Large-scale mRNA transfer between (Chenopodiaceae) and herbaceous root holoparasite (Orobanchaceae).

Exchanges of mRNA were shown between host and stem parasites but not root parasites. (Orobanchaceae) is a holoparasitic herb which parasitizes on the roots of woody plant (Chenopodiaceae). We used transcriptome sequencing and bioinformatic analyses to identify nearly ten thousand mobile mRNAs.

Decoy engineering of the receptor-like cytoplasmic kinase StPBS1 to defend against virus infection in potato.

Potato virus Y (PVY) is an important pathogen of potato (Solanum tuberosum). Although the PBS1-RPS5 immune system is well documented in Arabidopsis thaliana, it has not been reported in potato. In Arabidopsis, the bacterial effector AvrPphB cleaves AtPBS1 to trigger an immune response.

Tomato SlBL4 plays an important role in fruit pedicel organogenesis and abscission.

Abscission, a cell separation process, is an important trait that influences grain and fruit yield. We previously reported that BEL1-LIKE HOMEODOMAIN 4 (SlBL4) is involved in chloroplast development and cell wall metabolism in tomato fruit. In the present study, we showed that silencing SlBL4 resulted in the enlargement and pre-abscission of the tomato (Solanum lycopersicum cv.

Host sunflower-induced silencing of parasitism-related genes confers resistance to invading Orobanche cumana.

Orobanche cumana is a holoparasitic plant that attaches to host-plant roots and seriously reduces the yield of sunflower (Helianthus annuus L.). Effective control methods are lacking with only a few known sources of genetic resistance.
