Abstract:
... Plant intracellular immune receptors known as NLR (nucleotide‐binding leucine‐rich repeat) proteins confer immunity and cause cell death. Plant NLR proteins that directly or indirectly recognize pathogen effector proteins to initiate immune signalling are regarded as sensor NLRs. Some NLR protein families function downstream of sensor NLRs to transduce immune signalling and are known as helper NLR ...

The disease can cause up to 30% losses in seed yield. Unlike many Epichloë species that are seed transmitted, it is unclear how infection of orchardgrass by E. typhina occurs in the field, or how the disea ...
