Research published in the journal Genetics allows scientists to overcome barrier for effective crossbreeding of tropical and temperate strains of corn Scientists may have made an "a-maize-ing" discovery that could lead to higher corn yields in the United States. In a new research report published in the March 2010 issue of the journal Genetics, scientists used tropical maize from Mexico and Thailand to discover chromosome regions responsible for detecting seasonal changes in flowering time...

Tbingen-based developmental geneticists research organ development in the plant embryo In the beginning is the fertilized egg cell. Following numerous cell divisions, it then develops into a complex organism with different organs and tissues. The largely unexplained process whereby the cells simply "know" the organs into which they should later develop is an astonishing phenomenon. Scientists from the Center for Plant Molecular Biology (ZMBP) of the University of Tbingen and the University of...

Researchers get up-close look at Pierce's Disease Like a band of detectives surveying the movement of a criminal, researchers using photographic technology have caught at least one culprit in the act. In this case, electron microscopy was used to watch a deadly bacteria breakdown cell walls in wine grape plants "“ an image that previously had not been witnessed. The study will be published in Botany. "Basically, we've been interested in determining how the bacteria moves," said Dr. B....

Nitrogen is vital for all plant life, but increasingly the planet is paying a heavy price for the escalating use of nitrogen fertilizer. Excess nitrogen from fertilizer runoff into rivers and lakes causes algal blooms that create oxygen-depleted dead zones, such as the 6,000 to 7,000 square mile zone in the Gulf of Mexico, and nitrogen in the form of nitrous oxide is a potent greenhouse gas. But new findings by Stanford researchers that reveal the inner workings of nitrogen-producing bacteria...

Power struggle between genetic master switches decides stem cell fate, growth orientation in plants The first order of business for any fledgling plant embryo is to determine which end grows the shoot and which end puts down roots. Now, researchers at the Salk Institute expose the turf wars between two groups of antagonistic genetic master switches that set up a plant's polar axis with a root on one end and a shoot on the other. "In what is arguably the most important decision for a plant,...

Ever looked carefully at the leaves on a plant and noticed their various sizes and shapes? Why are they different? What controls the size and shape of each individual leaf? Very little is known about the developmental control of leaf size and shape, and understanding the mechanisms behind this is a major issue in plant biology. A leaf's size is determined by a combination of cell number, cell size, and intercellular space. Michael Marcotrigiano from Smith College, Massachusetts, wanted to...

Flightless birds, blind cave shrimp, and other oddities suggest a "use it or lose it" tendency in evolution. In the microbial world, an unusual marine microorganism appears to have ditched several major metabolic pathways, leaving it with a remarkably reduced set of genes. This metabolic minimalist is a specialist uniquely suited to performing one very important function: taking nitrogen gas from the atmosphere and "fixing" it into a form that makes this essential nutrient available to other...

Max Planck scientists discovered how certain hormones control aspects of root branching in plants Roots are the most underestimated parts of a plant, even though they are crucial for water and nutrient uptake and consequently growth. In a world of changing water availability and an ever-increasing human population, it will therefore be crucial to understand how root development is controlled in plants. Scientists at the Max Planck Institute for Developmental Biology in Tbingen, Germany, now...

Since the time of the earliest humans, people have attempted to understand the natural environment. We have observed our surroundings and searched for explanations for natural phenomena. Yet despite our persistence over thousands of years, many basic questions remain to be answered. Although we understand core processes such as photosynthesis, we do not have a full understanding of issues such as how plants maximize their photosynthetic capacity. Specific leaf area, or SLA, plays a prominent...

Bittercress (Barbarea vulgaris), also commonly known as Herb Barbara, Rocketcress, Yellow Rocketcress, Winter Rocket, and Wound Rocket, is a European biennial herb. This plant displays a rosette of shiny, dark green leaves at the base and additional pinnately divided leaves on the stem. In the spring, yellow flowers originate in tightly packed terminal groups just above the foliage. Bittercress grows wildly as a weed in many parts of North America. The flowers can be in bloom May...

The Par Rubber Tree (Hevea brasiliensis), is a tree belonging to the family Euphorbiaceae. It is the most economically important member of the genus Hevea. It is of major economic importance because its sap-like extract (latex) can be collected and is the primary source of natural rubber. The Pará rubber tree initially grew only in the Amazon Rainforest. Now most rubber tree plantations are in southeast Asia and tropical Africa. Attempts to cultivate the tree in other areas in South...
