The root is the interface between plant and the soil. This
means that the root is the organ that is directly affected by human
managements (e.g., tillage and fertilization). The formation
of well-developed root system is important for crops to alleviate the
soil environmental stress such as water stress, nutrient deficiency,
high (or low) pH and so on. Thus, I study the factors determining the
root vertical distribution and analyze how the morphological and physiological
properties of individual roots are integrated to the structure and function
of the whole root system.
I also study the anatomy of roots, in particular, cell wall structure
in the cortex (including the exodermis and endodermis) in relation to
their eco-physiological functions.
