Regulation of a dominant glutathione S-transferase and Na+/K+ by spermidine under salinity in onion

Spermidine (Spd) is one of the most important polyamines (PAs) showing important roles in growth, development and stress responses in plants. The role of Spd in regulation of a dominant glutathione S-transferase (GST, E.C.2.5.1.18) and ionic balance of Na+ and K+ in onion leaves were examined. Onion GSTs were separated from fresh bulb tissue using DEAE-cellulose chromatography. Three GSTs were eluted at 56, 120 and 169...

Genetic structure of cassava populations (Manihot esculenta Crantz) from Angola assessed through (ISSR) markers

Eighteen ISSR primers (between Simple Repeated Sequences) were used to estimate the genetic diversity of Angolan cassava populations in order to identify genetic variabilities and their potential to be used in the diversification of cassava crops in Angola. In order to do so, three populations from three Angolan provinces were analyzed (Cuanza Norte, Uige and Malanje), which totaled 40 genotypes. In total, 116 bands...
