Maize roots have evolved to be more nitrogen efficient
University Park PA (SPX) Apr 17, 2015 - Selective breeding of maize over the last century to create hybrids with desirable shoot characteristics and increased yield may have contributed indirectly to the evolution of root systems that are more efficient in acquiring nutrients, such as nitrogen, from the soil, according to researchers. Their results suggest that future breeding efforts that directly select for positive root trait ... more
