Phylogeny of Campanuloideae (Campanulaceae) with Emphasis on the Utility of Nuclear Pentatricopeptide Repeat (PPR) Genes

BACKGROUND The Campanuloideae (Campanulaceae) are a highly diverse clade of angiosperms found mostly in the Northern Hemisphere, with the highest diversity in temperate areas of the Old World. Chloroplast markers have greatly improved our understanding of this clade but many relationships remain unclear primarily due to low levels of molecular evolution and recent and rapid divergence. Furtherm...

An empirical demonstration of using pentatricopeptide repeat (PPR) genes as plant phylogenetic tools: phylogeny of Verbenaceae and the Verbena complex.

The pentatricopeptide repeat (PPR) gene family, with hundreds of members in land plant genomes, has been recognized as a tremendous resource for plant phylogenetic studies based on publicly available genomic data from model organisms. However, whether this appealing nuclear gene marker system can be readily applied to non-model organisms remains questionable, particularly given the potential un...

The nuclear component of a cytonuclear hybrid incompatibility in Mimulus maps to a cluster of pentatricopeptide repeat (PPR) genes

Characterizing the genetic and molecular basis of hybrid incompatibilities is a first step toward understanding their evolutionary origins. We fine-mapped the nuclear restorer (Rf) of cytoplasmdependent anther sterility in Mimulus hybrids by identifying and targeting regions of the Mimulus guttatus genome containing large numbers of candidate pentatricopeptide repeat genes (PPRs). The single Me...

Signature of diversifying selection on members of the pentatricopeptide repeat protein (PPR) family in Arabidopsis lyrata

the study of aaag repeat polymorphism in promoter of errg gene and its association with the risk of breast cancer in isfahan region

چکیده: سرطان پستان دومین عامل مرگ مرتبط با سرطان در خانم ها است. از آنجا که سرطان پستان یک تومور وابسته به هورمون است، می تواند توسط وضعیت هورمون های استروئیدی شامل استروژن و پروژسترون تنظیم شود. استروژن نقش مهمی در توسعه و پیشرفت سرطان پستان ایفا می کند و تاثیر خود را روی بیان ژن های هدف از طریق گیرنده های استروژن اعمال می کند. اما گروه دیگری از گیرنده های هسته ای به نام گیرنده های مرتبط به ا...
