Comparison of structure and numbers of genes among cereals
Published 2005-03-01Get full textThis review describes the current state of knowledge regarding cereal genome structure. Annotation based on the sequencing of long genomic segments from cereals and the whole-genome analyses of Arabidopsis and rice, suggests that a mosaic structure consisting of recombinationally active gene-rich is...

Comparison of MADS transcriptional factor on codon bias in arabidopsis and rice
Published 2005-09-01Get full textMost of the flower development-related functional genes are belong to MADS transcription factors families. Through the factorial correspondence analysis (FCA) of CodonW, we can find out that MADS transcriptional factors in Arabidopsis prefer to A-ending and U-ending codons, while that in rice prefer...

Phenotypic characterization of K2 generation of Peiai64S transgenic rice transformed with Xa21 gene
Published 2001-11-01Get full textThe resistance to bacterial blight and agronomy characteristic were observed for the R2 generation of transgenic plants from Peiai64S. The results showed that most of transgenic plants have higher resistance to Xanthomonas oryza pv. oryzae than that of the control (Peiai64S). A special marker band o...

Breeding of fine quality CMS line Jiazhe A
Published 2001-09-01Get full textJiazhe A is a WA-type fine quality indica CMS line developed successively through crossing Jiazhe B (No: Y33) to Zhenshan 97A and backcrossing with Jiazhe B as the recurrent parent. It was technically certified in Zhejiang in July 1999. Quality indexes of JiazheA were analyzed and six of ten indexes...

Introduction of soybean glycinin gene into rice (Oryza sativa L.) with Agrobacterium-mediated transformation
Published 2001-09-01Get full textBased on the previous work of cloning of upstream sequence of a rice glutelin gene Gt1, an Agrobacterium binary vector based on pCAMBIA1301 was reconstructed with a soybean glycinin gene-directed by the tissue specific promoter, and was used in rice transfomation. The target gene was successfully in...

Effects of S-3307 and PP333 on callus induction and plantlet regeneration of tall fescue tall fescue (Festuca arundinacea Schreb)
Published 2004-01-01Get full textEffects of synthetic plant growth regulators S-3307 and P333 on tissue culture of tall fescue (Festuca arundinacea Schreb.) were highly correlated with genotypes. Both the concentrations of S-3307 used in the experiment (0.01 mg/L and 0.1 mg/L) led to an increase in the callus induction rate in the...

Genetic analysis of agronomic traits of two doubled haploid populations in tobacco
Published 2004-09-01Get full textWith two DH populations derived from anther culture in tobacco, the heritability analysis of six quantitative traits, i. e. plant height, the number of leave, lumbar leaf length and width, internodal length and pericaulome length, were made. Based on their skewness and kourtosis values of two popula...

Comparative studies on stem anatomical structure of rice plants with various ploidy level
Published 2009-09-01Get full textTo investigate the effects of ploidy changes on the stem structure, by using flow cytometry (FCM), we distinguished six different ploidy materials (haploid, diploid, and triploid of line FC311 and haploid, diploid, and tetraploid of line FC322), in rice (Oryza sativa L. subsp. Japonica). Also, we co...
