Abstract:
Purification and properties of transcription factor IIIA (TF IIIA) from maize pollen (Zea mays L.) are presented for the first time. The purified protein has a molecular mass of about 35 kDa and exhibits binding affinity toward both 5S rRNA and 5S rRNA gene. It also facilitates transcription of the 5S rRNA gene in a HeLa cell extract.

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...
