The survival of terrestrial plants depends upon the capacity of roots to obtain water and nutrients from the soil. Directed growth of roots in relation to a gradient in moisture is called hydrotropism and begins in the root cap with the sensing of the moisture gradient. Even though the lack of sufficient water is the single-most important factor affecting world agriculture, there are surprisingly few studies on hydrotropism. Recent genetic analysis of hydrotropism in Arabidopsis has provided… CONTINUE READING
