Early diversification of seeds and seed-like structures

Early diversification of seeds and seed-like structures

The seed habit is one of the most important evolutionary acquisition in plant evolution. It allowed colonisation of new ecological niches, leading to a level of diversification never observed before. The seed habit involves occurrence of a single functional megaspore within an indehiscent megasporan...
