Cytoplasniic differentiation during microsporogenesis in higher plants
Acta Societatis Botanicorum Poloniae, 2014 Conspicuous cytoplasmic dedifferentiation in the pollen mother cells takes place early in the meiotic prophase of many plants. This event involves the removal of much of the cytoplasmic RNA. and the differentiation of both plastids and mitochondria to approaching the sole expression of their genomes. Much of the RNA removed from the cytoplasm passes to

High temperature injury and auxin biosynthesis in microsporogenesis
Frontiers in Plant Science, 2013 Plant reproductive development is more sensitive than vegetative growth to many environmental stresses. High temperature (HT) injury is becoming an increasingly serious problem due to recent global warming. In wheat, barley, and other crops, the early phase of anther development is most susceptible to HT.

Male gametogenesis in flowering plants
Frontiers in Sustainable Food SystemsThe life cycles of plants are characterized by significant alternations between the diploid sporophytic and the haploid gametophytic generations. Meiosis and fertilization are the prerequisites for achieving the alternation of generations.

Cytogenics, morphology and viability of Borreria spinosa (Rubiaceae) pollen grains
Cuadernos de investigación UNEDIntroduction: Borreria spinosa is a herbaceous plant considered a weed in agricultural crops, although it also has potential in apiculture. Despite its agronomic importance, its cytogenetic and palynological traits are poorly known. Objective: To do the
