| Notes | 44-1267/S rice（Oryza sativa）; OsPIN1b; negative phototropism XU Hua-wei;WANG Hai;MO Yi-wei（ 1. College of Agriculture, Henan University of Science and Techen.ology, Luoyang 471003, China; 2. School of Life Sciences, Shaoxing University, Shaoxing 312000, China ） Earlier research results showed that rice auxin efflux protein OsPIN1 a probably participated in regulating negative phototropism of rice roots. To explore the relationship between other OsPIN genes and negative phototropism of rice roots,gene-specific primers were used to amplify Os PIN1 b gene by RT-PCR based on the OsPIN1 b sequence in Gen Bank. Sequencing result showed that the full ORF was obtained（1 665 bp）. Bioinformation analysis showed that the sequence was 100% identity with the reported sequence,the GC content of OsPIN1 b ORF was 64.08% and OsPIN1 b encoded 554 amino acid residues. The OsPIN1b-green fluorescent protein（gfp）fusion expression vector p CAMBIA-1301-Os PIN1b∷GFP was constructed and transformed into Japonicarice Zhonghua11 by Agrobac |
