The plasmalemma is both a bridge and a barrier between the cytoplasm and the outside world. It is a dynamic interface that perceives and transmits information concerning changes in the environment to the nucleus to modify gene expression. In plants, ascorbate is an essential part of this dialogue. The concentration and ratio of reduced to oxidized ascorbate in the apoplast, for example, possibly modulates cell division and growth. The leaf apoplast contains millimolar amounts of ascorbate that… CONTINUE READING
