As a result we may postulate a different set of genes activating under drought stress in these different stages of plant growth as the plant moves from vegetative to reproductive phases.
"It offers lots of nutrients early in the season, then a water deficit, which tells the vines, 'I need to ripen and get out of here,' moving from a vegetative to a fruit cycle".
But it is also relevant to indicate that the agave handlers are moving seeds and vegetative propagules from forest to forest, from forests to plantations and among plantations themselves, thus promoting gene flow among populations.
At a fundamental level, unlike crop agriculture, livestock producers can respond to the spatial heterogeneity of vegetative production by moving livestock to where it has rained.
The move towards vegetative propagation resulted in dramatic reduction of juvenility (Akinnifesi et al. 2004).
According to Zohary and Spiegel-Roy (1975), the revolutionary move towards vegetative propagation brought about a breakdown of natural pollination systems.
In the first reported use of the technique, a 23-year old patient, who had been diagnosed as vegetative for one year, imagined playing tennis and moving from room to room in her house when instructed to do so [ 5].
Patients who do show signs of awareness those who are able to obey a command to blink or track a moving object with their eyes, for example—are by definition not vegetative and are spared this fate.
A study in Science from 2006 found that a vegetative patient who was asked to imagine "playing tennis or moving around her home" showed much more brain activity than expected.
