Cytoplasmic pH Regulation in Acer pseudoplatanus Cells: II. Possible Mechanisms Involved in pH Regulation during Acid-Load.

abstract：:Root size and architecture are important crop plant traits, as they determine access to water and soil nutrients. The plant hormone cytokinin is a negative regulator of root growth and branching. Here, we generated transgenic barley (Hordeum vulgare) plants with an enlarged root system by enhancing cytokinin degradati...
