Genome-wide non-mendelian inheritance of extra-genomic information in Arabidopsis

Article Abstract:

Arabidopsis plants homozygous for recessive mutant alleles of the organ fusion gene HOTHEAD (HTH) could inherit allele-specific DNA sequence information that was not present in the chromosomal genome of their parents but was present in the previous generation. The genetic restoration events are the result of a template-directed process that makes use of an ancestral RNA-sequence cache.

APL regulates vascular tissue identity in Arabidopsis

Article Abstract:

The Altered Phloem development (APL) expression profile is consistent with a key role in phloem development. Studies suggest that APL has a dual role both in promoting phloem differentiation and in repressing xylem differentiation during vascular development.
