Cryoimmobilized anther analysis reveals new ultrastructural insights into Rhynchospora (Cyperaceae) asymmetrical microsporogenesis [PDF]
IntroductionThe Cyperaceae family is distinguished by holocentric chromosomes and a distinctive microsporogenesis process, which includes inverted meiosis, asymmetric tetrad formation, selective cell death, and the formation of pseudomonad pollen ...

Interspecific somatic hybrids between Solanum bulbocastanum and S. tuberosum and their haploidization for potato breeding [PDF]
Protoplast fusion between incongruent Solanum bulbocastanum and S. tuberosum haploids was accomplished to produce hybrids combining elite traits from both parents. We identified 11 somatic hybrids out of 42 regenerants analyzed through ISSR markers. Some

A Review of the Developmental Processes and Selective Pressures Shaping Aperture Pattern in Angiosperms [PDF]
Pollen grains of flowering plants display a fascinating diversity of forms. The observed diversity is determined by the developmental mechanisms involved in the establishment of pollen morphological features.

Using a wheat line with wild emmer genetic material to improve modern Triticum aestivum L. varieties by a complex of economically useful traits [PDF]
Wild emmer Triticum dicoccoides samples have a high content of protein and microelements in their grain, but when crossed with common wheat varieties, undesirable properties of a wild relative (low yield, spike fragility and difficult threshing) can be ...

Evaluation of mitotic activity in tapetal cells of grapevine (Vitis L.)
The knowledge with reference to the grapevine tapetum has been centered on its anatomy/morphology and hardly anything at all is known about its mitotic activity throughout the microsporogenesis. The aim of this study was to ascertain the mitotic activity

Evaluation of the course of microsporogenesis in some selected peach (Prunus persica L./Batsch) cultivars [PDF]
The evaluation of the microsporogenesis process was performed from January to April within the period of 2011-2013. The experiment involved 15 peach cultivars and the control cultivar Redhaven. The course of microsporogenesis was evaluated on the base of

Flower bud development of almond cultivars based on three different methods
Flower bud development of fruit trees plays a key role in their climatic adaptation. It is closely related to dormancy release that determines winter frost susceptibility. Detailed characterisation of flower bud development of 25 almond (Prunus amygdalus
