Microsporogenesis and pollen sulcus type in Asparagales (Lilianae)
, 1997 Cladistic analysis of molecular data (plastid rbcL sequences) supports the interpretation of simultaneous microsporogenesis as an apomorphy for Asparagales (Lilianae), with a reversal in the most derived 'higher' asparagoid clade, which is entirely ...

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 ...

Oregon Wolfe barley genetic stocks – Research and teaching tools for next generation scientists
Journal of Plant Registrations, Volume 19, Issue 3, September/December 2025.Abstract The Oregon Wolfe Barley (OWB) mapping population (Reg. no. MP‐4, NSL 554937 MAP) is a resource for genetics research and instruction. The OWBs are a set of doubled haploid barley (Hordeum vulgare L.) lines developed at Oregon State University from the F1 of a cross between Dr. Robert Wolfe's dominant and recessive marker stocks.

Dynamic patterns of repeats and retrotransposons in the centromeres of Humulus lupulus L.
New Phytologist, Volume 247, Issue 6, Page 2766-2780, September 2025.Summary The centromere has a conserved function across eukaryotes; however, the associated DNA sequences exhibit remarkable diversity in both size and structure. In plants, some species possess well‐defined centromeres dominated by tandem satellite repeats and centromeric retrotransposons, while others have centromeric regions composed almost entirely ...
