Variation in restorer genes and primary sexual investment in gynodioecious Plantago coronopus: the trade-off between male and female function.
In many gynodioecious species the nuclear inheritance of male fertility is complex and involves multiple (restorer) genes. In addition to restoring plants from the female (male sterile) to the hermaphrodite (male fertile) state, these genes are also thought to play a role in the determination of the quantity of pollen produced by hermaphrodites. The more restorer alleles a hermaphroditic plant ...
متن کاملGenetics of Male Sterility in Gynodioecious Plantago coronqPus . 11 . Nuclear Genetic Variation Hans
Inheritance of male sterility was studied in the gynodioecious species Plantago coronopus using five plants and their descendants from an area of -50 m' from each of four locations. In each location, crosses between these five plants yielded the entire array of possible sex phenotypes. Both nuclear and cytoplasmic genes were involved. Emphasis is placed on the nuclear (restorer) genetics of two...
متن کاملAssociation of Alu Insertion Polymorphism in Progesterone Receptor Gene with Risk of Multiple Sclerosis
Background and purpose: Multiple sclerosis (MS) is a chronic autoimmune disease in which the myelin sheaths of nerve cells in the brain and spinal cord are damaged. The prevalence of disease is higher in women and it seems that sex hormones, which usually exert their effects through receptors, are involved in susceptibility to MS. Considering the functional role of Alu insertion 306 bp polymorp...
متن کاملNeurofilament light chain gene polymorphism and risk of multiple sclerosis in Iranian patients
Background: Multiple sclerosis (MS) is a chronic disease characterized by inflammation and degeneration of the central nervous system (CNS). High levels of Neurofilament light chain (NFL) and Neurofilament heavy chain (NFH) in cerebrospinal fluid (CSF) have been associated with a wide range of neurological diseases including MS. Subjects and methods: Peripheral blood samples were collected from...
متن کاملThe Association of Vitamin D Receptor Gene BsmI Polymorphism with Multiple Sclerosis in Iranian Patients
Background & Aims: 1,25-dihydroxyvitamin D3 (1,25 (OH)2 D3), the biologically active form of vitamin D, exerts an immunosuppressive effect through binding to its specific nuclear receptor. The present case-control study was done to examine the possible association of BsmI polymorphism in vitamin D receptor gene (VDR gene) with severity of multiple sclerosis (MS). Methods: 267 Iranian patients w...
