Planntas these branches were supported by high bootstrap values. The Accession numbers of the sequences used to construct the phylogenetic tree were: What Are the Functions of Photosynthesis? J Plant Nutr 5: This enzyme is widely distributed in plants, algae, and bacteria, but is absent from animals, fungi, and yeast Lepiniec et al.

AtPPC2 appears annotated with a deletion of 41 residues due to the mis-annotation of sequence that corresponds to exon 9, according to our cDNA data, as intron sequence. Surprisingly, no phosphorylation domain was found in the polypeptide deduced from the Atppc4 gene Fig. Laporan c3, c4, Dan Cam Documents.

BMC— and predoctoral fellowship fotosibtesis R. J Mol Evol For each gene Atppc1Atppc2Fotosntesisand Atppc4 from Arabidopsis and Osppc1Osppc2and Osppc-b from ricethe linear range of amplification was determined to establish the number of cycles of the PCR reactions.

The plant-type PEPC genes, which possess the regulatory mechanism of phosphorylation, form a homogeneous cluster in the phylogenetic tree Fig. Open in a separate window. Nucleic Acids Res The polypeptide deduced from Osppc-b included in the comparison of Fig. In vivo, the active enzyme acts as a homotetramer composed by subunits of to kD O’Leary, The carbon dioxide then undergoes the Calvin cycle, as in C3 photosynthesis.

Numbers in branches indicate bootstrap values percent.

It should be mentioned that Atppc4 is expressed at a lower cwm than the other PEPC genes, as shown by the higher number of cycles needed to obtain the linear range of amplification in the RT-PCR analysis 26 for Atppc1, Atppc2and Atppc3 and 32 for Atppc4.

Sequence alignment of PEPC from different sources. An important question addressed in this analysis was to establish whether or not Atppc4the bacterial-type gene, is expressed. Systems of Photosynthesis Pima Community College: Plantae analysis revealed the expression of the bacterial-type Osppc-b gene both in seeds mature seeds and aleurone and scutellum from seeds after 5 d of imbibition and in roots and shoots from 5-d-old seedlings Fig.


Multiple alignment of complete amino acid sequences of PEPC from different plant and bacterial sources accessible from public databases and genome projects was performed with the ClustalX version 1. This alignment was used to construct the phylogenetic tree with the neighbor-joining method using the ClustalX version 1.

We have not found PEPC genes after searching the archaeobacteria genomes accessible in public databases. Fotosintesis c3 c4 Cam Download Report. Depending on which text editor you’re pasting into, you might have to add the italics to the site name. CAM is an abbreviation of crassulacean acid metabolism.

The average size of introns is larger in Osppc-b than in Atppc4. Bootstrap analysis was computed with 1, replicates and excluding positions with gaps. The pair of primers were:
