Abstract STOP1 (sensitive to proton rhizotoxicity1) is a master transcription factor that governs the expression of set regulatory and structural genes involved in resistance aluminum low pH ( i.e ., proton) stresses Arabidopsis. However, mechanisms networks underlying STOP1-mediated are largely unclear. Here, we report low-pH severely inhibited root growth stop1 plants by suppressing meristem ...

BACKGROUND AND AIMS The typical rootless linear shoots of aquatic carnivorous plants exhibit clear, steep polarity associated with very rapid apical shoot growth. The aim of this study was to determine how auxin and cytokinin contents are related to polarity and shoot growth in such plants. METHODS The main auxin and cytokinin metabolites in separated shoot segments and turions of two carnivo...
reinsurance is widely recognized as an important instrument in the capital management of an insurance company as well as its risk management tool. this thesis is intended to determine premium rates for different types of reinsurance policies. also, given the fact that the reinsurance coverage of every company depends upon its reserves, so different types of reserves and the method of their calc...
با توجه به تولید روزافزون نانو ذرات مغناطیسی و کاربرد مفید آن در سیستم های بیولوژی، تاکنون مطالعات کم تری در زمینه اثرات جانبی این مواد در بدن موجودات زنده صورت گرفته است. بررسی فاکتورهای خونی و مشخص کردن تابلوی خونی هر جاندار علاوه بر آن که به عنوان یک شاخص فیزیولوژیک مهم به شمار می رود، در تشخیص بیماریها نیز میتواند بسیار مفید واقع شود. 200عدد ماهی کپورمعمولی دریای خزر با وزن میانگین ...
the aim of this study was to identify the problems of translating markedness structures from english to persian in order to look closely at what possible difficulties translators may face. it also seeks to probe the strategies applied accordingly by iranian translators in translating them. from three translation of blindness novel, the sentences with marked structures were elicited and also the...
The formation of active oxygen species affects the morphogenesis of plant cells and tissues and inhibits the process of development during in vitro cultivation. Cytokinins have been found to be effective free radical scavengers. Peroxidase (EC 1.11.1.7) is among enzymes expressing antioxidative functions. The present study was focused on the effect of N6-benzyladenine (BA), and N1-(2-chloro-4-p...
teachers beliefs have usually been left unattended in the realm of educational research in iranian context. one of those beliefs which seems to impact teachers performance in the classroom is their sense of self-efficacy, which refers to teachers belief in their ability to enhance student achievement and in bringing about positive learning outcomes. the present study aimed to investigate the pr...
An efficient genetically stable regeneration protocol with increased phytochemical production has been established for Dendrobium nobile, a highly prized orchid for its economic and medicinal importance. Protocorm like bodies (PLBs) were induced from the pseudostem segments using thidiazuron (TDZ; 1.5 mg/l), by-passing the conventional auxin-cytokinin complement approach for plant regeneration....
Grass pea (Lathyrus sativus L.) is highly nutritious and protein rich legume crop; however, presence of ODAP (β-NOxalyl-L-α, β-diaminopropionic acid) has restricted its use for human and animal consumption. There is need for accelerated breeding of low or zero ODAP cultivars to ensure safer and wider use of grass pea through conventional and biotechnological approaches. The study investigated s...
