The Caspian lizard (Darevskia caspica) is a recently described endemic of the Hyrcanian forests Northern Iran. paper presents new data on reproductive biology D. caspica obtained in laboratory conditions. Breeding females have body length 53.4– 64.4 mm and mass 2.96–3.60 g. Females produce from one to three clutches per season, each which contains 1–6 eggs. these eggs 10.35–13.95 mm, width 6.19...

BACKGROUND Homeodomain-leucine zipper (HD-ZIP) proteins are plant-specific transcriptional factors known to play crucial roles in plant development. Although sequence phylogeny analysis of Populus HD-ZIPs was carried out in a previous study, no systematic analysis incorporating genome organization, gene structure, and expression compendium has been conducted in model tree species Populus thus f...

BACKGROUND Populus is a model woody plant and a promising feedstock for lignocellulosic biofuel production. However, its lengthy life cycle impedes rapid characterization of gene function. METHODOLOGY/PRINCIPAL FINDINGS We optimized a Populus leaf mesophyll protoplast isolation protocol and established a Populus protoplast transient expression system. We demonstrated that Populus protoplasts ...

poplar trees are appropriate species for plantation and forest rehabilitation because of fast growing and high wood yield, as well as adaptability to unfavorable climate. salinization of soil and high temperature are the inhibitory factors in khuzestan province. populus euphratica is a tree species that tolerates soil salinity and high temperature. acclimatization of cut seedling of three popul...
