At the migratory slug stage the tip-organizer is necessary for locomotion of the organism and it contains the light sensitive areas that direct slug phototaxis [ 40].
Africa is now at this stage – the development tipping point.
The sample was placed on a plane stage, under the tip of a water-dispensing disposable blunt-end stainless steel needle with an outer diameter of 0.5 mm.
But we'll let you take a look for yourself (hat tip to The Back Stage for the tip).
Genes activated at mid-gastrula stage at the tip of the archenteron and endure throughout gastrulation include foxc and eya.
The electrode gap was determined at the end of the experiment by using the micrometer readings on the Z stage of the tip mount, with the tip touching the ITO as a reference point.
At the later stage, when the tip including all the leaf primordia was completely necrotic, separation of the cells in pith and cortex of the stem at the abscission site had occurred.
At this stage, the dedifferentiated tips of the radial nerve stumps form thin tubular outgrowths penetrating into the connective tissue that fills the wound gap.
When seedlings were at 3-leaf stage, the root tips were cut to produce wound and then cultivated in a cultivation cabinet.
