Behind them are the completed genome sequences of rice1 and the model mustard plant Arabidopsis thaliana.2 Now, armed with insights gained from both plant and animal sequencing projects, plant biologists must decide how to proceed with future sequencing, proteomics, and functional genomics endeavors--and how to allot precious basic research dollars while, at the same time, keeping

FEATURERestoring Natural Capital Courtesy of M. Powell Working for Water in South Africa The sides of the Baviaanskloof ("Baboon Canyon") in South Africa's Eastern Cape Province range from very steep to vertical. Halfway up a 45-degree slope, under the supervision of spirited 19-year-old Abbey-gail Lukas, 10 men and women are planting thick cuttings of a plant locally known as Spekboom (Portulacaria afra) in circles three meters apart.
Research On Global Climate Heats Up

Until six months ago or so, ecologist H. Ronald Pulliam never bothered with fax machines. Now his work depends on them. Every day he and 20 colleagues use the machines to iron out the details of a multimillion-dollar, multidisciplinary, multi-university proposal to study how plants interact with the atmosphere. But fax machines aren't the only things that have changed the way Pulliam, director of the Institute on Ecology at the University of Georgia, carries out his work on global change. Indeed

With genome sequences arriving almost as regularly as the morning paper, the public's attention is focused on genes--new genes to protect crops against pests; rogue genes that make bacteria resistant to antibiotics; faulty genes that, if fixed, could cure diseases such as muscular dystrophy. What many people don't realize is that genes account for only part of an organism's DNA, and in many c

Courtesy National Science Foundation Headlines on the morning of December 14, 2000, trumpeted the end of a presidential election that promised to go on forever. But if California Institute of Technology molecular biologist Elliot Meyerowitz had his way, the front page would have read differently: "Plant Genome Sequenced" at the top, then, lower down, "Election Decided - See Page 2." In a tour de force that capped a year of genome blockbusters, European, Japanese, and American scientists complet
