Basic Information
CGSNL Gene Symbol HBD2
Gene Symbol Synonym OsCKI1, CKI, hbd2, CKI1, LTG1, OsCKI1/LTRPK1, LTRPK1, OsLTRPK1
Gene Name Synonym hybrid breakdown 2, rice casein Kinase I, casein kinase I, Low Temperature Growth 1, low-temperature response protein kinase 1
Allele OsCKI1-1, OsCKI1-2, ltg1
Chromosome No. 2
Explanation The homozygotes show abnormal root development, including fewer lateral and adventitious roots, and shorten primary roots as a result of reduced cell elongation. AJ487966. PO:0009005; root ; PO:0020125; elongation zone. GRO:0007047; 02-seedling ; GRO:0007043; 01-germination ; GRO:0007059; 2.01-first leaf through coleoptile. The gene on chromosome 2, designated hybrid breakdown 2 (hbd2), was mapped between simple sequence repeat markers RM3515 and RM3730. GO:0060918: auxin transport.
