Unlike higher plants, the dioecious liverwort, Marchantia polymorpha, has uniquely small sex chromosomes, with X chromosomes present only in female gametophytes and Y chromosomes only in male gametophytes. We have constructed respective genomic libraries for male and female plantlets using a P1-derived artificial chromosome (pCYPAC2). With an average insert(More)
The corolla of Petunia ‘Magic Samba’ exhibits unstable anthocyanin expression depending on its phosphorus content. Phosphorus deficiency enhanced post-transcriptional gene silencing of chalcone synthase - A in the corolla. Petunia (Petunia hybrida) ‘Magic Samba’ has unstable red–white bicolored corollas that respond to nutrient deficiency. We grew this(More)
A total of 935 expressed sequence tags (ESTs) from male immature sexual organ were determined, of which 600 ESTs were assembled into 110 non-redundant groups, resulting in 445 unique EST sequences. Of these, 244 sequences shared significant similarities to known nucleotide or amino acid sequences in other organisms. The remaining 201 unique sequences showed(More)
