1999 journal article

Microtubule and actin filament organization during acentral divisions in potato suspension culture cells

PROTOPLASMA, 207(3-4), 158–168.

By: D. Collings* & M. Emons

author keywords: filamentous actin; cytoskeleton; microtubules; phragmoplast; phragmosome; Solanum tuberosum; suspension culture
TL;DR: It is hypothesize that it is the uneven fusion of the expanding cell plates with the parent plasma membrane, and the accompanying depolymerization of those parts of the phragmoplasts, that gives the incomplete phragMoplasts observed. (via Semantic Scholar)

1998 journal article

Plasma membrane-associated actin in bright yellow 2 tobacco cells - Evidence for interaction with microtubules

PLANT PHYSIOLOGY, 118(3), 917–928.

By: D. Collings n, T. Asada*, N. Allen n & H. Shibaoka*

TL;DR: The experiments suggest that the organization of the cortical actin arrays may be dependent on the localization and Organization of the microtubules, and this work has identified several factors, including the use of a mildly acidic actin stabilization buffer and the inclusion of glutaraldehyde in the fixative, that allow immunofluorescent visualization.
