Agronomic traits have significant influence on stability and adaptability in maize production. In this investigation, using a population with 266 F2:3 families from Yuyu22 (Zong3 x 87-1), two-location field tests were conducted in Wuhan and Xiangfan in 2001, with a randomized complete block design, to characterize five agronomic traits: ear height, tassel(More)
A genetic linkage map of maize was constructed using 150 SSR and 24 RFLP markers, with F2 population from an elite hybrid (Zong3 x 87-1). Among 174 markers, covering whole maize 10 chromosomes, 49 markers (28.1%) showed the genetic distortion (P < 0.05). Of the total segregation distortion markers, 11 markers (22.5%) deviated toward male parent, Zong3,(More)
The objective of this study was to assess syntenic relationships of quantitative trait loci (QTL) for important agronomic traits between maize and rice based on the comparative genomic map of maize and rice using two F(2:3) populations. Through the comparisons, it was observed that there were extensive conserved relationships of maize QTL affected plant(More)
With plasmid pJP4 (which contains functional gene cluster (tfd) encoding 2,4-D degradation) carrying genetic microorganism Pseudomonas putida SM1443:: gfp2x (pJP4:: dsRed) as the donor strain, events of plasmid mediated gene horizontal transfer and its effect on 2,4-D degradation was investigated in a biofilm system operated under fed-batch mode. The(More)
With a conjugative plasmid pJP4 carrying strain as the donor, two bioaugmentation experiments were conducted in a microcosm biofilm reactor with 2,4-D as the sole carbon source operated in fed-batch mode, and an enlarged lab-scale sequence batch biofilm reactor with mixed carbon sources of 2,4-D and other easily biodegradable compounds, respectively. In the(More)
With pJP4 plasmid carrying genetic engineering bacteria Pseudomonas putida SM1443 :: gfp2x (pJP4 :: dsRed) as the donor, horizontal gene transfer of pJP4 plasmid in 4 isolated pure strains was investigated, and effects of the donor bacteria inoculation on the removal of the target pollutant 2,4-dichlorophenoxyacetic acid (2,4-D) was studied through(More)
Aerobic sludge granules pre-grown on glucose were bioaugmented with a plasmid pJP4 carrying strain Pseudomonas putida SM1443 in a fed-batch microcosm system and a lab-scale sequencing batch reactor (SBR) to enhance their degradation capacity to 2,4-dichlorophenoxyacetic acid (2,4-D). The fed-batch test results showed that the bioaugmented aerobic granule(More)
For 20 amino acids, we reduced the 190 possible pairwise amino acid changes to an elementary set of 75 changes that differ by only one base pair. Based on a Markov Chain Model for substitutions, we developed an Evolutionary Index (EI) which can be computed for each of the 75 elementary changes as the likelihood of substitutions, relative to that of(More)
To investigate gene expression profile in response to aluminum stress and to cloning the key genes related to aluminum tolerance, are crucial to genetic improvement of plant aluminum tolerance. In this study, suppression subtractive hybridization method was adopted to construct SSH-cDNA libraries at seedling stage of two maize inbred lines (Fig. 1), of(More)
