Project description:Hypoxia, a naturally occurring phenomenon, results in tremendous losses in the growth of plants and in their productivity. On the physiological level oxygen deprivation results in distinct metabolic rearrangements, is accompanied by dehydration, and oxidative and nitrosative stresses. Six to seven core hypoxia-responsive genes, which are always induced under oxygen deprivation, have been shown to include hemoglobin 1 (Hb1) across a wide range of plant species. However, the function of this induced Hb1 is not completely understood .The importance of elevated Hb expression has been attributed mainly to its nitric oxide (NO) scavenging properties, and hence, to the elimination of this free-radical and signaling species. NO is known to accumulate under hypoxia and its level is in reciprocal relationship with the Hb expression levels. However, evidence has accumulated on Hbs as essential for normal plant development and they take part in the regulation of e.g. flowering, germination and lateral and adventitious root emergence. The physiological role of induced hemoglobin (Hb) expression and its role in NO scavenging were assessed by introducing bacterial (Vitreoscilla stercoraria) hemoglobin (VHb) to the cytoplasm and mitochondria of Arabidopsis thaliana. Heterologous expression was chosen to avoid interference with developmental functions of endogenous Hbs. Sixteen day old transformants were subjected to hypoxia or to NO donor treatment (DETA, 500 µM) for 2h and 24h and global changes in gene expression were assessed using a microarray approach. Both hypoxic and NO-treatment experiments were aimed also to reveal novel functions for Hb under abiotic stress conditions, exemplified by oxygen deprivation and NO/oxidative stresses and during normal development of Arabidopsis transformants on the background of normally expressed endogenous Hbs Hypoxia, a naturally occurring phenomenon, results in tremendous losses in the growth of plants and in their productivity.

Project description:The expression of stress-related genes induced by feeding of chestnut moth larvae (Conistra vaccinii L.) was studied with Vitreoscilla hemoglobin-expressing (VHb) and non-transgenic hybrid aspen lines (Populus tremula x P. tremuloides). Besides the herbivore-injured leaves (L1), cDNA microarray analyses were conducted using uninjured leaves of hybrid aspen lines positioned above (A) and below (B) the herbivory exposed leaves.
