Electrophoresis of proteins, especially seed proteins, and karyological studies are useful techniques for determining species and solving the problems of modern taxonomy. The present study was carried out on two species of the Apocynaceae family, Rhazya stricta Decasine and Nerium 01eancder.L. Seed samples of these two genera were taken from the south-east of Iran and SDS-PAGE analysis of th...

Variable indirect photosynthetic rate (P(n)) responses occur on injured leaves after insect herbivory. It is important to understand factors that influence indirect P(n) reductions after injury. The current study examines the relationship between gas exchange and chlorophyll a fluorescence parameters with injury intensity (% single leaf tissue removal) from clipping or Spodoptera eridania Stoll...

background and objectives: many people in ethnic groups of the world have trusted in plants for disease management and cure. medicinal plants have always played a great role in the lives of iranian people in the past and present and with no doubt in the future. healers in different regions of iran have been using medicinal herbs and one rich source for these cures is located in south-west of ir...

The polar lipid classes from thylakoids of Nerium oleander L. were studied with the aim of relating changes in their composition and thermal behavior with reported changes in the transition temperature of their polar lipids and chilling sensitivity of their leaves. With an increase in growth temperature, the transition temperature of phosphatidylglycerol increased from 16 degrees C to 26 degree...
