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...

Scientists on the Norwich Research Park, working with colleagues in China, have developed new techniques that will aid the application of genomics to breeding the improved varieties of crop needed to ensure food security in the future. By dissecting the complicated genome of oilseed rape they have been able to produce maps of the genome that are needed for predictive breeding. Traditional breeding involves crossing two varieties and selecting the best performing among the progeny. Predictive...

Many plants use similar genes to build their cell walls Plants have neither supportive bone tissue nor muscles, and yet they can form rigid structures like stalks and even tree trunks. This is due to the fact that plant cells are enveloped by a stable cell wall. The main component of the plant cell wall is cellulose, which represents almost 50 percent of the total cell wall material and, at one billion tonnes per year, is the most frequently produced macromolecule in nature. Very little is...

According to a new study, male mice that were exposed as babies to Bisphenol A (BPA) acted more like females and were seen as less desirable mates. The study said the findings could have implications for how BPA, which is a common chemical in canned foods and plastic containers, may affect human development and behavior. "The BPA-exposed deer mice in our study look normal; there is nothing obviously wrong with them. Yet, they are clearly different," lead author Cheryl Rosenfeld at the...

Sharing about 95 percent of their genes with humans, mice are recognized around the world as the leading experimental model for studying human biology and disease. But, says Jackson Laboratory Professor Gary Churchill, Ph.D., researchers can learn even more "now that we really know what a laboratory mouse is, genetically speaking." Thanks to an in-depth analysis by a team led by Fernando Pardo-Manuel de Villena, PhD, in the University of North Carolina, Chapel Hill Department of Genetics and...

Rice originated in China, a team of genome researchers has concluded in a study tracing back thousands of years of evolutionary history through large-scale gene re-sequencing. Their findings, which appear in the latest issue of the Proceedings of the National Academy of Sciences (PNAS), indicate that domesticated rice may have first appeared as far back as approximately 9,000 years ago in the Yangtze Valley of China. Previous research suggested domesticated rice may have two points of...

With seedlings and shoots still poking their leafy tops out of the soil, it's hard to read the newly published research of Brown University biologist Alison DeLong without musing that it provides a deeper understanding of what puts the spring in spring. DeLong's paper, published in advance online April 21 in PLoS Genetics, reveals fertile new insights into the intricate network of proteins that controls plant growth and development, particularly at the seedling stage. But the research also...

Despite being closely related to the lyre-leaved rock cress, the thale cress has a considerably smaller genome It would appear reasonable to assume that two closely related plant species would have similar genetic blueprints. However, scientists from the Max Planck Institute for Developmental Biology in Tbingen, working in cooperation with an international research team have now decoded, for the first time, the entire genome of the lyre-leaved rock cress (Arabidopsis lyrata), a close...

Ossabaw Island Hog
2014-09-02 09:37:37

The Ossabaw Island hog, also known as the Ossabaw Island, is a breed of pig that developed from a herd of feral pigs on Ossabaw Island, Georgia in the United States. The original population of hogs was brought to the island by the Spaniards during the sixteenth century for the purpose of later consumption, which was a typical practice during Spanish exploration at that time. The pigs became isolated on the island for hundreds of years and had little interaction with domestic pig breeds or...

Western Clawed Frog, Xenopus, tropicalis
2014-08-21 10:26:56

The western clawed frog is also known as the tropical clawed frog and is found widespread in the regions of Nigeria, Liberia, Gambia, Guinea, Cameroon, the Ivory coast, and surrounding areas. The habitat for the western clawed frog is moist areas in tropical and subtropical rivers, lakes, marshes, swamps, agricultural ponds, and canals. The body color of the western clawed frog is light to dark brown and covered with grey and black spots. The eyes protrude up from the head. Tubercles...

Fraser’s Clawed Frog, Xenopus fraseri

The Fraser’s clawed frog also known as Fraser’s platanna is wide spread with an abundant population throughout Angola, Cameroon, Central African Republic, Republic of the Congo, Democratic Republic of the Congo, Equatorial Guinea, Gabon and Rwanda. The habitat of this species of frog is tropical and subtropical lowlands where there are forests, rivers, freshwater lakes, marshes, ponds and streams. The Fraser’s clawed frog is a water dependent species using it for living and...

African Clawed Frog, Xenopus laevis
2014-08-18 16:16:15

The African clawed frog is found in its natural habitat throughout Africa. However, it has been introduced in North America, South America and Europe. This species is fully aquatic and is found abundantly in ponds, lakes, and rivers. The body color of the African clawed frog is a greenish grey and the skin is smooth and slippery with blotches of grey or brown on the back. The belly is a cream colored with a yellow tint. The average length of this species is five inches. The body and head...

Auckland Island Pig
2014-08-07 11:44:58

The Auckland Island pig is a breed of feral pig that resides on Auckland Island in New Zealand. During the eighteenth and nineteenth centuries, domestic pigs were released onto many sub-Antarctic islands, including Auckland Island, by Europeans who wanted stranded sailors or whalers to have a steady supply of food when visiting these uninhabited islands. This process began in 1807 and after several other releases occurring between 1840 and the 1890’s, the pigs began to establish a healthy...
