Yao, D. Cohen] Abstract : From interspecific hybridisation in the genus Zantedeschia, we have previously produced albino, variegated and virescent hybrids. The inhibition of chloroplast development in these hybrids is due to plastome-genome incompatibility. The albino hybrids did not develop prolamellar bodies in their etioplasts in darkness and formed only distended membranes, but no grana in light. This indicates that the block to chloroplast development occurs before or during the development of etioplasts. In albino leaf sectors of variegated hybrids, chlorophyll and carotenoid contents were only 2-4% of those in green plants. The mRNA levels for five plastid-development-related genes were also severely reduced, but they were still readily detectable using Northern hybridisation techniques. In the green sectors of variegated hybrids, chlorophyll content and mRNA levels of the fives genes were slightly reduced. We have earlier shown that F1 hybrids between Z. aethiopica and Z. odorata were albino when Z. odorata plastids were present but virescent when Z. aethiopica plastids were present. When the F1 hybrids with Z. aethiopica plastids were backcrossed to Z. odorata, the progeny were albino, virescent or green. Z. odorata plastids were inherited only from maternal parents in the F1 progenies but inherited from either maternal or paternal parents in the backcross. The increased compatibility with, and inheritance of Z. odorata plastids in the backcross suggests that multiple genes play a major role in the plastome-genome incompatibility. An increase in the number of genes from the parent contributing the plastids improves chloroplast development in the hybrids of the genus Zantedeschia.
