Vernalization
fixity — the behavior of fossil organisms will be similar to the behavior of their extant descendants at the generic level — my wife and I re-constructed the type of Tertiary forest that existed in Hispaniola based on plants and animals in Dominican amber. We concluded that the amber forest in Hispaniola was similar to today’s tropical moist forest, but was much more diverse and contained a num...
متن کاملVernalization in cereals
How vernalization - exposure to a period of cold - induces flowering in Arabidopsis has been intensively investigated at the genetic and moleular levels. Recent papers, including one in BMC Plant Biology, shed light on changes in gene regulation that occur on vernalization in cereals.

متن کاملPeas and Primroses
Remember the monk and the peas? The story introduced school children to genetics long before the human genome made the evening news. The Augustinian monk Gregor Mendel conducted hundreds of experiments on the edible pea, crossing peas that were smooth or wrinkled, peas that grew tall or short, peas that had white or violet flowers. He found that the results of these crosses were predictable, an...
متن کاملVernalization response of wild chickpea
• Response to low temperature during early growth in cultivated chickpea (Cicer arietinum) and its wild progenitor C. reticulatum was investigated to clarify the evolutionary processes under domestication in this crop. • Parental lines and their F2 and F3 progeny were exposed to cold treatment (4°C) for 30°d after seed imbibition and compared with controls. • Cold treatment caused a 19-d advanc...
