Effective (nitrogen-fixing) root nodules of Oxytropis maydelliana Trautv., O. arctobia Bunge and Astragulus alpinus L. were collected in the high Arctic tundra and subsequently processed for structural studies. The cylindrically-shaped perennial nodu

The goal of opening wedge high tibial osteotomy (HTO) is to reduce excessive loading on the medial compartment of the knee by correcting varus deformity, thereby reducing pain and improving function. Although surgical outcome is reportedly poor in ca

Plant tissue culture media, sterilized through commercial filter membrane units, inhibited plant cell growth and development. Embryogenesis was suppressed in microspore cultures of Brassica napus and anther cultures of Triticum aestivum, and in vitro

It is currently accepted that 'stress' triggers induction of microspore embryogenesis, and for Brassica napus L. cv. Topas it is heat-shock. It has been postulated that the heat-shock proteins (HSPs) generated during heat stress have a central role i

Transgenic Nicotiana tabacum L. (tobacco) plants expressing an unregulated gene for pyrophosphate-dependent fructose-6-phosphate 1-phosphotransferase (PFP) from the fermentor protist Giardia lamblia were produced. Independently transformed lines reve

Changes in the actin filament and microtubule cytoskeleton were examined during heat- and cytochalasin D-induced embryogenesis in microspores ofBrassica napus cv. Topas by rhodamine phalloidin and immunofluorescence labelling respectively. The nucleu

Pea (Pisum sativum) root nodule cells infected by the diazotrophRhizobium leguminosarum have been well characterized by chemical fixation techniques. Propane-jet freezing and high pressure freezing were used in this study to compare rapidly frozen an

Prior to this report, heat treatment (32.5°C, 24 h) was the method used to induce embryogenesis fromBrassica napus microspores. Continuous culture at 25°C results in pollen development. This study shows that colchicine alone, at the non-inductive t
