Promotion of respiration by auxin in the induction of cell division in suspension culture

Auxins (IAA, NAA, p-CPA) caused 20-30% promotion of respiration of auxin-dependent cell cultures of Nicotiana tabacum , Glycine max , Taraxacum mongolica , and Atriplex sp. and had small if any effect on respiration of auxin-independent cell cultures of Rubus sp. and Scorzonera hispanica . Antiauxin...

Beschreibung
Zusammenfassung:	Auxins (IAA, NAA, p-CPA) caused 20-30% promotion of respiration of auxin-dependent cell cultures of Nicotiana tabacum , Glycine max , Taraxacum mongolica , and Atriplex sp. and had small if any effect on respiration of auxin-independent cell cultures of Rubus sp. and Scorzonera hispanica . Antiauxin (p-CPIBA) did not affect the respiration. It is concluded that the promotion of respiration is a common event for the auxin effects both on cell extension and on cell division. This promotion is necesary for the induction of cell division and is exerted via direct activation of mitochondria in situ.
