SUMMARY:How does your garden grow: the complex nature of plant growth 
 below ground\, Chaos & Complex Systems Seminar\, Simon Gilroy\, Botany
DESCRIPTION:Nutrient and water uptake by the root system is a critical
  component of plant productivity and plant root systems have evolved t
 o be extremely effective at exploring and exploiting the soil. However
 \, we still have a remarkably poor understanding of the dynamics of th
 e development of the root systems and how\, at a cellular and molecula
 r level\, control systems operate to precisely regulate the direction 
 and extent of growth. Similarly\, we are now only just beginning to ap
 preciate how these features of growth are integrated into the role of 
 the root system in nutrient and water uptake. Our research has reveale
 d a highly dynamic and complex regulatory network involving rapid\, fl
 uctuating patterns of acidity\, chemical oxidation and classic signali
 ng molecules such as the calcium ion that are integrated to modulate r
 oot growth. I will discuss how these patterns play out with time cours
 es of a few seconds\, bringing the regulation of plant growth into the
  temporal realm we usually associate with animal responses.
