The phyB mutants are deficient in chlorophyll

phyB also appears to regulate LFRs, such as photoreversible seed germination

Mutants that lack phyA respond normally to red light, whereas mutants deficient in phyB are unable to respond to low-fluence red light

Each snRNP contains a single snRNA (100-300 nt) and several (20) proteins. The U4 and U6 snRNPs are usually found together as a di-snRNP (U4/U6) particle.
