National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Role of Sucrose in Emerging Mechanisms of Stomatal Aperture Regulation.

DE2005829934

Publication Date	2005
Personal Author	Outlaw, W. H.
Page Count	16
Abstract	The research focused on the second of 2 hypotheses that were proposed for testing that transpiration rate determines the extent to which suc accumulates in the GC wall providing a mechanism for regulating stomatal aperture size. The hypothesis received strong support because the suc content of the GC apoplast fell 7-fold on lowering of the WD. Progress in other related areas (SUC uptake mechanism, physiological effect of external SUC, and especially the kinetics of ABA accumulation in the guard-cell wall) has also been made.
