Abstract:Background: Maize (Zea mays) ear length, which is an important yield component, exhibits strong heterosis. Understanding the potential molecular mechanisms of ear-length heterosis is critical for efficient yield-related breeding.Results: Here, a joint netted pattern, including six parent-hybrid triplets, was designed on the basis of two maize lines having long (T121 line) and short (T126 line) ears. Global transcriptional profiling of the young ears (containing meristem) was performed. Multiple comparative ana… Show more
