اشعار ریچ، به عنوان اشعاری که همیشه در حال تغییر و دگرگونی هستند، تجسمی از رشد و دگرگونیِ انسان هستد. پایان نامه ی حاضر، با تمرکز بر روی مراحل سیر شعری ریچ از تغییری در دنیا به عکس هایی فوری از یک عروس، سپس به شیرجه به درون کشتی شکسته و در نهایت به صبری عجیب مرا تا اینجا آورده، به بررسی این مراحل در قالب نظر شوالتر در رابطه با سه مرحله ی پیشرفت ادبی زنان یعنی مرحله ی زنانه، زن گرا و زن محور می پ...
15 صفحه اولExpression of the Arabidopsis floral homeotic gene AGAMOUS is restricted to specific cell types late in flower development.
Mutations in the AGAMOUS (AG) gene cause transformations in two adjacent whorls of the Arabidopsis flower. Petals develop in the third floral whorl rather than the normal stamens, and the cells that would normally develop into the fourth whorl gynoecium behave as if they constituted an ag flower primordium. Early in flower development, AG RNA is evenly distributed throughout third and fourth wh...
متن کاملRepression of AGAMOUS by BELLRINGER in floral and inflorescence meristems.
A common aspect of gene regulation in all developmental systems is the sustained repression of key regulatory genes in inappropriate spatial or temporal domains. To understand the mechanism of transcriptional repression of the floral homeotic gene AGAMOUS (AG), we identified two mutations in the BELLRINGER (BLR) gene based on a striking floral phenotype, in which homeotic transformations from s...
متن کاملFunctional diversification of AGAMOUS lineage genes in regulating tomato flower and fruit development
AGAMOUS clade genes encode MADS box transcription factors that have been shown to play critical roles in many aspects of flower and fruit development in angiosperms. Tomato possesses two representatives of this lineage, TOMATO AGAMOUS (TAG1) and TOMATO AGAMOUS-LIKE1 (TAGL1), allowing for an analysis of diversification of function after gene duplication. Using RNAi (RNA interference) silencing, ...
متن کاملLEUNIG, a putative transcriptional corepressor that regulates AGAMOUS expression during flower development.
Regulation of homeotic gene expression is critical for proper developmental patterns in both animals and plants. LEUNIG is a key regulator of the Arabidopsis floral homeotic gene AGAMOUS. Mutations in LEUNIG cause ectopic AGAMOUS mRNA expression in the outer two whorls of a flower, leading to homeotic transformations of floral organ identity as well as loss of floral organs. We isolated the LEU...
