Abstract
Detailed analysis of the expression pattern of seven legumain genes from Nicotiana tabacum L. cv. SNN revealed that it showed neither coincidences with the branches of the phylogenetic tree of legumains nor with their conventional assignment to organs. This agreed well with the fact that, so far, no functional differences could be assigned to the sequence differences reflected in the branches of the tree.
Key words: Asn-specific cysteine endopeptidases, gene expression, legumains, seeds, tobacco, vacuolar processing enzyme, vegetative organs
