The hydrogenosome's murky past

Article Abstract:

Hydrgenosomes are doubly-membraned and produce ATP and hydrogen, hence suggestions that they are anaerobic derivatives of mitochondria. The missing link between hydrogenosomes and mitochondria also has remnants of electron transport chain characteristics of an aerobic lifestyle.

Gene transfer to plants by diverse species of bacteria

Article Abstract:

Several species of bacteria outside the 'Agrobacterium' genus, which can be modified to mediate gene transfer to a number of diverse plants, is shown. When suitably modified, 'Agrobacterium' becomes the most effective vector for gene transfer in plant biotechnology.

Gene exchange by design

Article Abstract:

Gene transfer from bacteria to plants was thought to be limited to the bacterial genus 'Agrobacterium'. But other bacterial groups also contain species capable of interkingdom genetic exchange.
