Physiological and gene expression responses involved in teak (Tectona grandis L.) seedlings exposed to osmotic and salt stressors.

Background: Teak (Tectona grandis L.) is a forest tree having 2n = 2x = 36 diploid chromosomes. Plants are continually subjected to variety of abiotic stresses due to climate change, which alter their physiological processes and gene expression.

Molecular diversity of Annona species and proximate fruit composition of selected genotypes.

Understanding the genetic variation in germplasm is of utmost importance for crop improvement. Therefore, efforts were made to analyse the molecular marker based genetic diversity of 20 Annona genotypes from five different species of family Annonaceae. During analysis, a set of 11 RAPD primers yielded a total of 152 bands with 80.
