Research Paper Plant breeding for abiotic & biotic stresses
The effect of salinity stress on Na+, K+ concentration, Na+/K+ ratio, electrolyte leakage and HKT expression profile in roots of Aeluropus littoralis

Masoud Fakhrfeshani; Farajollah Shahriari-Ahmadi; Ali Niazi; Nasrin Moshtaghi; Mohammad Zare-Mehrjerdi

Volume 3, Issue 2 , December 2015, Pages 1-10

  Among abiotic stresses, salinity has been increasing over the time for many reasons like using chemical fertilizers, global warming and rising sea levels. Under salinity stress, the loss of water availability, toxicity of Na+ and ion imbalance directly reduces carbon fixation and biomass production in ...  Read More

The symbiotic effect of Piriformospora indica on induced resistance against bakanae disease in rice (Oryza sativa L.)

Abbas Hajipour; Mohammad-Mehdi Sohani; Valiollah Babaeizad; Hasan Hasani-Kumleh

Volume 3, Issue 2 , December 2015, Pages 11-19

  The root endophytic fungus, Piriformospora indica, colonizes roots of a large number of plant species including Cereals and Brasicaceae. There are several reports indicating that P. indica protects roots from different path- ogens. In the present study, rice plants were pre-inoculated with P. indica ...  Read More

Research Paper Micropropagation & plant breeding
The effect of different concentrations of TDZ and BA on in vitro regeneration of Iranian cannabis (Cannabis sativa) using cotyledon and epicotyl explants

Mehdi Movahedi; Valiollah Ghasemi-Omran; Sepide Torabi

Volume 3, Issue 2 , December 2015, Pages 20-27

  The present study was carried out to investigate micropropagation possibility and determine the optimal medium composition and plant growth regulators (PGRs) combinations under in vitro conditions. The cotyledon and epicotyl explants obtained from 1 month old in vitro grown seedlings were used in MS ...  Read More

The responses of L-gulonolactone oxidase and HKT2;1 genes in Aeluropus littoralis’ shoots under high concentration of sodium chloride

Khalil Malekzadeh; Ali Niazi; Farajollah Shahriari-Ahmadi; Amin Mirshamsi-Kakhaki; Mohammad Zare-Mehrjerdi

Volume 3, Issue 2 , December 2015, Pages 28-35

  Salinity is one of the most important abiotic stresses that limit crop growth and production. Salt stress influences plants in two ways: by affecting ion toxicity and increasing osmotic stress. Ion homeostasis, the excretion of Na+ and using antioxidant systems are the major strategies of salt tolerance ...  Read More

Research Paper Molecular markers & plant breeding
Determination of genetic uniformity in transgenic cotton plants using DNA markers (RAPD and ISSR) and SDS-PAGE

Mohammad-Ali Ebrahimi; Masoud Tohidfar; Mahsa Karimi; Fatehmeh Zawarei

Volume 3, Issue 2 , December 2015, Pages 36-43

  One concern about using transgenic plants is the genetic variation that occurred from theirs tissue culture and regeneration. Molecular markers are an important element for efficient and effective determination of genetic variation. The present work was carried out to assess the genetic uniformity of ...  Read More

Research Paper Molecular biology and (trans) gene expression technology in plant breeding
Proline accumulation and osmotic stress: an overview of P5CS gene in plants

Sahand Amini; Cyrus Ghobadi; Ahad Yamchi

Volume 3, Issue 2 , December 2015, Pages 44-55

  Under osmotic stresses, proline accumulation is an important response of plants to these conditions. Proline is a compatible osmolyte which affects many cellular and molecular aspects of plant in both normal and stressful situations. Proline is shown to be involved in plant development in normal condition ...  Read More
