Abscisic acid is a negative regulator of root gravitropism in Arabidopsis thaliana.

Biochemical and biophysical research communications - 23 Jan 2009

Han Woong, Rong Honglin, Zhang Hanma, Wang Myeong-Hyeon

Abstract excerpt

The plant hormone abscisic acid (ABA) plays a role in root gravitropism and has led to an intense debate over whether ABA acts similar to auxin by translating the gravitational signal into directional root growth. While tremendous advances have been made in the past two decades in establishing the role of auxin in root gravitropism, little progress has been made in characterizing the role of ABA in this response....
