Maize microsporogenesis

Genome, 1989
The use of maize (Zea mays L.) pollen for basic scientific research has been well documented, but the progression of clear cytological features of maize microsporogenesis has not been fully documented. This study was undertaken to identify cytologically the different developmental stages of maize pollen and to correlate them with morphological ...

Photoinduced Microsporogenesis in Rice

Botanical Gazette, 1974
Fourteen-day-old plants of a photosensitive winter variety of rice, cv. BAM-3, were subjected to photoinductive cycles of 8-hr light and 16-hr darkness for 1, 2, 3, 4, 5 weeks, or until anthesis. Short-day treatment for 1 and 2 weeks caused vacuolation in the cytoplasm of a few of the sporocytes.

Molecular control of microsporogenesis in Arabidopsis

Current Opinion in Plant Biology, 2011
Microsporogenesis is essential for male fertility and requires both the formation of somatic and reproductive cells in the anther and meiotic segregation of homologous chromosomes. Molecular genetic studies have uncovered signaling molecules and transcription factors that play crucial roles in determining the anther cell types and in controlling gene ...

Cytomixis in the cereal (Gramineae) microsporogenesis

Protoplasma, 2015
The specific features in behavior of the nuclei and chromatin migrating through cytomictic channels as well as in formation of micronuclei in the cereal microsporogenesis have been studied. Immunofluorescence microscopy has allowed for demonstration that the tubulin cytoskeleton does not play a significant role in the intercellular migration of nuclei.

MICROSPOROGENESIS IN JATROPHA CURCAS L.

Acta Horticulturae, 2012
Jatropha curcas L. is an important oil crop for biofuel production. As such, the yield is commercially important and breeding programmes are focused to select and propagate high yielding individuals. Haploid plants are very useful in these programmes to produce true homozygotes in a short period of time.

Phenological measurements of microsporogenesis in trees

Tree Physiology, 1995
The value of two heat sum methods, one linear (degree days > 5 degrees C) and the other curvilinear (period units), were assessed together with calendar days as predictors of the duration of microsporogenesis in seven natural stands of Norway spruce (Picea abies (L.) Karst.) and eleven natural stands of Scots pine (Pinus sylvestris L ...
