Water-Transport System and Its Components in Higher Plants: 5. Dynamic Model of the Water-Transport System in Transpiring Plants

Water-Transport System and Its Components in Higher Plants: 5. Dynamic Model of the... The dynamic model of aperture behavior in leaf stomata of intact transpiring plants under constant environmental conditions is considered. The model is based on the supposed existence of feed-forward relations in the water-transport system: the decrease in root resistance – reduction in the capillary tension in the leaf apoplast – enlargement of the stomatal aperture. In parallel, there is a positive feedback relation: enlargement of the stomatal aperture – enhancement of transpiration – increase in the viscous flow through the root – intensified supply of dissolved oxygen to the respiratory centers of the root symplasm – elevation of turgor and the decrease in root resistance. Under the fulfillment of nonstringent physical requirementship, this system is capable of generating auto-oscillations with a period of 20–80 min. The model describes the relationship between the frequency–amplitude characteristics of auto-oscillations and the main parameters of the water-transport system in plants. In particular, the model presents a clue to one of the most intriguing phenomenon: the moistening of the root environment increases the frequency of auto-oscillations in some cases and reduces this frequency in others. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Plant Physiology Springer Journals
