Using genetic lineage tracing, tumour cells are traced in vivo in an unperturbed solid tumour; in a carcinogen-induced papilloma mouse model, cells in these benign lesions are found to mirror the clonal hierarchy organization of normal tissue.

A gene that is present in phosphate-deficiency-tolerant rice but absent from modern rice varieties is characterized and named phosphorus-starvation tolerance 1 (PSTOL1); overexpression of PSTOL1 in rice species that naturally lack this gene confers tolerance to low phosphorus conditions, a finding that may have implications for agricultural productivity in rice-growing countries.
