Turgor maintenance by osmotic adjustment: 40 years of progress

Cyclic nucleotide phosphodiesterases – 40 years of progress

In this lecture I will discuss some of the relevant history of cGMP-selective and cGMP-regulated phosphodiesterases. Emphasis will be put largely on those experiments carried out in our own laboratories over the last 40 years. Short vignettes or anecdotes on the discoveries of the "cGMPstimulated" (PDE2s) and "cGMP-inhibited" (PDE3s) phosphodiesterases as well as on the original cloning of PDEs...

Breakthrough to Nursing: 40 years of progress and persistence.

Doose syndrome (myoclonic-astatic epilepsy): 40 years of progress.

Doose syndrome, otherwise traditionally known as myoclonic-astatic epilepsy, was first described as a unique epilepsy syndrome by Dr Hermann Doose in 1970. In 1989, the International League Against Epilepsy classified it formally as a symptomatic generalized epilepsy, and 20 years later it was renamed 'epilepsy with myoclonic-atonic seizures'. In this review, we discuss the components of this u...

Osmotic adjustment induced by elevated ozone: interactive effe

and elevated ozone on tissue water relations of mature clones of a fast-growing genotype of ponderosa pine (Pinus ponderosa Dougl. ex Laws.) and their half-sib seedlings. Whole seedlings and branches of mature trees were exposed to acid rain (pH 5.1 and 3.0) and ozone (ambient and twice-ambient) treatments in open-bottomed chambers. The acid rain treatment was applied to foliage weekly from Jan...

Maintenance of turgor by rapid sealing of puncture wounds in leaf epidermal cells.

When leaf epidermal cells are puncture wounded with a glass microcapillary tip, a small droplet of fluid is discharged and then evaporates, leaving a solid residue on the cell surface. For puncture wounds of about 3.5 micrometers in diameter, this process is complete within 2 to 3 seconds. A second puncture wound also exhibits a similar discharge, indicating the persistence of some turgor press...
