The impact of heat stress targeting on the hormonal and transcriptomic response in Arabidopsis

Popis výsledku v původním jazyce

Targeting of the heat stress (HS, 40 oC) to shoots, roots or whole plants substantially affects Arabidopsis physiological responses. Effective stress targeting was proved by determination of the expression of HS markers, HsfA2 and HSA32, which were quickly stimulated in the targeted organ(s), but remained low in non-stressed tissues for at least 2 h. When shoots or whole plants were subjected to HS, a transient decrease in abscisic acid, accompanied by a small increase in active cytokinin levels, was observed in leaves, consistent with stimulation of transpiration, the main cooling mechanism in leaves. HS application targeted to part of plant resulted in a rapid stimulation of expression of components of cytokinin signaling pathway (especially of receptor genes) in the non-exposed tissues, which indicated fast interorgan communication. Under all HS treatments, shoot apices responded by transient elevation of active cytokinin contents and stimulation oftranscription of genes involved in
