Creating Completely Both Male and Female Sterile Plants by Specifically Ablating Microspore and Megaspore Mother Cells
Although genetically modified (GM) plants have improved commercially important traits, such as biomass and biofuel production, digestibility, bioremediation, ornamental value, and tolerance to biotic and abiotic stresses, there remain economic, political, or social concerns over potential ecological effects of transgene flow from GM plants. The current solution for preventing transgene flow fro...

چکیده هدف اصلی تحقیق حاضر مطالعه و بررسی رابطه بین خودکارامدی شنیداری با درک شنیداری بود.همچنین رابطه درک شنیداری وخودکارآمدی شنیداری با جنسیت و رابطه خودکارامدی شنیداری با سن نیز مورد بررسی قرار گرفت.تعداد شصت زبان اموز-سی دختر و سی پسر- کانون زبان ایران در مرکز خرم آباد به صورت تصادفی انتخاب شدند. روشهای به کار رفته در جمع اوری داده ها عبارت بودند ازبرسشنامه خودکارآمدی و تست درک شنیداری لانگ...
15 صفحه اولGenetics and cytology of a genic male-sterile, female-sterile mutant from a transposon-containing soybean population.
A male-sterile, female-sterile soybean mutant (w4-m sterile) was identified among progeny of germinal revertants of a gene-tagging study. Our objectives were to determine the genetics (inheritance, allelism, and linkage) and the cytology (microsporogenesis and microgametogenesis) of the w4-m sterile. The mutant was inherited as a single recessive nuclear gene and was nonallelic to known male-st...
متن کاملNovel genetic male sterility developed in (Capsicum annuum x C. chinense) x C. pubescens and induced by HNO2 showing Mendelian inheritance and aborted at telophase of microspore mother cell stage.
A novel genetic male sterile germplasm was developed by successively crossing of (C. annuum x C. chinense) x C. pubescens and by chemical mutagenesis in pepper. The sterile anthers showed morphological abnormalities, but pistils developed normally with fine pollination capability. We investigated fertility segregation through sib-crossing of the same strains and test crossing by male sterile pl...
