“…Whereas attempts to produce hybrids within and between species of Portulaca have been numerous (Rizvi et al 1971;Singh 1979;Steiner 1944;Syakudo et al 1960;Tjebbes 1930), apparently only one interspecific hybrid (P. centrali-africana x P. kermesina) has been reported (Bouharmont 1965), and this did not involve taxa occurring in Hawaii. The only available comparative information on the biology of Hawaiian Portulaca is found in the revision by Geesink (1969), which dealt with morphology, systematics, biosystematics, and typification of Portulaca from Indo-Australia and the Pacific.…”

Light-inducible pigmentation in Portulaca callus; selection of a high betalain producing cell line

et al. 1991

View full text Add to dashboard Cite

We have established a unique betalain pigmentation system in callus cultures that originated from seedlings of Portulaca sp. 'Jewel'. Within three different 'Jewel' lines examined, one line (JR) was clearly superior with regard to callus growth rate and pigment formation. Furthermore, after ten cycles of selection of deeply colored callus patches, the selected clones contained on an average four times the amount of betalain as compared to the non-selected mother line. The colorization was induced by light, but disappeared in the dark. Pigment synthesis was detectable within 30 h after irradiation and showed positive correlation with irradiation periods.
