New strategies for breeding seedless plants have been proposed by using these genes. These include expression of some cytotoxin genes or genes for production of hormones in plants under the control of seed_coat_specific promoter or ovary_specific promoter and "terminator technology" etc. It's clear that these transgenic methods will be introduced into a wider range of fruit and vegetables in the future.

Result Based on directly regenerated plant of in vitro plant of Xinjiang cotton, the cotton epicotyl treated by pre-culture for 3-5 d was immersed in bacteria for 15 min and co-cultured for 2 d. Cephalothin at 100 mg/L was used to inhibit bacteria after 50 mg/L kan selection. And the combination of cytokinin with relatively high content and auxin with low content was used in its directly budding culture to obtain resistant seedlings.
