Effects of high temperature stress on microsporogenesis and pollen production in sunflower [PDF]
, 2022 Heat stress can affect pollen production as it may interrupt the process of microsporogenesis and prevent normal pollen development. The aim of this research was to investigate whether occurence of male sterile plants in a male fertile sunflower ...

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 ...

Frontiers in Plant Science, 2021 Development of double haploids is an elusive current breeding objective in Cannabis sativa L. We have studied the whole process of anther and pollen grain formation during meiosis, microsporogenesis, and microgametogenesis and correlated the different ...

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

Microsporogenesis and anther development in Bromeliaceae
, 2005 Bromeliaceae possess several features of pollen and anther wall development that are plesiomorphic for Poales, consistent with their putatively basal or near-basal placement in this order.

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 ...

Legume Science, Volume 8, Issue 3, September 2026.ABSTRACT Rising global temperatures increasingly threaten bean production and the food security of millions of people who depend on these protein‐rich legumes. Heat stress during the reproductive stages induces pollen sterility, flower abscission, and disruptions in source–sink relationships, resulting in yield losses of 30%–40% or more when critical ...

Aggregations of organelles in meiotic cells of higher plants
Acta Societatis Botanicorum Poloniae, 2014 During early prophase I in microsporocytes and sporocytes of various plants all mitochondria and plastids aggregate in a group, where some plastids seem to undergo division. This group desintegrates by middle prophase I.

Microsporogenesis in Torreya californica. [PDF]
, 1974 Microsporangial development in angiosperms is a well documented process. In contrast, difficulties such as availability of material, prolonged development, and problems in sectioning have made information concerning microsporogenesis in gymnosperrns ...
