Over‐expression of tricarboxylic acid metabolism genes in forage crops Neonotonia wightii and Brachiaria brizantha leads to ectropic root development

摘要：

Acid soils comprise approximately half of the total agriculturally viable surface of the planet and its main limitation is caused by aluminum toxicity that leads to impaired root growth,thus decreasing water and nutrient absorption by the plants. Recently,it has been demonstrated that anion secretion by the roots is an important mechanism of Al tolerance.In the present work,it has been stably introduced and over-expressed genes coding for a citrate and malate synthase genes in perennial soybean (N.wightii) and palisadegrass (B.briz antha),respectively.
