2g-i) is associated with division of the single plastid, which serves as an MTOC (P-MTOC).
Immediately following cytokinesis an MTOC occurs between the nucleus and the adjacent distal wall in each young spore.
This repositioning of MTOCs that generate opposing microtubules in the interzone also occurs after mitosis in higher plants (Brown & Lemmon, 2007).
All three types of MTOCs (POs, P-MTOCs, and NE-MTOCs) have been discovered in meiosis of bryophytes (Brown & Lemmon, 2007; Brown et al.
Most MTOC teams come from large towns, with multiple teams in each age group.
Microtubules emanate from the four plastid MTOCs to re-establish a tetrahedral QMS (Fig.
Tips of the two plastids are at the vertices of a tetrahedron and serve as the MTOCs that nucleate microtubules of the QMS, but the plastids do not actually complete division until metaphase I (Busby & Gunning, 1988a, b).
In most cases, there is no evidence of a discrete structure associated with the poles, but in the bryopsid moss Rhynchostegium serrulatum, spindle microtubules appear to be focused at electron dense clusters (Brown and Lemmon, 1982a) that are thought to constitute the MTOCs.
The leagues that participate in MTOC include Berkshire, Boston Area Youth Soccer, Coastal, Essex, Middlesex, Midland Area Youth Soccer, Nashoba, Pioneer Valley, South Coast and South Shore.
spermatid, the early MTOC is subtended by several folds of nucellar
The plastids serve as MTOCs that nucleate four opposing systems of microtubules early in meiotic prophase.
Self-organization of MTOCs replaces centrosome function during acentrosomal spindle assembly in live mouse oocytes.
