ABSTRACT: In leucine-rich repeat (LRR) receptor-like kinase XI
subfamily, Arabidopsis HAESA (AtHAE) and two closely related HAESA-LIKE
(AtHSL1 and AtHSL2) constitute a small branch. Several reports have
described the function and the involved signaling pathway that AtHAE and AtHSLs
are involved in. However, the family members and functions of HAE and HSL in
rice have not been reported. Here, we performed a genome-wide analysis of the
HAE/HSL kinase family in rice. A total of 17 OsHSLs were identified in the
genome. Of these, only Os11g11890
was annotated as HSL2; all the other members were annotated as HSL1.
Phylogenetic analysis revealed that OsHSLs diverged into three groups, with
three Arabidopsis members
constituting a subgroup of group I. Domain analysis revealed that all the
homologues had 9-19 LRR repeats and a typical kinase domain at the C-terminus,
except that four members lost or evolved their kinase domains. Expression
analysis revealed that OsHSLs were co-expressed with genes involved in biotic
and abiotic stresses. Microarray data revealed that most OsHSLs were highly
expressed in the vegetative tissues and only two members were highly expressed
in the reproductive tissues. Most OsHSLs changed their expression profiles when
subjected to drought, and salt stress treatments. Our results provide an
overview of OsHSL gene family in rice, and suggest that OsHSLs possibly
function under biotic and abiotic stresses, thus would help for elucidating the
function of OsHSLs gene family in vivo.
