Only 22 tRNAs are required for mitochondrial protein synthesis. The normal codon–anticodon pairing rules are relaxed in mitochondria, so that many tRNA molecules recognize any one of the four nucleotides in the third (wobble) position, allowing four codons to be recognized by a single tRNA.

Coronatine is involved in causing stomata to open after closing in response to PAMPs, as well as in interfering with salicylic acid (SA)‐mediated defense responses.

Quorum sensing in Erwinia carotovora is mediated by N‐acylhomoserine lactones, small molecules released from the bacterial cells into the surrounding medium.

Phytoplasmas are specialized bacteria that are obligate parasites of the phloem tissue. They are mainly
spread by insects in the families Cicadellidae (leaf hoppers),
Fulgoroidae (plant hoppers), and Psyllidae (jumping plant
lice).

During infection, most bacteria remain in extracellular spaces and use a specialized mechanism, the type III secretion system (T3SS), to deliver bacterial effector proteins into the plant cell
