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.
