Answer #1

TANGLED1(TAN1) in Arabidopsis is double mutant and have a hypersensitive to a microtubule depolymerizing drug which have root growth and division plane but not have root twisting.phragmoplast formed during telophase and this phragmoplast is new wall is formed it is the first positive marker of the division site in Arabidopsis.

In maize Tan1 is important for division orientation and the mutant had misplaced cell wall. In maize tan1 is failed to mutant and failed to placed new cell wall when phragmoplast defect guidance.

Double mutant is important because it is responsible for root growth and cell division and this is more hypersensitive to deploymerizing.

Double mutant in an organism represent two mutant allel in same gene.
