Abstract
NAD(P)H-dehydrogenases is one of the components of the alternative respiratory pathway having a significant role in varied physiological processes especially under the stress. The plants with a reduced expression of the ndb2 gene were obtained by us for the first time. A significant increase in the expression of genes encoding one of the internal NAD(P)H dehydrogenases - nda2, alternative oxidases - aox1a, aox1d, aox1b and uncoupling proteins ucp1, ucp2 and ucp3 was observed with an increase in the expression level of the ndb2 gene in Arabidopsis plants. If the increase in the expression of the nda2 and aox1a genes was expected, the increase in the expression of the aox1d, aox1b and ucp1-3 genes with increasing ndb2 gene expression is shown for the first time. Moreover, from the point of view of the connection of alternative routes of electron transport with stability, it is important that under the control conditions the over expression of the ndb2 gene causes an increase in the number of transcripts of individual stress genes encoding heat shock proteins (hsp17.6b, hsp17.7 and hsp10), which is also demonstrated for the first time.
