And it turns out mustard plants won’t compete with their brethren the way they will with strangers: Instead of rapidly growing roots to suck up as much water and minerals as possible, plants who sensed nearby siblings developed a shallower root system and more intertwined leaves.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.wired.com/wiredscience/2009/10/plant-siblings/"><P>“It’s possible that when kin are grown together, they may balance their nutrient uptake and not be greedy,” plant biologist Harsh Bais of the University of Delaware said in a press release.
