Paving a road toward mitochondrial plant cell factories

Scientists have devised a new strategy for selectively delivering genes into the mitochondria of plant cells by using a simple combination of cell-penetrating and mitochondria-targeting peptides. This work lays the groundwork for the rational design of peptide-based gene carriers with the potential to create a new field of 'mitochondria engineering', which could enable the creation of mitochondria-based plant cell factories for the creation of bio-polymers and bio-fuels.

Damaged DNA amplified

Researchers have succeeded for the first time in amplifying gene samples containing DNA adducts while retaining references to these adducts. This type of amplification is a prerequisite for the majority of technologies used by researchers to determine a gene's DNA sequence.

Bacteria could be rich source for making terpenes

New research shows that the genetic capacity of bacteria to make terpenes is widespread. Using a specialized technique to sift through genomic databases for a variety of bacteria, the researchers found 262 gene sequences that likely code for terpene synthases - enzymes that catalyze the production terpenes.

A clear, molecular view of how human color vision evolved

Many genetic mutations in visual pigments, spread over millions of years, were required for humans to evolve from a primitive mammal with a dim, shadowy view of the world into a greater ape able to see all the colors in a rainbow. Now, after more than two decades of painstaking research, scientists have finished a detailed and complete picture of the evolution of human color vision.
