Acta Societatis Botanicorum Poloniae, 2015 The process of microsporogenesis and development of pollen grains was found to occur in an identical rhythm in 14 examined forms of Pisum sp. as compared with the development of the perianth. In the 3 forms studied in detail: Pisum sativum L.

Disturbances in microsporogenesis and pollen grain development in Gagea lutea (L.) Ker. Gaw.
Acta Agrobotanica, 2012 The meiotic division of microsporocytes and pollen grain development in Gagea lutea (L.) Ker.-Gaw. (Liliaceae) with fluorescence microscope (excitation light 400 nm) was observed after squashing the anthers in DAPI solution (fluorochrom dying DNA). Up to

Chondriokinesis during microsporogenesis in plants [PDF]
Planta, 2017 Chondriokinesis represents a highly orchestrated process of organelle rearrangement in all dividing plant and animal cells, ensuring a proper course of karyokinesis and cytokinesis. This process plays a key role in male gametophyte formation. Chondriokinesis is a regular rearrangement of cell organelles, assuring their regular inheritance, during both ...

Morphological markers for microspore developmental stage in maize
Brazilian Archives of Biology and Technology, 2008 The use of maize in anther culture has been limited because only few genotypes presented a high androgenetic potential. Obtaining the proper stage of microspore development at culture initiation is one of the most crucial factors for success in the ...

Biologia Plantarum, 2012 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

Biologia Plantarum, 2013 The formation of cytomictic channels (CCs) during the tobacco microsporogenesis has been analyzed by microscopy and cytochemical methods. Starting from the pachytene stage, CCs were formed between microsporocytes with involvement of specific organelles ...

Plant Breeding, EarlyView.ABSTRACT The combination of polyploidy, apomixis and the formation of aneuploid and interploid hybrids makes the genus Urochloa an interesting system for investigating meiotic stability and genome behaviour in grasses. In this study, routine meiotic analysis and genomic in situ hybridization (GISH) were used to (i) evaluate meiosis in three hybrids of ...
