In a new study, the Papaver rhoeas (poppy family) self-incompatibility system has been transferred into Arabidopsis thaliana, a distantly related plant with a very different floral structure. The simple poppy self-incompatibility system may finally make it possible to introduce this potentially valuable trait into any plant.

IN the January, 1872, number of the Indian Medical Gazette is an article on "Opium," written by Dr. Moore, wherein that gentleman states that, from personal observation, he arrives at the conclusion, " that opium-eating when moderately indulged in?as it generally is?produces no decided or even appreciable ill effect." Moreover, that the use of opium, under certain circumstances, is beneficial. ...

That ease should be procured by the juice of a poppy! that the wonderful mind should be influenced by a cause so apparently insignificant I The great John Hunter exclaimed, Thank God for opium! and it is an undoubted blessing that the Creator should have permitted such an antidote to the sufferings ot mank...

We have previously demonstrated that increases in cytosolic free Ca2+ are triggered by the self-incompatibility (SI) response in incompatible Papaver rhoeas (the field poppy) pollen. However, one key question that has not been answered is whether extracellular Ca2+ may be involved. To address this question, we have used an ion-selective vibrating probe to measure changes in extracellular Ca2+ f...
