Germplasm Phenotype:

• CS71657  — Reduced seed production.
• CS71660  — Strongly reduced light-induced endogenous PIF3 mobility shift and degradation, and reduced light-induced degradation of phyB. Short hypocotyl in continuous red light (Rc). Reduced seed production.
• CS71747  — Reduced light-induced PIF3 phosphorylation and degradation; light-induced phyB degradation also strongly reduced. Hypersensitive to red light; short hypocotyl and enhanced cotyledon expansion in continuous R light. Very small seed set, short siliques (unpublished observations).
• CS71748  — Red-light hypersensitive phenotype of the ppk123 triple mutant (CS71747) is strongly suppressed in the phyB mutant background. Long hypocotyl in continuous R light, open cotyledons. Very small seed set (non-published observation).
• ael124  — hypersensitive response to ABA, reduced seed germination ratio or green cotyledon percentage, suppressed lateral root elongation under ABA treatment, reduced stomatal aperture under ABA treatment, reduced germination under salinity
• ael134  — hypersensitive response to ABA, reduced seed germination ratio or green cotyledon percentage, suppressed lateral root elongation under ABA treatment, reduced stomatal aperture under ABA treatment, reduced germination under salinity
