The initiation of flowering in Arabidopsis is retarded or abolished by environmental stresses. Focusing on salt stress, we provide a molecular explanation for this well-known fact. A protein complex consisting of GI, a clock component important for flowering and SOS2, a kinase activating the [Na(+)] antiporter SOS1, exists under no stress conditions. GI prevents SOS2 from activating SOS1. In th...
هدف از پژوهش حاضر، بررسی تأثیر قارچهای میکوریز بر رشد (ارتفاع، قطر یقه، حجم ریشه، طول ریشه)، بیومس (وزن تر و خشک ریشه و اندام هوایی) و جذب عناصر (نیتروژن، فسفر، پتاسیم در ریشه و اندام هوایی) در گونه ارغوان (Cercis griffithii) بود. برای این منظور در شرایط گلخانهای تأثیر سه نوع قارچ Glomus mosseae، G. intraradices و Gigaspora gigantea به همراه شاهد، به مدت 8 ماه ارزیابی شد. نتایج تحقیق نشان داد...
BACKGROUND Ecological replacement involves the introduction of non-native species to habitats beyond their historical range, a factor identified as increasing the risk of failure for translocations. Yet the effectiveness and success of ecological replacement rely in part on the ability of translocatees to adapt, survive and potentially reproduce in a novel environment. We discuss the welfare as...
Drimia is a heterogeneous, poorly understood genus that requires major rearrangement. Chromosome behavior of gigantea and viridula; two species in D. altissima complex was studied for karyotypes transmission extra chromosomes pair pollen viability. Meristematic cells at the root tips viridula were by conventional cytogenetic karyotype analysis. numbers 2n = 22 20 viridula, respectively. Extra c...
calotropis gigantea (linn) and amoora rohituka (roxb.) have long been used in folkloric medicine for the treatment of various ailments in bangladesh. the present study was designed to investigate the cytotoxicity of isolated compounds from these two plants. two compounds, named β-boswellic acid (compound-1) and 2-methoxy-14-calamenenone (compound-2) were isolated from the flowers of calotropis ...
