Tracking whole colonies shows ants make career moves | Nature

Tracking whole colonies shows ants make career moves | Nature | CALS in the News | Scoop.it

Because all the workers in an ant colony look the same, tracking their movements and interactions by eye is fiendishly difficult. Instead, Danielle Mersch and her colleagues tagged every single worker in entire colonies and used a computer to track them, accumulating what they say is the largest-ever data set on ant interactions.

The oil palm SHELL gene controls oil yield and encodes a homologue of SEEDSTICK | Nature

A key event in the domestication and breeding of the oil palm Elaeis guineensis was loss of the thick coconut-like shell surrounding the kernel. Modern E. guineensis has three fruit forms, dura (thick-shelled), pisifera (shell-less) and tenera (thin-shelled), a hybrid between dura and pisifera1, 2, 3, 4. The pisifera palm is usually female-sterile. The tenerapalm yields far more oil than dura, and is the basis for commercial palm oil production in all of southeast Asia5. Here we describe the mapping and identification of the SHELLgene responsible for the different fruit forms.

A physical, genetic and functional sequence assembly of the barley genome : Nature

A physical, genetic and functional sequence assembly of the barley genome : Nature | CALS in the News | Scoop.it

Barley (Hordeum vulgare L.) is among the world’s earliest domesticated and most important crop plants. It is diploid with a large haploid genome of 5.1 gigabases (Gb). Here we present an integrated and ordered physical, genetic and functional sequence resource that describes the barley gene-space in a structured whole-genome context.
