Summary: | ASYMMETRIC LEAVES2/LATERAL ORGAN BOUNDARIES
(
AS2/LOB
) genes are a family of plant specific transcription factors, which play an important role in the regulation of plant lateral organ development and metabolism. However, a genome-wide analysis of the
AS2/LOB
gene family is still not available for barley. In the present study, 24
AS2-like
(
ASL
)/
LOB domain
(
LBD
) genes were identified based on the barley (
Hordeum vulgare
L.) genome sequence. A phylogenetic tree of ASL/LBD proteins from barley,
Arabidopsis
, maize, and rice was constructed. The
ASL/LBD
genes were classified into two classes, class I and class II, which were divided into five and two subgroups, respectively. Genes homologous in barley and
Arabidopsis
were analyzed. In addition, the structure and chromosomal locations of the genes were analyzed. Expression profiles indicated that barley
HvASL/LBD
genes exhibit a variety of expression patterns, suggesting that they are involved in various aspects of physiological and developmental processes. This genome-wide analysis of the barley
AS2/LOB
gene family contributes to our understanding of the functions of the
AS2/LOB
gene family. |
