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.”

How to Do Stand Counts in Corn

Video: How to Do Stand Counts in Corn


Stand counts are one of the most important early-season checks you can do in a corn field. In this video we walk you through exactly how to do them, what to look for, and when to worry. We cover the two-tool method, the two-leaf-stage rule, replanting decisions, herbicide residual considerations, and velvet leaf identification. Planted April 11th in cold conditions, stand counts came back solid at around 30,000 across the field.
