Developing Adventitious Root Meristems Induced by Layering for Plant Chromosome Preparation.

ABSTRACT: Chromosome numbers and morphology are important characteristics of a species and its evolution. Root tips are the most commonly used tissue as a source of actively dividing cells for chromosome visualization in plants. Previously, rapidly growing root tips were collected from germinating kernels or from seedlings growing in pots or fields. However, the use of adventitious roots (ARs) derived from aerial tissue as meristems for chromosome visualization has always been overlooked. Here, we successfully induced ARs in 12 materials that were investigated, with the exception of Sorghum nitidum. Using ARs meristem we obtained high-quality chromosome spreads for Morus alba, Broussonetia papyrifera, Lolium multiflorum, Sorghum sudanense, S. propinquum</
