(Benzo (b) selenienyl-3) acetic acid (BSAA) and its 6-methoxy derivative (M-BSAA) are shown to enhance growth of a sugarbeet callus when replacing 2,4-D as the auxin given together with BAP. Callus grown in the presence of BSAA or M-BSAA produces less ethylene and less polyamines, which supposes an inhibition of both biosynthetic pathways occurring before S-adenosylmethionine. The involvement of ethylene production and polyamines in the control of callus growth, through the control of auxins, is not clear.
