Opines stimulate induction of the vir genes of the Agrobacterium tumefaciens Ti plasmid.

abstract：:Heat, salinity, or osmotic stress influenced protein synthesis in nitrogen-fixing Anabaena sp. strain L-31. Salinity and osmotic stresses were identical and specifically induced 15 polypeptides. Four polypeptides were unique to heat shock, and four other polypeptides were induced under every stress. The results demons...
