Reduced plant height and culm robustness are quantitative
characteristics important for assuring cereal crop yield and
quality under adverse weather conditions. A very limited
number of short-culm mutant alleles were introduced into
commercial crop cultivars during the Green Revolution
although more than 1000 different short-culm barley
mutants have been isolated and classified in different
phenotypic groups according to culm length and additional
pleiotropic characters. We are currently employing
available short-culm barley mutants in order to identify the
genes responsible for regulation of culm length. In the
present project we focus on the barley genes ert-c and ert-k,
which are key genes for regulation of plant architecture.
We have performed exome capture analyses of 24 mutants
and will now analyze these NGS sequences in order to
identify the ert-c and ert-k genes.
