Background: Legume roots show a remarkable plasticity to adapt their architecture to biotic and abiotic constraints, including symbiotic interactions. However, global analysis of miRNA regulation in roots is limited, and a global view of the evolution of miRNA-mediated diversification in different ecotypes is lacking.

Cloud computing is a relatively new concept that holds significant promises for the future development and delivery of computer resources to secondary or basic education in South Africa, especially in schools most affected by the digital divide. The aim of this paper is to briefly review the extent to which cloud computing applications and services currently used by secondary education systems in developed countries around the world can be used to help breach the digital divide that currently exists in the secondary (basic) education sector in South Africa. The authors believe that South Africa has the required technology and skills to bridge the digital divide in secondary education and by doing so set the pace for the rest of the African continent. All it lacks is the political will and determination to do so.
