En Oxalis tuberosa, 'oca', se ha purificado la ocatina, que constituye 40% a 60% de la proteina total soluble de los tuberculos de oca; tiene un peso molecular aparente de 18 kDa y se ha demostrado que inhibe en crecimiento de varias bacterias fitopatogenicas y de hongos (15).
Esta caracteristica es inusual y no se ha encontrado en los mapas electroforeticos bidimensionales de otros cultivos andinos, como Solanum tuberosum 'papa' (16) y Oxalis tuberosa 'oca' (15).
The Oxalis tuberosa alliance is an informal name first proposed by de Azkue and Martinez (1990) for a group of morphologically similar Oxalis species that share a base chromosome number rare in the genus (x = 8).
The Oxalis tuberosa alliance has been confirmed as monophyletic in molecular studies that use DNA sequences of two nuclear loci, the internal transcribed spacer region (ITS) of nuclear ribosomal DNA (Tosto & Hopp, 1996; Emshwiller & Doyle, 1998b), and the chloroplast active (but nuclear encoded) isozyme of glutamine synthetase ncpGS) (Emshwiller & Doyle, 1998a, 1999; Emshwiller, 1999a).
