Abstract:
... We tested autumn frost hardiness in three Norway spruce (Picea abies [L.] Karst.) provenances originating from different altitudes at two trial plots in Slovakia (Vel'ký Lom at 450 m a.s.l., Mútne-Zákamenné at 1,250 m a.s.l.) in a spinoff experiment of the IUFRO 1964/68 Inventory Provenance Experiment with Norway spruce. Two approaches were used to assess hardiness: the electrolyte-leakage method ...

Arabidopsis; antioxidants; chlorophyll; copper; enzyme activity; gene overexpression; genes; laccase; microRNA; nutrient deficiencies; peroxidase; plant response; proteins; root growth; seedlings; superoxide dismutase; tobacco; transgenic plants
Abstract:
... MicroRNA miR408 is predicted to target the transcripts for the copper proteins plantacyanin and laccase in Arabidopsis. In this study it was found that miR408 is present in tobacco also. Its accumulation was positively induced by copper deficiency, providing additional evidence for the important role of miR408 in plant responses to nutriment conditions. To examine the functions of miR408 in tobacc ...

Subject:
Acyrthosiphon pisum; Medicago sativa; Pisum sativum; Trifolium pratense; Vicia faba; chlorophyll; leaves
Abstract:
... We determined the chlorophyll a and b levels (SPAD readings) in uninfested leaves and in leaves after 7 and 17 days of aphid infestation in four Fabaceae species (Pisum sativum L., Vicia faba L., Trifolium pretense L, Medicago sativa L.). Feeding by pea aphids Acyrthosiphon pisum Harris (Hemiptera: Aphididae) caused significant loss of chlorophyll a and b in the infested plants. Uninfested leaves ...
