Regulation of soybean seed germination through ethylene production in response to reactive oxygen species.

abstract：BACKGROUND AND AIMS:Theory for optimal allocation of foliar nitrogen (ONA) predicts that both nitrogen concentration and photosynthetic capacity will scale linearly with gradients of insolation within plant canopies. ONA is expected to allow plants to efficiently use both light and nitrogen. However, empirical data gen...
