بررسی اکولوژیکی ازتوباکتر در دو منطقه مرتعی آذربایجان و اثر تلقیح آن روی رشد و تغذیه معدنی گیاه گندم
A great number of studies have been conducted on the role of Azotobacter - a free living N2-fixer - in agricultural soils, but our information is lacking on the importance of Azotobacter in pasture soils. This research was conducted to study the relationship between ecological and edaphical factors with the population of the bacteria in soil. Soil samples were taken from two sites in Azarbaidja...
Plant stature in temperate cereals is predominantly controlled by tillering and plant height as complex agronomic traits, representing important determinants of grain yield. This study was designed to reveal the genetic basis of tillering at five developmental stages and plant height at harvest in 218 worldwide spring barley (Hordeum vulgare L.) accessions under greenhouse conditions. The acces...
Rice tillering is a multigenic trait that influences grain yield, but its regulation molecular module is poorly understood. Here we report that OsMADS57 interacts with OsTB1 (TEOSINTE BRANCHED1) and targets D14 (Dwarf14) to control the outgrowth of axillary buds in rice. An activation-tagged mutant osmads57-1 and OsMADS57-overexpression lines showed increased tillers, whereas OsMADS57 antisense...
some new water-soluble schiff base complexes of na2[m(5-so3-1,2-salophen)].nh2o; (5-so3-1,2-salophen = n,n’-bis(5-sulphosalicyliden)-1,2-phenylendiamine); na2[m(5-so3-2,3-salpyr)(h2o)n].2h2o; (5-so3-2,3-salpyr = n,n’-bis(5-sulphosalicyliden)-2,3-diaminopyridine); and na2[m(5-so3-3,4-salbenz)(h2o)n].nh2o; (5-so3-3,4-salbenz = n,n’-bis(5-sulphosalicyliden)-3,4-diaminobenzophenon); where m = cu, n...
the clay crosslinked hydrogel nanocomposites were synthesized by graft copolymerization of acrylamide and itaconic acid in the presence of different amounts of laponite using ammonium persulfate and n,n,n',n'-tetramethylethylene diamine )temed) as a free radical initiator and catalyst, respectively. the xrd patterns of nanocomposites showed that the clay layers are completely exfolia...
در این بررسی که طی سالهای 1388 و 1389 انجام گرفت، در مجموع 18 گونه متعلق به 12 جنس و 9 خانواده جمع آوری شد که از این تعداد دو گونه برای اولین بار از ایران و نه گونه برای اولین بار از دنیا گزارش میشوند که به ترتیب با علامت (*) و (**) مشخص شدهاند. نام میزبان یا میزبانهای هر یک از کنهها در داخل کروشه [] درج شده است. کلیه نمونهها در کلکسیون کنه شناسی گروه حشره شناسی کشاورزی دانشگاه تربیت مدرس تهران...
Abstract Background Amino acids, which are transported by amino acid transporters, the major forms of organic nitrogen utilized higher plants. Among 19 Acid Permease transporters (AAPs) in rice, only a small number these genes have been reported to influence rice growth and development. However, whether other OsAAPs responsible for development is unclear. Results In this study, we demonstrate t...
Rice grassy stunt virus (RGSV) is a serious threat to rice production in Southeast Asia. RGSV is a member of the genus Tenuivirus, and it induces leaf yellowing, stunting, and excess tillering on rice plants. Here we examined gene responses of rice to RGSV infection to gain insight into the gene responses which might be associated with the disease symptoms. The results indicated that (1) many g...
Drought stress and phosphorus (P) deficit decrease soybean P nitrogen (N) accumulation, which limits productivity. Therefore, traits related to N uptake and/or their efficient utilization are important for adaptation P- water-deficit conditions. We hypothesize that increasing nodulation enhance uptake, improving use efficiency (PUE NUE) the of drought low To test this hypothesis, we selected fo...
