Germplasm Phenotype:

• tso2-1  — At the seedling stage, tso2-1 mutants were similar to the wild type, with normal roots, cotyledons, and young leaves. Abnormalities first appeared in the fifth rosette leaf and persisted in all subsequent leaves, floral organs, and siliques. The abnormalities included white sectors in green organs, uneven thickness, rough surfaces, and irregular margins of leaves or floral organs. Stamens occasionally exhibited carpel characteristics indicating homeotic transformation. The rough and uneven sepals apparently resulted from abnormally enlarged cells as well as cell clusters projecting above the epidermis. The white sectors appeared to result from an absence of chloroplasts in patches of mesophyll cells and the formation of large air spaces or tiny cells in subepidermal cell layers. Occasionally, tso2 mutants exhibited fasciated stems on which a single SAM, a group of self-renewing cells at the shoot tip, was enlarged and split into multiple SAMs. Finally, tso2 mutants exhibited reduced fertility, with ;29% aborted seeds. tso2-1 floral tissues were found to contain significantly reduced levels of all four dNTPs. tso2-1 exhibited slightly increased sensitivity to UV-C light, but only at high UV-C light levels.
• tso2-1 rnr2a-1  — tso2-1 rnr2a-1 seedlings did not develop beyond the two- to four-leaf stage. Their SAMs were terminated with callus-like cells, and their leaves exhibited massively. Exhibited significantly increased sensitivity to UV-C light.
