Germplasm Phenotype:

• bah1-D  — Exhibits spontaneous cell death in leaves after bolting and increased salicylic acid levels and localized cell death after inoculation with Pst DC3000.
• nla  — In contrast to wild type, anthocyanin accumulation did not occur in the senescing mutant rosette leaves.
• nla  — Mutants failed to adapt to the conditions of nitrogen limitation and started senescence much earlier and more rapidly than did wild-type plants supplied with 3 mM nitrate: mutant plants supplied with 10 mM nitrate had a similar pattern of growth and development to wild type. When the nitrate concentration was reduced to 3 mM, the mutant plants started senescence in the fifth rosette leaf at 24 DAG, and after this point senescence progressed rapidly with all rosette leaves showing senescence symptoms at 26 DAG, and the whole rosette dying at 32 DAG. In contrast, wild-type plants displayed no senescence symptoms in the fifth rosette leaf until 32 DAG. In wild-type plants, the process of senescence proceeded slowly and gradually from the fifth to the youngest rosette leaves, and it took at least 2 weeks for all rosette leaves to show the senescence symptoms.
• nla  — The cauline leaves in the mutant plants started senescence at 28 DAG, at least 10 days earlier than those in the wild-type plants. Further, the developing mutant siliques initiated senescence in their tips at 32 DAG, while the wild-type siliques showed no senescence symptoms throughout their development but accumulated abundant anthocyanin which was not observed in the mutant siliques.
• nla  — The early senescence process was arrested when nitrate was added after depletion.
• nla  — The occurrence (at 24 DAG) and progression (at 28 DAG) of senescence in mutant rosette leaves were not accompanied by a significant reduction in the amounts of nitrogen-containing compounds: nitrate, total amino acids, soluble proteins, and total nitrogen. By contrast, they were largely reduced in the wild-type plants.
• nla  — With the reduction of the nitrate concentration to 1 mM, the occurrence of the senescence phenotype in the rosette leaves of mutant plants was accelerated to 20 DAG, and severe senescence in the developing mutant siliques resulted in their death around 30 DAG without producing viable seeds. Under the same growth condition (1 mM nitrate), wild-type plants did not start senescence in their rosette leaves until 26 DAG, and produced fecund siliques.
