Because FBA is an important enzyme involved in the Calvin cycle, improving the activity of the enzyme could certainly boost CO 2 concentrations in plant green tissues. Class I FBAs are not inhibited by ethylene diamine tetraacetic acid EDTA or affected by potassium ions, and occur in some bacteria, archaea, higher plants, and animals Penhoet et al. The results revealed the complicated expression patterns of the TaFBA gene family in response to various abiotic stresses Figure 8.

Each subgroup contained five wheat relative FBA genes, except for six in class Ie. Because TaFBA genes mostly possess multiple phytohormone and abiotic stress-responsive elements, we considered that the expression pattern of TaFBA genes could be regulated by various environmental factors. Autotrophic carbon fixation in archaea. The other copy appears to be the result of a chromalveolate-specific gene duplication.

Fructose-bisphosphate aldolase class-I active site (IPR) < InterPro < EMBL-EBI

Annotation of transposable elements on TaFBA genes. Distribution of fructose diphosphate aldolase variants in biological systems. Isolation of a novel fructose- 1,6-bisphosphate aldolase gene from codonopsis lanceolata and analysis of the response of this gene to abiotic stresses. For the investigation of the molecular evolution of the TaFBA gene family, 31 FBA genes from other closely related wheat species were identified: Blue circle represents TACK group.


Views Read Edit View history. The exon and intron sizes can be estimated using the scale at the bottom. Class I plastid FBA appears to have been acquired by chromalveolates from a red algal endosymbiont, whereas one copy of class II plastid FBA is likely to have originated from an ancient green algal endosymbiont. A total of 21 TaFBA genes were localized to 12 chromosomes of 4 homoeologous groups: Pleiotropy modulates the efficacy of selection in Drosophila melanogaster.

Lateral transfer and recompartmentalization of Calvin cycle enzymes of plants and algae. The evolutionary study on plant FBA genes is useful in investigating the origin of chloroplast and photosynthetic genes. Sonalika against Fusarium induced oxidative stress. Evaluation of four microbial Class II fructose 1,6-bisphosphate aldolase enzymes for use as biocatalysts.

Exons are shown as Double-sided wedges, and different colours indicate different FBA gene groups. A conserved glutamate residue exhibits multifunctional catalytic roles in D-fructose-1, 6-bisphosphate aldolases.

Fructose-bisphosphate aldolase – Wikipedia

Genome plasticity a key factor in the success of polyploid wheat under domestication. Pink circle represents terrabacteria group. From Wikipedia, the free encyclopedia.

The aldolase used in gluconeogenesis and glycolysis is a cytoplasmic protein. Pairwise alignments of FBA genes of wheat and wheat relatives.

Total RNA was isolated from etiolated two-leaf seedling at 0, 1, 4, and 8 h after exposure to light. Cytosolically localized FBAs in P.

Chuang Ma for the manuscripts review and good suggestion. Green circle represents viridiplantae. Crystal structure of human muscle aldolase complexed with fructose 1,6-bisphosphate: This observation was consistent with models of interline age hybridization in the Triticeae Escobar et al. II Demonstration of aldolase types in photosynthetic organisms.


Cloning and molecular characterization of fructose-1,6-bisphosphate aldolase gene regulated by high-salinity and drought in Sesuvium portulacastrum. Nulli-tetrasomic Chinese Spring genotypes contain four copies of one chromosome pair tetrasomic to compensate for the lack of a homoeologous chromosome pair nullisomic Sears et al.

The two classes are often present together in the same organism.

Putative cis-acting regulatory DNA elements in the promoter sequences 1. The fructose-bisphosphatw in expression profiles are indicative of the multiple functions of different TaFBA genes, and FBAs might play a more complicated role histofy the regulation of glycolysis and carbon concentration. The organization number, order, and length of the exons were mostly conserved within different FBA groups, whereas the introns and UTRs showed variable lengths and distribution.

Although, class I TaFBAs had the same catalytic residue sequences, different conformations in the active sites would affect the spatial structures Figures 4G,H. Pairwise alignments of TaFBA genes.

In glycolysis fructose 1,6-bisphosphate is made into glyceraldehydephosphate and dihydroxyacetone phosphate through the use of aldolase. It furthers the University’s objective of excellence in research, scholarship, and education by publishing worldwide. Each member of the FBA gene family might thus have different biochemical activity. The cone opsin repertoire of osteoglossomorph fishes: PCR amplification was performed as follows: FBA genes have been shown to be involved in various important physiological and biochemical processes, e.

Additionally, tyrosine residues are crucial to this mechanism in acting as stabilizing hydrogen acceptors. Retrieved from ” https: Bioinformatics analysis and data processing:
