ON THE PROGENY OF DIPLOID × TRIPLOID POPULUS TREMULA

Running title: Multi-locus polymorphism in Populus tremula Keywords: demography, linkage disequilibrium, nucleotide polymorphism, Populus tremula Multilocus patterns of nucleotide polymorphism and the demographic history of Populus tremula

I have studied nucleotide polymorphism and linkage disequilibrium using multilocus data from 77 fragments, with an average length of fragments 550 bp, in the deciduous tree Populus tremula (Salicaceae). The frequency spectrum across loci showed a modest excess of mutations segregating at low frequency and a marked excess of high frequency derived mutations at silent sites, relative to neutral e...

Comparative Proteomic Analysis of Mature Pollen in Triploid and Diploid Populus deltoides

Ploidy affects plant growth vigor and cell size, but the relative effects of pollen fertility and allergenicity between triploid and diploid have not been systematically examined. Here we performed comparative analyses of fertility, proteome, and abundances of putative allergenic proteins of pollen in triploid poplar 'ZhongHuai1' ('ZH1', triploid) and 'ZhongHuai2' ('ZH2', diploid) generated fro...

Simultaneous formation of haploid, diploid and triploid eggs in diploid-triploid mosaic loaches

Effect of thermal stress on some hematological parameters of diploid and triploid Rainbow trout (Oncorhynchus mykiss)

Temperature fluctuation is one of the most common stressors during fish transportation and aquaculture condition. Triploid rainbow trout (Oncorhynchus mykiss) get more attention because of its sterility. In this study, 24 rainbow trout belong to diploid and triploid group, average weight 13±0.23 g were subjected to temperature change from 13 to 20 ºC, and kept under tension for 10 min. Before a...
