A wedge-shaped anterior hairline extension associated with a tessier number 10 cleft.

A wedge-shaped anterior hairline extension is a very rare skin manifestation usually associated with congenital anomalies including a Tessier number 10 cleft. Other associated conditions are the Tessier number 9 cleft, the Fraser syndrome, and the Manitoba oculotrichoanal syndrome (MOTA syndrome). The Tessier number 10 cleft features include a coloboma of the middle third of the upper eyelid, and an eyebrow divided into two portions.

Successful genetic transformation of Chinese cabbage using phosphomannose isomerase as a selection marker.

A mannose selection system was adapted for use in the Agrobacterium-mediated transformation of Chinese cabbage. This system makes use of the pmi gene that encodes phosphomannose isomerase, which converts mannose-6-phosphate to fructose-6-phosphate. Hypocotyl explants from 4-5-day-old seedlings of Chinese cabbage inbred lines were pre-cultured for 2-3 days and then infected with Agrobacterium.
