[Effects of cumulative polymery of tomato ripening genes]
Abstract:
Results of investigation of hetero- and homozygous interconnection of tomato keeping quality genes alc, nor, rin are presented. In double heterozygotes alc/alc+//nor/nor+, nor/nor+//rin/rin+, and alc/alc+//rin/rin+ a cumulative polymery resulting in formation of a new "ong-ripening", phenotype was observed. In the case of non-allelic interconnection in double homozygotes alc/alc//rin/rin, nor/nor//rin/rin, and alc/alc//nor/nor considerable inhibition of ripening processes takes place accompanied by suppression of carotenoid synthesis which favours formation of a new "on-ripening" phenotype with green-white colour of a fruit.

Molecular Weight of Step-Growth Polymers
As the step-growth polymerization involves step-wise condensation of monomers, the molecular weight also builds up eventually. Consequently, high molecular weight polymers are obtained at the late stages of the polymerization, where 99% of monomers have been consumed.

Transgenic Plants
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
