalytic domain (InterPro:IPR000719), Leucine-rich repeat-containing N-terminal domain, type 2 (InterPro:IPR013210), Leucine-rich repeat (InterPro:IPR001611), Serine/threonine-protein kinase-like domain (InterPro:IPR017442), Protein kinase-like domain (InterPro:IPR011009), Serine/threonine-protein kinase, active site (InterPro:IPR008271); BEST Arabidopsis thaliana protein match is: ERECTA-like 2 (TAIR:AT5G07180.1).  Source: TAIR, Jun 30, 2015.
Curator Summary  ? Homologous to receptor protein kinases. Involved in specification of organs originating from the shoot apical meristem. Contains a cytoplasmic protein kinase catalytic domain, a transmembrane region, and an extracellular leucine-rich repeat. ER has been identified as a quantitative trait locus for transpiration efficiency by influencing epidermal and mesophyll development, stomatal density and porosity of leaves. It has been implicated in resistance to the bacterium Ralstonia solanacearum and to the necrotrophic fungus Plectosphaerella cucumerina. Together with ERL1 and ERL2, ER governs the initial decision of protodermal cells to either divide proliferatively to produce pavement cells or divide asymmetrically to generate stomatal complexes.  Source: TAIR, Jun 30, 2015.

Three ERECTA-family leucine-rich repeat-receptor-like kinases (ER, ERL1,ERL2) together control stomatal patterning, with specific family members regulating specification of stomatal stem cell fate & differentiation of guard cells. [ER] 16002616

Both genetic and cellular analyses indicate that auxin and the ER pathway regulate cell division and cell expansion in a largely independent but overlapping manner during elaboration of inflorescence architecture. 16126863
ERL2 is haploinsufficient for maintaining female fertility in the absence of ER and ERL1. 17652352
Study reviewed ERECTA functions and indicated ERECTA as a pleiotropic regulator of developmental and physiological processes, as well as a modulator of responses to environmental stimuli. 19303350
Data show that the allele present at ERECTA significantly alters G-matrix structure-in particular the genetic correlations between branch number and flowering time traits-and may also modulate the strength of natural selection on these traits. 19416942
ER has a role in regulating cell wall-mediated disease resistance. 19589071
Analysis of mutants in various backgrounds and complementation analysis of naturally occurring mutant accessions provided evidence that the leucin-rich repeat receptor-like Ser/Thr kinase gene, ERECTA, controls ethylene-induced hyponastic growth. 19796369

The ER family regulates stem cell homeostasis via buffering its cytokinin responsiveness in the Shoot apical meristem (SAM). 22885615
Data demonstrate that during the first two stages of pedicel development ERECTA is important for the rate of cell growth along the proximodistal axis and for cell cycle duration in epidermis and cortex 23050000
Expression of Arabidopsis AtDeltaKinase under its own promoter resulted in transgenic tomato plants with diminished growth, a reduced number of leaves, changed flowering time, and slightly increased stomata density. 23096000

Results suggest that the YDA-MKK4/MKK5-MPK3/MPK6 cascade functions downstream of the ER receptor in regulating localized cell proliferation, which further shapes the morphology of plant organs. 23263767
Data indicate that allelic variation at the ERECTA locus regulates petal shape. 23418598
ERECTA is involved in canalization processes buffering the genetic variation of the shade-avoidance syndrome against environmental light fluctuations. 23444123

ER-family signalling is crucial for ensuring proper expression domains of floral meristem and floral organ identity determinants, and further implies the existence of a non-canonical downstream pathway. 24006425
