Variation in Thickness of Embryo Covering Structures and Their Role in the Regulation of Seed Physiological Dormancy of Chenopodium hircinum (Amaranthaceae)

Chenopodium hircinum, the putative wild ancestor of quinoa, is a source of traits that could improve the tolerance of crop quinoa to high temperatures.However, seeds of C.hircinum have physiological dormancy (PD), which is an obstacle for plant propagation and use in breeding programs.We studied the intraspecific variability in morpho-anatomical tr

Methylation of the claudin 1 promoter is associated with loss of expression in estrogen receptor positive breast cancer.

Downregulation of the tight junction protein claudin 1 is a frequent event in breast cancer and is associated with recurrence, metastasis, and reduced survival, suggesting a tumor suppressor role for this protein.Tumor suppressor genes are often epigenetically silenced in cancer.Downregulation of claudin 1 via DNA promoter methylation may thus be a
