Germplasm Phenotype:

• CS72368  — low fluorescence phenotype (severely decreased Fo and Fm)
• CS72369  — low fluorescence phenotype (mildly decreased Fo and Fm)
• CS72370  — impaired qH relaxation after cold and high light treatment (6 C and 1600 uE)
• CS72371  — impaired qH relaxation after cold and high light treatment (6 C and 1600 uE)
• CS72372  — overproduces leaves with short petioles (likely due to a nearby mutation linked to the T-DNA insertion); impaired qH relaxation after cold and high light treatment (6 C and 1600 uE)
• CS72373  — low fluorescence phenotype; constitutively quenched; displays features typically found in shade and low-light-acclimated plants, including reduced growth, thinner leaves, a lower chlorophyll a/b ratio and more thylakoid stacking
• CS72374  — mildly decreased fluorescence and chlorophyll a/b ratio
• CS72375  — low fluorescence phenotype; constitutively quenched; displays features typically found in shade and low-light-acclimated plants, including thinner leaves, a lower chlorophyll a/b ratio and more thylakoid stacking
• CS72376  — ROQH1 overexpression returns growth and NPQ to wild-type Col-0 levels
• CS72377  — ROQH1 overexpression returns NPQ to WT Col-0 levels, but fails to rescue roqh1-3 developmental phenotype (overproduction of leaves with short petioles)
• CS72378  — decrease in NPQ levels after cold and high light treatment (6 C and 1600 uE)
• CS72380  — low fluorescence phenotype (reduced Fo and Fm); reduced growth
• roqh1-1  — roqh1 plants have impaired qH relaxation after induction by a cold and high light treatment (6°C and 1600&
• roqh1-2  — The phenotype of roqh1-2 and soq1 roqh1-2 is intermediate. The roqh1-2 allele has golden seeds.
• roqh1-3  — The relaxation phenotype of roqh1-3 is the most severe. soq1 roqh1-3 is similar to soq1 roqh1-1. roqh1-3 overproduces leaves with short petioles due to a nearby mutation linked to the T-DNA insertion.
