Two clones did not sexualise. Proc R Soc Lond B— In meiotic prophase I spermatocytes of single translocation carriers, H3K27me3 was excluded from the sex body starting from the mid pachytene stage Figure 4C-Fas expected. The three groups tend to join either all together as a sister clade to all other pennates, or emerge one after another at the base of the pennates.
Nat Genet 37 : Barcoding diatoms: is there a good marker? Auxospore development and wall structure was similar in all three species and demonstrated several characters also reported from "core" araphids. Roshchin AM.
E XX oocyte at the pachytene stage. Mamm Genome 16 : We documented sexual reproduction, mating system and sex cell development in the first members of the "basal" araphid clade ever investigated. Clin Cancer Res 16 : Pyknosis of supernumerary nuclei resulting from Meiosis II is delayed in our species.
E Primary meiocyte after Meiosis I and before cytokinesis. Interspecific pair mixtures produced no auxospores, except in one instance involving the P.
No significant difference was found between the two genotypes of ovaries up to The GCNA1 gene has not been cloned and its physiological function remains unknown. Fig 5.
