Whatever does not kill a plant may actually make it stronger. After being partially eaten by grazing animals, for example, some plants grow bigger and faster and reproduce more successfully than they otherwise would. In a new study, researchers report that one secret to these plants' post-traumatic triumph lies in their ability to duplicate their chromosomes "“ again and again "“ without undergoing cell division. While this process, called "endoreduplication," is not new to...

Fast-food restaurants can supersize French fries and drinks, but Mother Nature has found a way to supersize a type of apple. Peter Hirst, a Purdue University associate professor of horticulture, found that an anomaly in some Gala apple trees causes some apples to grow much larger than others because cells aren't splitting. The findings, reported in the current issue of the Journal of Experimental Botany, showed that the new variety, called Grand Gala, is about 38 percent heavier and has a...

Caltech-led team provides evidence of key roles for cell-cycle length and chromosome duplication without division The sepals of the plant Arabidopsis thaliana"”commonly known as the mouse-eared cress"”are characterized by an outer layer of cells that vary widely in their sizes, and are distributed in equally varied patterns and proportions. Scientists have long wondered how the plant regulates cell division to create these patterns"”in other words, how it decides which and...

Study on maize domestication may help improve crop yields Understanding the evolution and domestication of maize has been a holy grail for many researchers. As one of the most important crops worldwide and as a crop that appears very different from its wild relatives as a result of domestication, understanding exactly how maize has evolved has many practical benefits and may help to improve crop yields. In the October issue of the American Journal of Botany...
