Possible explanation for more efficient maize growth

Maize has a significantly higher productivity rate compared with many other crops. The particular leaf anatomy and special form of photosynthesis (referred to as C4) developed during its evolution allow maize to grow considerably ...

Modern microbes provide window into ancient ocean
