IAA is synthesises by tryptophan and is primarily synthesized in a two-step process 

Indole-3-pyruvate (IPyA) as the intermediate. 

The second step in the pathway is carried out by the YUCCA gene product, a tryptophan aminotransferase.

Dictyostelium can utilize one of three survival strategies when food starvation-

 Microcyst formation, favoured in dark & wet conditions, or ammonia levels are high.

 Zygote formation, favoured in dark & wet conditions, & is triggered by ethylene produced by the cells.

Nonsense mutations release ribosomes within the RNA of a multigene operon, though, enabling rho to terminate transcription prematurely and prevent expression of distal genes in the transcription unit even though their open reading frames contained wild-type sequences
