A ragged mass of desiccated roots clings to one rounded side; the other side may have a slight indentation and, occasionally, the nub of an emerging sprout.
Displaying a gene expression profile distinct from that of the stalk cell, the tip cell is the spearhead selected to lead the emerging sprout, and it is followed by the endothelial stalk cells (Phng and Gerhardt, 2009).
For bare root seedlings, nursery bed soil needs to be loose so that seednuts laid horizontally, at no more than half their depth, can be tilted slightly forward towards the eye end so that the water in the nut moistens the embryo and the thickest part of the husk gives support to the emerging sprout.
One-cm tuber tissue pieces were collected at 0 cm ('edge' tissue containing skin cells) or 4.5 cm ('flesh' tissue) down from the apex, beneath the emerging apical sprouts (Fig. 3a).
Aortic rings, isolated from wild-type, Rpl29-heterozygous and Rpl29-null embryos at embryonic day 18.5 (E18.5), were treated with VEGF or PBS and the number of emerging microvessel sprouts counted after 5 days in three-dimensional culture.
Wait for two weeks until you can see sprouts emerging from the seeds.
Put your seeds in a plastic zip-lock bag with a loose, dampened growth medium (for example, vermiculite) and take them out in the spring when you see sprouts emerging.
After 5 days, sprouts with emerging roots and shoots but with the first leaf still folded were subjected to hypoxia treatment by placing them in airtight Erlenmeyer flasks filled with 300 mL of distilled water, through which high-purity N2 gas was flushed to reduce and maintain the oxygen concentration at about 0.5 mg L−1 (Ellis and Setter, 1999).
Since ISV sprouts emerge bilaterally from the DA, we analyzed one side of sprouting ISVs.
Moreover, browse impacts on sprouts emerged before impacts were detected on seedling abundance, height, or biomass.
During regeneration of injured peripheral nerves, local conditions may influence how regenerative axon sprouts emerge from parent axons.
