How leaves talk to roots     2018/09/25 16:00

New findings show that a micro RNA from the shoot keeps legume roots susceptible to symbiotic infection by downregulating a gene that would otherwise hinder root responses to symbiotic bacteria. These findings help us understand what it takes to make nitrogen-fixing symbiosis efficient, and what we need to do to exploit it agronomically.

Genome duplication drives evolution of species     2018/09/25 12:51

Polyploid plants have a duplicate set of chromosomes. As a result, large-scale genetic changes are therefore possible in the new species, making it more adaptable in comparison with the parental species, as has now been demonstrated by researchers using rockcress.
