The genome of Thellungiella parvula, a halophytic relative of Arabidopsis (Arabidopsis thaliana), is being assembled using Roche-454 sequencing. Analyses of a 10-Mb scaffold revealed synteny with Arabidopsis, with recombination and inversion and an uneven distribution of repeat sequences. T. parvula genome structure and DNA sequences were compared with orthologous regions from Arabidopsis and p...
African-American (AA) men experience an increased risk of developing prostate cancers as well as increased mortality following treatment as compared to European-American (EA) men. The aim of our study was to identify biological factors with the potential to predispose AA men to prostate tumor progression and metastasis. To identify cancer-specific gene expression patterns in AA men, we establis...
سابقه و هدف: سیستم های sos مهم ترین نقش را در تحمل شوری گیاه دارد. این سیستم در آرابیدوپسیس تالیانا به عنوان یک سیستم پیام رسانی سلول در مسیرهای تحمل به تنش شوری عمل می کند. مواد و روش ها: در این تحقیق با بررسی توالی ژن sos1 در آرابیدوبسیس از پایگاه tair، ebi، ncbi، plantcare وexpasy و هم چنین جهت بررسی روابط این ژن در سیزده گونه گیاهی مختلف، میزان همولوژی آن ها از لحاظ میزان تشابه با نرم افزار...
For plants growing in highly saline environments, accumulation of sodium in the cell cytoplasm leads to disruption of metabolic processes and reduced growth. Maintaining low levels of cytoplasmic sodium requires the coordinate regulation of transport proteins on numerous cellular membranes. Our previous studies have linked components of the Salt-Overly-Sensitive pathway (SOS1-3) to salt toleran...
ژن آنتی پورترسدیم/پروتون sos1 از گیاه آلوروپوس تحت تنش شوری ناشی از کلرید سدیم جداسازی شد.cdna جداسازی شده با طول 3981 جفت باز بوده و حاوی چارچوب قرائت آزاد فرضی 3438 جفت بازی میباشد. توالی آمینواسیدی sos1 مشابهت بالایی با ترانسپورترهای گیاهی sos1 نشان میدهد. پیشبینی میشود alsos1 دارای 12 ناحیه فراغشایی فرضی در انتهای آمینی و دم طویل آبگریز سیتوپلاسمی در انتهای اسیدی باشد. در این مطالعه، ا...
Engineered abiotic stress resistance is an important target for increasing agricultural productivity. There are concerns, however, regarding possible ecological impacts of transgenic crops. In contrast to the first wave of transgenic crops, many abiotic stress resistance genes can initiate complex downstream changes. Transcriptome profiling has been suggested as a comprehensive non-targeted app...
An analysis of the salinity tolerance of 354 Arabidopsis thaliana accessions showed that some accessions were more tolerant to salt shock than the reference accession, Col-0, when transferred from 0 to 225 mM NaCl. In addition, several accessions, including Zu-0, showed marked acquired salt tolerance after exposure to moderate salt stress. It is likely therefore that Arabidopsis plants have at ...
Endothelin-1 (ET-1) induces cell proliferation and differentiation through multiple G-protein-linked signaling systems, including p21ras activation. Whereas p21ras activation and desensitization by receptor tyrosine kinases have been extensively investigated, the kinetics of p21ras activation induced by engagement of G-protein-coupled receptors remains to be fully elucidated. In the present stu...
This work investigates the role of cytosolic Na+ exclusion in roots as a means of salinity tolerance in wheat, and offers in planta methods for the functional assessment of major transporters contributing to this trait. An electrophysiological protocol was developed to quantify the activity of plasma membrane Na+ efflux systems in roots, using the microelectrode ion flux estimation (MIFE) techn...
