Cellular events of strigolactone signalling and their crosstalk with auxin in roots.
Strigolactones are a new group of plant hormones that suppress shoot branching. In roots, they regulate primary-root growth and lateral-root formation and increase root-hair elongation. Reception of strigolactones occurs via a specific cellular system which includes a D14-like/MAX2-like/SCF complex that, upon perception of strigolactone signalling, leads to certain degradation of receptors and ...
متن کاملNtann12 annexin expression is induced by auxin in tobacco roots
Ntann12, encoding a polypeptide homologous to annexins, was found previously to be induced upon infection of tobacco with the bacterium Rhodococcus fascians. In this study, Ntann12 is shown to bind negatively charged phospholipids in a Ca(2+)-dependent manner. In plants growing in light conditions, Ntann12 is principally expressed in roots and the corresponding protein was mainly immunolocalize...
متن کاملLateral auxin transport in stems and roots.
The lateral movement of auixin has been stuidied with bioassays and also by application of '4C-IAA. Both techniqutes have demonstrated that the tupper hal,f of a horizontally positioned stem or root contains at least 30 to 45 % of the total auxin present in the tissuie (2). However, such an auxin gradient is difficult to reconcile with the Cholodny-WVent theory of root geotropism becatuse it is...

پژوهش حاضر در چارچوب مکتب دستکاری قرار گرفت و با استفاده از تقسیم بندی دوکات (2007) از شیوه های دستکاری، به دنبال یافتن پاسخ برای پرسش های زیر بود: 1-رایج ترین شیوه دستکاری در دوبله فیلم ها کدام است؟ 2-رایج ترین شیوه دستکاری در زیرنویس فیلم ها کدام است؟ 3-دستکاری در دوبله فیلم ها رایج تر است یا در زیرنویس آن ها؟ این پژوهش از نوع تحقیقات توصیفی- مقایسه ای و پیکره ای می باشد. پیکره تحقیق شا...
Disturbed Local Auxin Homeostasis Enhances Cellular Anisotropy and Reveals Alternative Wiring of Auxin-ethylene Crosstalk in Brachypodium distachyon Seminal Roots
Observations gained from model organisms are essential, yet it remains unclear to which degree they are applicable to distant relatives. For example, in the dicotyledon Arabidopsis thaliana (Arabidopsis), auxin biosynthesis via indole-3-pyruvic acid (IPA) is essential for root development and requires redundant TRYPTOPHAN AMINOTRANSFERASE OF ARABIDOPSIS 1 (TAA1) and TAA1-RELATED (TAR) genes. A ...
