From: A high-throughput transient gene expression system for switchgrass (Panicum virgatum L.) seedlings
Microtitre plate of seedlings inoculated with Agrobacterium , treated by sonication, needle wounding or mixing by vortex with carborundum and stained for β-glucuronidase (GUS)Plus activity. (a) Control (sonicated) switchgrass seedlings; (b) sonicated seedlings that were needle inoculated; (c) sonicated seedlings that were mixed by vortex with carborundum. All seedlings were assayed for GUSPlus activity.
