Frontiers in Plant Science, 2019 Stress-induced microspore embryogenesis is a model in vitro system of cell reprogramming, totipotency acquisition, and embryo development. After induction, responsive microspores abandon their developmental program to follow an embryogenic pathway ...

Acta Societatis Botanicorum Poloniae, 2015 The development of microspores and pollen grains lasts in Tradescantia bracteata in vivo from the tetrad stage to pollen shedding about 14 days. This including 7 days of the microspore life cycle. In stamens excised and placed on a medium the microspores

Cytological characterization and allelism testing of anther developmental mutants identified in a screen of maize male sterile lines. [PDF]
, 2013 Proper regulation of anther differentiation is crucial for producing functional pollen, and defects in or absence of any anther cell type result in male sterility.

Frontiers in Plant Science, 2019 Microspore embryogenesis is a manifestation of plant cell totipotency whereby new cell walls are formed as a consequence of the embryogenic switch. In particular, the callose-rich subintinal layer created immediately upon induction of embryogenesis was ...

Production of embryos from microspore cultures of Portuguese tronchuda cabbage landraces [PDF]
, 1996 Twelve accessions of tronchuda cabbage landraces were tested for their ability to produce embryos through microspore culture in NLN-13 medium. A sample from all the isolations was stained with DAPI for determination of microspore developmental stage. The

The Plant Journal, 2019 Sexual reproduction in flowering plants relies on the production of haploid gametophytes that consist of germline and supporting cells. During male gametophyte development, the asymmetric mitotic division of an undetermined unicellular microspore ...

Obtaining calli and regenerated plants in anther cultures of pea
Czech Journal of Genetics and Plant Breeding, 2014 Pea (Pisum sativum L.) is a species for which there is no efficient method for the recovery of haploid plants yet. This research investigated the influence of various genotypes, nutrient media, and stress treatments on callus formation, embryogenesis and

Chromatin differentiations in microspores
Experientia, 1971 2 p.-1 fig. En núcleos de microsporas deAllium cepa se describen estructuras de 1 µm de diámetro, de baja densidad y estrechamente relacionadas con varias masas de cromatina, las que se equiparan con los denominados «micropuff» recientemente descritos.
