Twisted pollen tubes induce infertility in plants with multiple sets of chromosomes
Most mammals and humans have a double set of chromosomes—and as a rule, plants do, too: One set comes from the father, the other from the mother. Such organisms are called diploids. However, sometimes the number of chromosome sets doubles from one.....»»

Satellite images of plants" fluorescence can predict crop yields
Cornell researchers and collaborators have developed a new framework that allows scientists to predict crop yield without the need for enormous amounts of high-quality data—which is often scarce in developing countries, especially those facing heig.....»»
Study: World War II plant construction expanded high-wage manufacturing jobs, benefiting residents and their children
In a new study, researchers have examined the long-term effects of government-led construction of manufacturing plants during World War II on the regions where they were built and on residents. The study found that wartime construction had large and.....»»
Researchers find that calcium can protect potato plants from bacterial wilt
Scientists have discovered that calcium plays a significant role in enhancing the resistance of potato plants to bacterial wilt. This disease causes worldwide losses of potatoes costing $19 billion per year. The findings open up new avenues for integ.....»»
