In aerobic organisms, protection against oxidative damage involves the combined action of highly specialized antioxidant enzymes, such as copper-zinc superoxide dismutase. In this work, a cDNA clone which encodes a copper-zinc superoxide dismutase gene, named PS-CuZnSOD, has been identified from P. sibiricum Laxm. by the rapid amplification of cDNA ends(More)
Poplar has emerged as a model plant for better understanding cellular and molecular changes accompanying tree growth, development, and response to environment. Long-term application of different forms of nitrogen (such as [Formula: see text]-N and [Formula: see text]-N) may cause morphological changes of poplar roots; however, the molecular level changes(More)
Anthocyanins are important secondary metabolites in plants, which are involved in many functions. The white peel of an enlarged root in 'Tsuda' plants turned red after irradiated with UV-A light for 48 h, but remained white when held in the dark. Red earthnuts and white peels were hybridized with cDNA microarray made by unique gene fragments of subtraction(More)
'Tsuda' turnip (Brassica campestris L. ssp. rapa), in which roots anthocyanin pigmentation is light-sensitive, was used as the material. 'Tsuda' plants were held in darkness or irradiated with sun light and constant light for different time. Anthocyanins in root peel of 'Tsuda' turnip exposed to constant light were identified and quantified with a UV-visual(More)
Using cDNAs prepared from the leaves and stems of Polygonum sibiricum Laxm. treated with NaHCO3 stress for 48 h as testers and cDNAs from unstressed P. sibiricum leaves and stems as drivers library, suppression subtractive hybridization (SSH) was employed to construct a cDNA subtracted library, which contained 2 282 valid sequences including 598 ESTs in the(More)
