|
Registration of new gene symbols
|
The following genes are newly registered:
GENE SYMBOL REGISTRATION No. 138
|
Registrant:
|
Katsuyuki Ichitani, Yutaka Okumoto and Takatoshi Tanishaka
|
(Graduate School Agricultural Kyoto University, Kyoto, Japan)
|
Gene name:
|
Photosensitivity 9
|
|
Character expression:
|
Dominant gene for photoperiod sensitivity. Its recessive
allele
|
se9 inhibits the expression of photopenod sensitivity genes
at
other loci. The segregation of this locus can be observed
only
under extremely long daylenghts, presumably more than 17th.
|
Name of original line:
|
Se9, Eiko
|
se9, Wase-fukoku, Nori 20 and Kirara 397
|
Remark:
|
Data on F2 segregation and photoperiodic responses of origi
|
nal lines are reported.
