High survival frequencies at low herbicide use rates in populations of Lolium rigidum result in rapid evolution of herbicide resistance

Article Abstract:

The detailed dose-response experiments. Large differences in the dose-response characteristics of diclofop-methyl selected and unselected lines of five Lolium rigidum populations confirmed that high initial levels of survival to field recommended rates of diclofop-methyl were the result of heritable variations in herbicide sensitivity.

Molecular evolution: Lateral gene transfer and other possibilities

Article Abstract:

Lateral gene transfer occurs in higher plants, where disparate lineages occasionally exchange parts of their genetic fabric. The other possibility is the unusual polymerase chain reaction (PCR) products from Amborella stem from substrates somewhere in its genome, but that the unusual trees are not due to (LGT).

Non-neutral evolution of the major histocompatibility complex class II gene DRB1 in the sac-winged bat Saccopteryx bilineata

Article Abstract:

The article presents that recombination gives rise to new alleles at the DRB locus of the sac-winged bat Saccopteryx bilineata which are maintained in the population through balancing selection.
