Abstract

Comparative transcriptome profiling of inbred maize lines demonstrates remarkable similarities and a large number of antisense transcripts.

Highlights

  • There are thousands of maize lines with distinctive normal as well as mutant phenotypes

  • Biological materials and study design The W23, ND101, and an A619 derivative are Corn Belt Dent varieties, a classification based on origin and seed morpholhttp://genomebiology.com/2006/7/3/r22

  • Despite the phenotypic and genotypic diversity of maize, transcriptome profiling indicates that the three lines tested share remarkable similarities in gene expression patterns across diverse tissue types, especially in both reproductive tissues

Summary

Introduction

There are thousands of maize lines with distinctive normal as well as mutant phenotypes. The diversity of extant lines reflects both the ease of crossing corn (Zea mays L.) and the long life of seeds. These lines are derived from hundreds of landraces collected in US farmers' fields and from native. Americans beginning in the early 20th century Lineage records track these materials, the crosses among them, and the inbred lines derived over the past century [1,2]. It is of great interest to quantify line-specific aspects of gene expression that are the underlying basis for phenotypic variation among inbreds and hybrids and to determine the characteristic patterns of gene expression in specific organs in multiple wild-type lines before examining the impact of mutations on the transcriptome of developing organs
