Plastid proteins crucial for symbiotic fungal and bacterial entry into plant roots

Article Abstract:

Two highly homologous genes from Lotus japonicus, CASTOR and POLLUX, that are indispensable for microbial admission into plant cells and act upstream of intracellular calcium spiking, one of the earliest plant responses to symbiotic stimulation are presented. Both twin proteins are localized in the plastids of root cells, indicating a previously unrecognized role of this ancient endosymbiont in controlling intracellular symbioses that evolved more lately.

Plant-fungal association: Cue for the branching connection

Article Abstract:

The chemical structure of branching factor and understanding of plant-fungi symbiosis are presented. The results suggest that the fungal signal is produced only by hyphae that have undergone the branching response, after the perception of branching factor from the host plant.

Locks, keys and symbioses

Article Abstract:

To allow bacterial entry into root hairs, association between legumes and nitrogen-fixing bacteria require molecular recognition. In legumes, the root hairs show sudden developmental switch, as soon as molecular recognition occurs between rhizobia and a plant.
