Title: Rice embryo globulins : amino-terminal amino acid sequences , cDNA cloning and expression .
Author: Sun JL Nakagawa H Karita S Ohmiya K Hattori T
Journal: Plant Cell Physiol . Citation: V : 37 ( 5 ) P : 612-20 Year: 1996 Type: ARTICLE
Literature: oryza Field: abstract Doc ID: pub8819309 Accession (PMID): 8819309
Abstract: A globulin fraction prepared from rice embryos contained polypeptides or polypeptide groups of 49 kDa ( designated REG1 ) , 46 kDa ( designated REG2 ) , about 35 kDa , 32 kDa and 25 kDa . The amino-terminal sequences of REG1 and the major polypeptide in the 35-kDa group were identical , suggesting that the REG1 polypeptide undergoes partial proteolytic processing that removes a carboxy-terminal region . A cDNA clone , designated pcREG2 , encoding REG2 was isolated , and its nucleotide sequence was determined . The deduced amino acid sequence of REG2 was found to be 68% identical to that of the maize GLB2 globulin . Reg2 mRNA was present at high levels during embryo development for up to 14 days after flowering ( DAF ) . Lower levels were found 20 DAF when the maturation of embryos was almost completed , and at the dry mature stage . Reg2 mRNA almost disappeared upon imbibition of isolated dry mature embryos but it was re-induced at a low level by further treatment with ABA . The expression of Reg2 was not induced by ABA in suspension-cultured cells , unlike that of Osem , one of the late embryogenesis abundant protein ( LEA ) genes .

Title: Proteomic analysis of rice embryo : an approach for investigating Galpha protein-regulated proteins .
Author: Komatsu S Abbasi F Kobori E Fujisawa Y Kato H Iwasaki Y
Journal: Proteomics Citation: V : 5 ( 15 ) P : 3932-41 Year: 2005 Type: ARTICLE
Literature: oryza Field: abstract Doc ID: pub16152656 Accession (PMID): 16152656
Abstract: The rice dwarf1 ( d1 ) mutant , which lacks the alpha subunit of a heterotrimeric G protein ( Galpha protein ) , shows abnormal morphology due to shortened internodes , dark green leaves and grains that are small and round . Proteome analysis was used in this study to aid in determining the function of Galpha protein in rice embryos . Using 2-DE , seven seed embryo proteins were shown to be down-regulated in the d1 mutant as compared with its wild type . These seven proteins included a receptor for activated C-kinase ( RACK ) and six rice embryo globulin-2 proteins ( REG2 ) . The six REG2 have similar molecular masses with minor differences in pI . In addition to the reduced accumulation of RACK in the d1 mutant , the increase in QL/d1 , in which a constitutively active form of the Galpha protein is expressed , was significantly higher as compared with wild type . The level of accumulation of these seven proteins during seed development and maturation did not change significantly until the 2nd wk after pollination . Reduced accumulation of these seven proteins started in the d1 mutant at the 3rd wk after pollination , and continued until seed maturation was complete . All seven proteins were completely absent 24 h after imbibition in both d1 mutant and its wild type . However , the phytohormone abscisic acid promoted the expression level of RACK after imbibition in the wild type as compared with d1 mutant . These results suggest that RACK is regulated by Galpha-protein and plays an important role in a basic cellular process as well as in rice embryogenesis and germination .
