Biologists at Washington University in St. Louis have exposed one such interloper by characterizing the unique biochemical pathway it uses to synthesize auxin, a central hormone in plant development.

His efforts to introduce the desirable attributes of wild, perennial Glycine species into soybean plants began at the U. of I. in 1983 and followed a path that involved thousands of experiments, the development of a hormone treatment that «rescued» immature hybrid seeds from sterility, and multiple back - crosses of hybrid plants with their «recurrent parent,» Dwight.

Together with scientists from Columbia (USA), Olomouc (Czech Republic), Warsaw (Poland), Osaka (Japan) and the Freie Universitaet Berlin, the researchers at the University of Bonn have used Arabidopsis thaliana as a model plant to discover that the beet cyst nematode itself produces the plant hormone cytokinin.

A team at the University of Missouri Bond Life Sciences Center collaborated with scientists at the University of Bonn in Germany to discover genetic evidence that the parasite uses its own version of a key plant hormone and that of the plants to make root cells vulnerable to feeding.

Scientists at the University of Bonn together with an international team discovered that nematodes produce a plant hormone to stimulate the growth of specific feeding cells in the roots.

James Reid and his colleagues at the University of Tasmania in Hobart will report in the August issue of The Plant Cell that the tallness gene codes for an enzyme involved in the manufacture of the growth hormone gibberellin.

Biologists at UC San Diego have succeeded in visualizing the movement within plants of a key hormone responsible for growth and resistance to drought.

«Understanding the dynamic distribution of ABA in plants in response to environmental stimuli is of particular importance in elucidating the action of this important plant hormone,» says Julian Schroeder, a professor of biology at UC San Diego who headed the research effort.

Peter Meyer, a molecular biologist at the University of Leeds, and his colleagues identified a gene they labeled Sho (for shooting), which controls production of cytokinins, hormones that delay aging in plants.

In a paper published in the current issue of Nature Communications, Howe, a member of the Plant Research Lab at MSU, and his team describe how they were able to modify an Arabidopsis plant — a relative of mustard — by «knocking out» both a defense hormone repressor and a light receptor in the pPlant Research Lab at MSU, and his team describe how they were able to modify an Arabidopsis plant — a relative of mustard — by «knocking out» both a defense hormone repressor and a light receptor in the pplant — a relative of mustard — by «knocking out» both a defense hormone repressor and a light receptor in the plantplant.

The answer is by controlling the distribution of a plant hormone called auxin, which determines the rate at which plant cells divide and lengthen.

At the same time, the second trigger causes the plant's cells to release a specific hormone.

Additionally, the potentially negative effects on hormones and fertility warrant caution and are the reason I avoid using this plant, at least until more research is done.

But pollution also covers hundreds of chemicals which are fine or even beneficial at low levels but which if released in large quantities or in problematic circumstances cause «harm» — like phosphorus (grows your veges but also leads to toxic cyanobacterial blooms which kill cattle), nitrogen (grows crops kills many native species of plants and promotes weed growth costing farmers), copper (used as an oxygen carrier by gastropods but in high concentrations kills the life in sediments which feed fish), hormones like oestrogen (essential for regulating bodies but in high concentrations confuse reproductive cycles especially with marine life) or maybe molasses from a sugar mill (good for rum but when dumped into east coast estuaries used to cause oxygen sag in estuaries leading to massive fish kills).

One, your centuries amount to at least 650 centuries, and probably much more; this is not a starvation diet, but a hormone - free one that all plants worldwide have evolved and adapted to.

To handwave less, one refers to a document (http://www.nature.com/nchembio/journal/v5/n5/full/nchembio.165.html) that discusses the plant hormone topic (CO2 is an ethylene inhibitor) and a contrary report (though paywalled) in its abstract touches on some of the questions hot in botany today and at least tangential to what I am suggesting be considered: http://onlinelibrary.wiley.com/doi/10.1111/j.1399-3054.2011.01444.x/full

Which is the difference between CO2 levels and fertilizer levels, and again strongly argues for considering CO2 a plant hormone, or at the very least hormone - like, especially when taken with the types of anatomical and physiological changes seen in various of the studies and sources cited, that are typical of hormonal shifts, not of diet changes.
