Nitrogen-induced changes in the growth and metabolism of developing maize kernels grown in vitro.

abstract：:We previously reported (A Reinero, RN Beachy 1986 Plant Mol Biol 6:291-301) that coat protein (CP) of tobacco mosaic virus (TMV) accumulates in chloroplasts of systemically infected leaves. To determine the significance of such interaction we examined electron transport rates in chloroplasts containing different level...

About 30% of arable land is considered Fe deficient because of calcareous soil that renders Fe unavailable to plants. Under Fe-deficient conditions, Arabidopsis (Ar...
