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

Many insect pest species also transmit viruses. The sapsucking species are effective virus vectors, delivering virus particles directly into the vascular tissue, thereby permitting their rapid dissemination throughout the plant

An individual carrying the allele can pass copies of it to his or her own children. This is the allele’s direct fitness. The allele can also pass extra copies of itself to the next generation as the result of the increased fitness of relatives that benefit from the altruistic individual’s actions. This is the allele’s indirect fitness.

Detyrosylated microtubules are more stable, because they are more resistant to depolymerization by kinesin-13 and related proteins.
