I.      Registration of new gene symbols

 

The following genes are newly registered:

GENE SYMBOL REGISTRATION No. 160

   Registrant:      T. Kawakatsu1, J.-I. Itoh1, K. Miyoshi1, N. Kurata2, and Y. Nagato1,
 1) Graduate School of Agricultural and Life Sciences, University of Tokyo, Tokyo 113-8657, Japan
 2) National Institute of Genetics, Mishima 411-8540, Japan
   Gene symbol:      pla2
   Gene name:      plastochron 2
   Character expression:      Recessive alleles, pla2-1 and pla2-2, exhibit short plastochron and conversion of primary rachis branch primordia to vegetative shoot.
   Name of original line:      Taichung 65
   Gene locus:      Long arm of chromosome 1
   Remark:      Two recessive alleles, pla2-1 and pla2-2, were identified from M2 population mutagenized with N-methyl-N-nitrosourea.PLA2 encodes MEI2-like RNA-binding protein

GENE REGISTRATION No. 161
   Registrant:      T. Kinae and Y. Nagato
Graduate School of Agricultural and Life Sciences, University of Tokyo, Tokyo 113-8657, Japan
   Gene symbol:      apd1
   Gene name:      apical dicplacement 1
   Character expression:      In a recessive allele, position of shoot meristem is displaced toward the embryo apex due to underdevelopment of scutellum. Multiple radicles are formed.
   Name of original line:      Taichung 65
   Gene locus:      Unknown
   Remark:      Only one mutant allele, apd1-1, has been identified.
   Reference:      Kinae, T., et al. (2005) Plant Sci. 168: 1345-1351

   Registrant:      Y. Inukai1), Y. Shibata1), M. Ashikari2), M.Matsuoka2) and H. Kitano2)
1) Graduate School of Bioagricultural Sciences, Nagoya University, Nagoya, 464-8601, Japan
2) Bioscience and Biotechnology Center, Nagoya University, Nagoya, 464-8601, Japan
   Gene symbol:      crl1
   Gene name:      crown rootless 1
   Character expression:      The recessive mutant, crl1, is defective in crown root formation
   Name of original line:      MNU induced mutant from Taichung 65
   Gene locus:      Located between C725 and R3131 on the short arm of chromosome 3
   Remark:      CRL1 encodes a member of the plant-specific ASYMMETRIC LEAVES2/LATERAL ORGAN BOUNDARIES protein family.

   Registrant:      T. Sazuka, I. Aichi, T. Kawai, N. Matsuo, H. Kitano, M. Matsuoka
Bioscience and Biotechnology Center, Nagoya University, Nagoya, 464-8601, Japan
   Gene symbol:      dbs1
   Gene name:      dwarf bamboo shoot 1
   Character expression:      The recessive mutant, dbs1, shows severe dwarfism and bamboo-like shoot
   Name of original line:      MNU induced mutant from Taichung 65
   Gene locus:      Located near 73.4cM on chromosome 1
   Remark:      DBS1 encodes a NACK-type kinesin-like protein
   Reference:      Sazuka T. et al. (2005) Plant Cell Physiol. 46: 1934-1943.
 
GENE REGISTRATION No. 164
   Registrant:      Masanori Yamasaki, Atsushi Yoshimura & Hideshi Yasui
Faculty of Agriculture, Kyushu University, Fukuoka 812-8581, Japan
   Gene symbol:      Ovc
   Gene name:      Ovicidal
   Character expression:      Dominant allele from Asominori causes ovicidal effect against planthopper eggs
   Name of original line:      O. sativa cv. Asominori
   Gene locus:      Chromosome 6
   Remark:      The Asominori allele at Ovc was essential for increasing egg mortality and responsible for production of benzyl benzoate and formation of watery lesions.
   Reference:      Yamasaki, M., A. Yoshimura and H. Yasui (2003) Mol. Breed. 12: 133-143
Yamasaki M., H. Yasui and A. Yoshimura (1999) RGN16: 94-96.
 
GENE REGISTRATION No. 165
   Registrant:      Kazuyuki Doi and Atsushi Yoshimura
Faculty of Agriculture, Kyushu University, Fukuoka 812-8581, Japan
   Gene symbol:      Ehd1
   Gene name:      Early heading date 1
   Character expression:      Dominant allele from O. glaberrima (IRGC104038) causes early heading.
   Name of original line:      O. glaberrima(IRGC104038)
   Gene locus:      Chromosome 10 (DDBJ AB092509)
   Remark:      Dominant alleles of Ehd1 confer short-day promotion of heading. Taichung 65, a Japonica variety, possesses a recessive allele. Ehd1 encodes a B-type response regulator.
