Amino acid sequences of the mitochondrial protein maturase K (matK) and the plastid protein ribulose-bisphos-phate carboxylase (rbcL) from different Amaranthaceae Juss. Species were retrieved from the NCBI (National Center for Biotechnology Information), and used for phylogenetic analysis. A correspondence was found between phylogenetic trees derived from molecular data and those based on palynomorphological data. Clustering patterns in the trees obtained from both protein sequences support the idea of two main pollen types (Amaranthus-type and Gomphrena-type) as described in 1952 by G. Erdtman.
The results also indicate that some species, which according to traditional classification, are from different subfamilies and tribes of Amaranthaceae Juss. may in fact be closely related. Thus molecular data support the idea that palynomorphological data can be used in systematic and phylogenetic studies of Amaranthaceae.

Key words: bioinformatics, maturase K, ribulose-bisphosphate carboxylase, phylogeny, Amaranthaceae, palynomorphology.
