Put your best root forward: How hydrotropism cannibalizes gravitropism to orient root growth towards moisture
Plant Science Research WeeklyWhile root gravitropism (growth towards gravity) has an extended history of in-depth research, less is known about root hydrotropism (growth towards water) and about how these two potentially conflicting processes interact with each other. Since soil water distribution is often heterogeneous, plant roots…
Interconnected: Hydrotropism and phototropism in Arabidopsis root growth
Plant Science Research WeeklyTropisms enable plants to shift their growth direction in response to environmental changes. The roots of Arabidopsis plants respond to gravity by growing in the direction of gravity, a phenomenon known as gravitropism, while in response to unilateral blue light they bend away, demonstrating phototropism.…
