با استفاده از تکنیک پی¬سی¬آر یک ایزوفرم جدید رمز کننده عامل رونویسی انگشت روی از گیاه هالوفیت aeluropus littoralis جداسازی، همسانه سازی و توالی یابی شد. برای این منظور با استفاده از یک جفت آغازگر که بر اساس توالی ژن alsap1 طراحی شده بود اقدام به جداسازی ناحیه رمز شونده ژن alsap2 شد. طی واکنش پیسیآر یک قطعه حدود 530 جفت بازی از ژنوم گیاه aeluropus littoralis تکثیر شد. قطعه تکثیر شده همسانه ساز...
Phytoremediation is an eco-friendly and low cost potential strategy for cleaning up of heavy metals from contaminated soils. Selection of promising plant is an important approach for successful phytoremediation. In two separate pot culture experiments, five levels of soil cadmium (Cd) concentrations as 15, 30, 60, 120 and 240 mg Cd kg soil and five levels of lead (Pb) including 500, 1000, 2000,...
Application of wild type crops or wild relatives’ cultivars that are halophyte in plant breeding program would provide better results in order to develop cultivars that are resistant toward drought as well as salinity. Recently, Aeluropus littoralis has attracted the attention of researcher in order to identify novel genes and their regulatory elements that are involved in salinity stress....
Background: Polycyclic aromatic hydrocarbons (PAHs), which consist of fused conjugated aromatic rings, not only are toxic to humans and other living organisms, but will also pollute groundwater. These compounds can be point source or non-point source and are one of the most widespread organic pollutants. Some of them are suspected carcinogens and are linked to other health problems. This study ...
Plants are naturally exposed to frequent changes in environmental conditions such as salt stress affecting their growth and development, and consequently a considerable reduction in total productivity. Monodehydroascorbate reductase (MDHAR), a key enzyme in ascorbate-glutathione cycle, serves as an important antioxidative enzyme in scavenging of reactive oxygen spices (ROS). In this study, ...
We report here the isolation and functional analysis of AlTMP1 gene encoding a member of the PMP3 protein family. In Aeluropus littoralis, AlTMP1 is highly induced by abscisic acid (ABA), cold, salt, and osmotic stresses. Transgenic tobacco expressing AlTMP1 exhibited enhanced tolerance to salt, osmotic, H₂O₂, heat and freezing stresses at the seedling stage. Under greenhouse conditions, the tr...
به منظور جداسازی ژن رمز کننده na+/h+ آنتی پورتر واکوئلی از گیاه هالوفیتaeluropus littoralis، rnaی کل از ریشه، ساقه و برگ گیاه استخراج و از روی آن cdnas ساخته شد. با استفاده از آغازگرهای اختصاصی برای ژن مورد نظر ازcdnasی تهیه شده از rnaی ریشه، ناحیه رمزشونده ژن رمز کننده ی na+/h+ آنتی پورتر واکوئلی(alnhx2) توسط تکنیک race جداسازی شد. قطعه جدا شده 1538 جفت باز بوده و شامل یک چهارچوب خوانش باز (or...
lignin is one of the major characteristics of plant secondary cell wall that provides structural rigidity for the cells and tissues and hydrophobicity to tracheary elements. internode tissues of aeluropus littoralis as a halophyte grass were sampled at different developmental stages (from the first to the fifth internodes ) and under different nacl concentrations. the influences of nacl and int...
