Researchers discover chemical compounds that affect plant growth

..., while two of the four did not work through known auxin pathways. One of the chemicals resembled pyocyanin a product of bacterial metabolism thought to target yeast cell membranes. With chemical genomics, the team could identify valuable genetic characteristics beyond the reach of conventional mutations, ...

...aves? Researchers have discovered that the hormone auxin regulates which parts of a plant are "upper" and which are "lower". Jiri Friml, who holds two doctoral degrees, has discovered that certain proteins direct the growth hormone to where it is required. The identification of these PIN proteins is a grou...

Max Planck researchers make a breakthrough in plant stem cell research

... The first involves growth-promoting hormones like auxin and cytokinin, known already for more than half a century. The second involves genetic factors, which were discovered at the University of Tübingen, Germany about a decade ago. Here it was shown that a gene called WUSCHEL has a key influence on how m...

Pleasing plant shapes explained by new computer model

...entrations of the fundamental plant growth hormone auxin appear at regularly-spaced intervals. This creates the striking spiral patterns of seeds observed in sunflowers, daisies, and many other plants. Other patterns, such as branching at right angles observed in lilac branching, can be also be simulated ...

...es recentlyculminated in the identification of the auxin receptor by Estelle'sgroup and by Ottoline Leyser at the University of York. There had beenexhaustive, multi-year searches by laboratories across the globe forthis elusive finding. Upon being notified that Dr. Estelle had won the award, ASPB Presid...

Researchers offer clues to how leaf patterns are formed

...eral years it has been known that a hormone called auxin stimulated the formation of the veins. "It was believed that auxin would behave like man--build the streets on which man himself would travel," said Scarpella. "Howeve...
