With reference to the secondary axis (approximately defined at this stage by the 'dorsal' 3D macromere) the basal cells 1m12 are positioned on dorsal, ventral, and lateral radii of the head rudiment.
Preactinotrocha (approximately, 55 63 hps).: At this stage, the proctodaeum appears but the larva is still lecithotrophic.
RNA-Seq data were collected from maturing gelatinous endosperm (coconut approximately 5 months old, embryo invisible at this stage), nearly mature embryo (coconut at approximately 8 months old), and young leaf (seedling at approximately 8 months old).
We found that approximately half of the embryos at this stage appeared normal (Figure 2B, left panel), while the other half was severely deteriorated (Figure 2B, right panel), suggesting that these embryos have been dead by the time of dissection.
At this stage, approximately 60%% of cells in flasks to which spores had been added exhibited signs of infection.
At this stage, approximately 200 juveniles were randomly collected from the hapas and transferred to the challenge test facility where they were introduced into a 4 t concrete cement tank.
At this stage, approximately 1000 Buchnera aphidicola bacteria are transmitted from maternal bacteriocytes to a single viviparous embryo, and they increase in number by 120 fold during the remaining embryonic development [ 1, 13, 15- 17].
Active migration of X. laevis germ cells in the endoderm starts approximately at developmental stage 24 (Blaser et al., 2005).
Cells at this stage are approximately three-times longer than cells at mid-log phase.
Pictures to assess the fitness of double mutants were taken at this stage every approximately 12 h.
