  • Scientists study microspores to understand their role in plant reproduction.
  • nucleate microspores
  • microspore culture

Examples

  • In the latter case, two demonstrably rare events must occur simultaneously -- both a polyploid microspore and a polyploid megaspore must be formed to produce the egg and sperm that are necessary to initiate a new sporophyte (Figure 4).

  • The plant produces microspores that eventually develop into male gametophytes.

  • Microspores, on the other hand, have been largely neglected in taxonomic schemes until recently.

  • The floral buds ranging from 13-15 mm in size have a higher percentage of uninucleate microspores compared with other sizes.

  • Haploids can be regenerated from anther or microspore explants, and the genome can be doubled using genome doubling agents like colchicine.

    Academic text (2015)
  • In the anthers, male microspores undergo an initial asymmetric mitotic division, and the smaller generative cell migrates into the larger vegetative cell.

  • I. iapygia has probably evolved gradually as a result of spatial isolation and low genetic exchange with congeners due to the low dispersal ability of macro- and microspores.

  • Slides were observed under the Nikon Optiphot Fluorescence Microscope at 40x for the uninucleate stage of the microspores (Summers et al., 1992).

Morphology

microspore = spore (semi-transparent) = micro + spore

The word is transparently built from the prefix micro- 'small' and spore, but the overall meaning is a specialized biological term.

Etymology

Microspore comes from micro- meaning 'small' and spore meaning 'a seed-like cell that can grow into a new plant stage'. So a microspore is the small spore that usually develops into the pollen or the male part of some plants.
