TLDR
A picture is emerging where CrRLKs are part of a conserved signal transduction cascade important for growth maintenance in different cell types, with emphasis on the newly identified signalTransduction pathways activated downstream of Cr RLKs.Abstract:
Receptor-like kinases (RLKs) are a family of transmembrane proteins with a variable ligand-binding extracellular domain and a cytoplasmic kinase domain. In Arabidopsis, there are ~600 RLKs believed to have diverse functions during plant growth, development and interactions with the environment. Based on the variable extracellular domain, RLKs can be classified into different subfamilies. The CrRLK subfamily contains 17 members in Arabidopsis and characterization of some of its members suggests a role for these proteins in the regulation of growth and reproduction. The present review focuses on the roles of CrRLKs in the regulation of polarized growth with emphasis on the newly identified signal transduction pathways activated downstream of CrRLKs. A picture is emerging where CrRLKs are part of a conserved signal transduction cascade important for growth maintenance in different cell types.read more

Reactive oxygen species mediate pollen tube rupture to release sperm for fertilization in Arabidopsis
Qiaohong Duan,Daniel Kita,Daniel Kita,Eric A. Johnson,Mini Aggarwal,Laura Gates,Laura Gates,Hen-Ming Wu,Alice Y. Cheung +8 more
TL;DR: It is shown that FER controls the production of high levels of reactive oxygen species at the entrance to the female gametophyte to induce pollen tube rupture and sperm release, providing evidence for a RHO GTPase-based signalling mechanism to mediate sperm release for fertilization in plants.

FERONIA receptor kinase pathway suppresses abscisic acid signaling in Arabidopsis by activating ABI2 phosphatase
Feng Yu,Lichao Qian,Candida Nibau,Qiaohong Duan,Daniel Kita,Kathryn Levasseur,Xiaoqian Li,Changqing Lu,Hui Li,Congcong Hou,Legong Li,Bob B. Buchanan,Liangbi Chen,Alice Y. Cheung,Dongping Li,Sheng Luan,Sheng Luan +16 more
TL;DR: A cross-talk mechanism is reported that enables a receptor-like kinase, FERONIA (FER), a positive regulator of auxin-promoted growth, to suppress the abscisic acid (ABA) response through activation of ABI2, a negative regulator of ABA signaling.

FERONIA interacts with ABI2-type phosphatases to facilitate signaling cross-talk between abscisic acid and RALF peptide in Arabidopsis.

TL;DR: ABI2 can directly interact and dephosphorylate FER, providing a feedback mechanism for ABA activation of FER and for cross-talk between ABA and peptide hormone RALF in the control of plant growth and responses to stress signals.

GsSRK, a G-type lectin S-receptor-like serine/threonine protein kinase, is a positive regulator of plant tolerance to salt stress.
Xiaoli Sun,Qingyue Yu,Lili Tang,Wei Ji,Xi Bai,Hua Cai,Xiao-Fei Liu,Xiaodong Ding,Xiaodong Ding,Yanming Zhu +9 more
TL;DR: Compared to the wild type Arabidopsis, GsSRK overexpressors exhibited enhanced salt tolerance and higher yields under salt stress, with higher chlorophyll content, lower ion leakage, higher plant height, and more siliques at the adult developmental stage.

THESEUS 1, FERONIA and relatives: a family of cell wall-sensing receptor kinases?
Alice Y Cheung,Hen-Ming Wu +1 more
TL;DR: These findings position the THESEUS 1/FERONIA family RLKs as surface regulators and potential cell wall sensors capable of broadly and profoundly impacting cellular pathways in response to diverse signals.

The Barley Mlo Gene: A Novel Control Element of Plant Pathogen Resistance

TL;DR: Analysis of mutagen-induced recessive alleles of the barley Mlo locus revealed mutations leading in each case to alterations of the deduced Mlo wild-type amino acid sequence, compatible with a dual negative control function of the Mlo protein in leaf cell death and in the onset of pathogen defense.

A domain swap approach reveals a role of the plant wall-associated kinase 1 (WAK1) as a receptor of oligogalacturonides
TL;DR: A chimeric receptor approach is adopted to elucidate the role of Arabidopsis WAK1 and shows that transgenic plants overexpressing Wak1 are more resistant to Botrytis cinerea and are effective against fungal and bacterial pathogens.

The FERONIA Receptor-like Kinase Mediates Male-Female Interactions During Pollen Tube Reception
Juan M. Escobar-Restrepo,Norbert Huck,Sharon A Kessler,Valeria Gagliardini,Jacqueline Gheyselinck,Wei-Cai Yang,Ueli Grossniklaus +6 more
TL;DR: The findings show that the female control of pollen tube reception is based on a FER-dependent signaling pathway, which may play a role in reproductive isolation barriers, and the FER protein accumulates asymmetrically in the synergid membrane at the filiform apparatus.
