GsSRK, a G-type lectin S-receptor-like serine/threonine protein kinase, is a positive regulator of plant tolerance to salt stress

Pea lectin receptor-like kinase functions in salinity adaptation without yield penalty, by alleviating osmotic and ionic stresses and upregulating stress-responsive genes

“…), exhibited comparatively higher tolerance to salinity stress than the empty vector control and the tobacco wild type plants used as controls. Similar salinity stress tolerant phenotype has also been reported for Arabidopsis and Glycine soja LecRLKs (Deng et al 2009;Sun et al 2013). Under normal conditions, the constitutive overexpression of PsLecRLK led to a slight yield penalty (statistically, non-significant), as also observed in case of drought stress responsive OsNAC6 overexpression in rice plants (Nakashima et al 2007).…”

“…Salinity stress tolerance phenotype from LecRLKs from plant species such as, Glycine soja (Sun et al 2013), Arabidopsis thaliana (Huang et al 2013;Deng et al 2009;He et al 2004) has been demonstrated. Previous study on PsLecRLK showed that lectin-domain was essential to provide salinity stress tolerance to bacteria as kinase-domain alone could not ensure their survival under salinity stress (Joshi et al 2010).…”

“…On the basis of domain organization and identity, the LecRLK family has been subdivided in L-type, G-type and C-type LecRLKs (Bouwmeester and Govers 2009). Though, many studies have been carried out on evolution and characterization of this gene family (André et al 2005;Barre et al 2002;Bouwmeester and Govers 2009;Gouget et al 2006;Hervé et al 1999) and recently on biotic stress tolerance (Bonaventure 2011;Chen et al 2006;Desclos-Theveniau et al 2012;Gilardoni et al 2011;Kanzaki et al 2008;Singh et al 2012), very few reports are available on the putative role of LecRLKs in abiotic stress tolerance, and specifically on salinity stress tolerance (Deng et al 2009;He et al 2004;Huang et al 2013;Joshi et al 2010;Sun et al 2013). Also, most of these reports lack mechanistic insight to explain the salinity tolerance phenotype.…”

Mitochondrial ascorbate–glutathione cycle and proteomic analysis of carbonylated proteins during tomato (Solanum lycopersicum) fruit ripening

“…A small group of transmembrane protein kinases have been identified in Arabidopsis thaliana mitochondrial proteome and it has been suggested their participation in signaling mechanisms dependent on phosphorylation involved in diverse physiological functions such as growth, development and retrograde (RTG) signaling. Even though the function of these oxidized receptors has not been reported in fruit, their role as cell redox state specific sensors has been already demonstrated (Schwarzländer & Finkemeier, 2013;Sun et al, 2013). Additionally, two proteins related to protein degradation and splicing were identified as target of carbonylation (Table 2).…”

Optimizing de novo transcriptome assembly and extending genomic resources for striped catfish (Pangasianodon hypophthalmus)

“…According to Hanks et al (1988), protein kinases fall into three broad classes, characterized with respect to substrate specificity and include serine/threonineprotein kinases, tyrosine-protein kinases and dual specificity protein kinases. Sun et al (2013) reported that G-type lectin S-receptor-like serine/threonine protein kinase with a highly conserved serine/threonine protein kinase catalytic domain plays a crucial role in plant responses to salt stress. Furthermore, PKR (protein kinase R), a serinethreonine kinase, has roles in the innate immune response in fugu (Del Castillo et al, 2012).…”
