Abstract:
With 0.4 g l(-1) arachidonic acid (AA) added to the medium after 36 h fermentation, β-carotene production in mated cultures of Blakeslea trispora was 73 % higher than that of the control at 690 mg l(-1). With the treatment of AA, the transcriptional levels of genes hmgR, carRA and carB, that are involved in carotene biosynthesis, increased by 31, 22 and 39 %, respectively.

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...
