   1.5.99.12 | evolution |
a total of 8 cytokinin dehydrogenase CKX gene family members are identified from 'Kyoho' grape genome. All CKXs have 3-5 introns. The CKX family members have two highly conserved domains: an oxidase FAD-binding domain and a cytokinin dehydrogenase 1, FAD/cytokinin binding domain |

in 228 barley landraces and 216 wild accessions, 14 haplotypes of gene CKX2 have been identified, five of these with ten or more members, coding for four different protein variants. The amino acid substitution specific to haplotype 3 can result in a change in the functional properties of the CKX2 protein. Haplotypes 1-3 have overlapping geographical distributions in the wild population, but the average rainfall amounts at the collection sites for haplotype 3 plants are significantly higher during November to February compared to the equivalent data for plants of haplotypes 1 and 2 |

| 1.5.99.12 | physiological function |
a CKX2 mutant shows longer panicle with dense branching pattern and higher seed setting rate compared to the wild-type. The grains in the mutant are markedly longer, wider, and heavier compared to the wild-type. A higher number of the spikelet cells with bigger size result in larger grains in the mutant strain. Mutant panicles have a decreased CKX2 expression in and display reduced cytokinin dehydrogenase enzyme activity, leading to remarkably higher endogenous cytokinin content |
