Exogenously applied 20-hydroxyecdysone increases the net photosynthetic rate but does not affect the photosynthetic electron transport or the content of photosynthetic pigments in Tetragonia tetragonioides L

Popis výsledku v původním jazyce

Phytoecdysteroids are steroid compounds present in many plant species (sometimes in rather large amounts), but their biological role is still far from being clear. We have found that the exogenous application of 20-hydroxyecdysone (20E) to leaves of Tetragonia tetragonioides L. causes stimulation of its net photosynthetic rate (PN) but does not positively affect the photosynthetic electron transport or the content of photosynthetic pigments. The increase in PN was observed shortly after 20E treatment and was statistically significant during the 4th and 6th hours after treatment but not later, which could be perhaps caused by a strictly short-term window of opportunity for ecdysteroids to significantly affect photosynthetic processes. To our knowledge,these results are the first to suggest a new potential biological function of phytoecdysteroids-regulation of photosynthesis.
