Plant genomes appear to exploit the process of gene duplication as a primary means of acquiring biochemical and developmental flexibility. Thus, for example, most of the enzymatic components of plant secondary metabolism are encoded by small families of
sequences from the sugarcane expressed sequence tag (sucest) database were analyzed based on their identities to genes encoding chalcone-synthase-like enzymes. the sorghum (sorghum bicolor) chalcone-synthase (chs, ec 2.3.1.74) protein sequence (gi|12229613) was used to search the sucest database...
Soybean is a paleopolyploid that has undergone two whole genome duplication events. Gene duplication is a type of genomic change that can lead to novel functions of pre-existing genes. Chalcone synthase (CHS) is the plant-specific type III polyketide syn
(ACS), and apyronesynthase (2PS); all of these proteins share about 65-70% identity withCHS. The properties of several otherenzymessuggest that they are members of the protein family, and precursor feeding studies suggest that the number may be much larger than suspected so far. The ...
Introduction of a Chimeric Chalcone Synthase Gene into Petunia Results in Reversible Co-Suppression of Homologous Genes in trans. We attempted to overexpress chalcone synthase (CHS) in pigmented petunia petals by introducing a chimeric petunia CHS gene. Unexpectedly, the introduced ge......
Chalcone is an aromatic ketone that forms the central core of many important biological compounds, which are known as chalcones. Chalcones are the biogenetic precursors of flavonoids and isoflavonoids, which are abundant in plants. Chalcones are active lead molecules in medicinal chemistry for the disc...
Chalcone synthase (CHS) gene was cloned from the petals of Gerbera hybrida using RT-PCR method in our experiment. The sequence of the cDNA coding region was 1 197 bps, encoding a protein of 398 amino acids sharing 99% identical to CHS1 cDNA reported by Helariutta. The gene was fused in...
(FAPs) and a plant protein family with no isomerase activity (CHILs). Ancestral inference supported the evolution of CHI from a protein lacking isomerase activity. Further, we identified four alternative founder mutations, i.e., mutations that individually instated activity, including a mutation ...
1.Chalcone synthase (CHS) gene was cloned from the petals of Gerbera hybrida using RT-PCR method in our experiment.利用RT-PCR方法,从非洲菊(Gerberahybrida)花瓣的cDNA中克隆到了查尔酮合酶(ChalconeSynthase,CHS)基因CHS,进行了序列分析。 2.The chalcone synthase cDNA in Phalaenopsis ( pchs -1), wh...
