New Techniques Enhance Analysis of Early Leaf and Root Growth in Maize

Two recent papers from maize genetics labs in the Division of Biological Sciences introduce novel methods for studying the anatomy and cellular traits of maize tissues at early developmental stages.

In the Journal of Visualized Experiments, the McSteen Lab presents two methods that overcome the challenge of studying early maize leaf development, where the leaf primordia are “deeply ensheathed and rolled within the leaf whorl.” These methods make it possible for researchers to exploit fluorescence and confocal imaging to visualize anatomy and cellular features of developing leaves. Alumnus Dr. Janlo Robil (Ph.D., 2022) is first-author of the paper.

In a separate publication in Bio-protocol, the Braun Lab describes a modified plate-growth procedure for maize. This method allows researchers to track root growth over time, starting as early as two days after germination. This technique builds upon a procedure commonly used in Arabidopsis research and adapts it to the specific needs of maize. According to the authors, “The procedure can grow seedlings under a variety of conditions and treatments in a sterile environment, allowing researchers to investigate numerous effects in the embryonic root and shoot systems of maize and other cereal crops.”

Developing disease resistance in new wheat varieties

Video: Developing disease resistance in new wheat varieties


Dr. Colin Hiebert, research scientist with Agriculture and Agri-Food Canada – Morden, is focused on developing new tools that wheat breeders can use to improve, diversify and strengthen disease resistance in new wheat varieties. This includes new genomic tools that address resistance to five diseases including: Fusarium head blight, leaf rust, stripe rust, stem rust and common bunt.

Learn more about how research conducted at AAFC-Morden will impact wheat variety development, production and profitability for the future. This research is part of the Canadian National Wheat Cluster and funding is provided through the Sustainable Canadian Agricultural Partnership, Agriculture and Agri-Food Canada, Alberta Grains, Sask Wheat, Manitoba Crop Alliance, Western Grains Research Foundation and Canadian Field Crop Research Alliance.
