terms

Mechanism involves weakening of the cell walls of the surrounding seed tissues,
especially at the micropylar region

Pectin methylesterase (PME) is a cell wall hydrolase involved in mediating
weakening of the cell walls of the megagametophyte of yellow-cedar

Acidic environment (due to IAA (auxin)) of cell wall ph7 activates Expansin which loosens cell wall by breaking down hemicellulose

In Arabidopsis:
Efflux carriers
PIN gene-family of eight
Influx carriers
AUX gene-family of four
