In this review, we discuss the multiple definitions of 'drought tolerance' and the biological processes in...

Clonal propagation by somatic embryogenesis (SE) has a great application potential in conifers, but its efficiency still needs further improvement. Quantitative PCR (qPCR) is widely used for gene expression analysis during SE as part of studies to characterize gene function. In qPCR, data is normalized against a reference gene with a uniform expression during the tested conditions. Studies have...

We quantified the taxonomic, functional, and phylogenetic diversity of fungi associated with dead moss tissues conifer needles in a forest-tundra ecotone sub-Arctic region, Quebec, Canada. detected 615 operational taxonomic units, total, 84 families 97% sequence similarity by metabarcoding internal transcribed spacer 1 (ITS1) region nuclear ribosomal DNA. Saprotrophs were dominant functional gu...

the essential oils obtained from fresh fruits and terminal branchlets with adherent leaves of cupressus sempervirens l. cv. cereiformis rehd. growing in iran, were analyzed by gc-ms, and screened for bacteriostatic and fungistatic activities. thirteen components were identified in the essential oils. the main constituents of both fruits and leaves were ?-pinene, æ-3-carene, ?-terpenyl acetate a...
