‘Flip-flop’ switch discovered behind key cellular process

For organisms to grow and develop, they must produce tissues with distinct functions, each one made up of similar cells. These different tissues are derived from stem cells. How stem cells divide to create new cell types is known as asymmetric cell division, and is obviously crucial to the overall development of the organism. In [...]

How the same plant species can programme itself to flower at different times in different climates

Researchers led by Professor Caroline Dean have uncovered the genetic basis for variations in the vernalization response shown by plants growing in very different climates, linking epigenetic mechanisms with evolutionary change. Vernalization is a period of prolonged cold that some plants require before they will flower. This ensures that they only produce flowers after the [...]

Plant research reveals new role for gene silencing protein

A DICER protein, known to produce tiny RNAs in cells, also helps complete an important step in gene expression, according to research on Arabidopsis thaliana. The expression of a gene, when an organism’s DNA is transcribed into a useable product, requires activation via a promoter or an external trigger. Plant research to be published in [...]

Flowers in February

  This winter has been so mild we wouldn’t be surprised if plants were blooming in February! But what happens in a normal season? Just how do plants control when and how they flower? Find out how research at the John Innes Centre on flowering in weeds contributes to food security. Talks included a look [...]

The breathtaking dance of plants

The breathtaking dance of plants

  The way in which plants space out the pores through which they breathe depends on keeping a protein active during stem cell growth, according to John Innes Centre scientists. Plant pores, called stomata, are essential for life. When they evolved about 400 million years ago, they helped plants conquer the land. Plants absorb carbon [...]

How an ‘evolutionary playground’ brings plant genes together

How an ‘evolutionary playground’ brings plant genes together

Plants produce a vast array of natural products, many of which we find useful for making things such as drugs. There are likely to be many other plant natural products that remain undiscovered or under-exploited, and research from The John Innes Centre, which is strategically funded by the Biotechnology and Biological Sciences Research Council (BBSRC), [...]

Dissecting the genomes of crop plants to improve breeding potential

Dissecting the genomes of crop plants to improve breeding potential

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 [...]

New projects to develop improved crops for food security

New projects to develop improved crops for food security

The John Innes Centre will receive approximately £1million of funding for two new research projects that will help reduce yield losses in oilseed rape, and improve the efficiency of the conversion of barley grain to beer and whisky. On the morning of the first day of Cereals 2011, the Biotechnology and Biological Sciences Research Council [...]
