Germplasm Phenotype:

• CS72464  — elevated transient nonphotochemical quenching (NPQ) under nonsaturating light conditions, photosystem II damage and decreased biomass under long-term fluctuating light stress; reduced sodium tolerance
• SALK_008491  — Transient high NPQ in SALK_008491 is caused by loss of PGDH3.
• nhd1-2  — Homozygotes not recoverable possibly due to linked lethal gene.
