Regionally distinct elongation responses to water stress in the maize primary root tip have been observed in the past. A genetic basis for such differential responses has been demonstrated. Normalized bar-coded cDNA libraries were generated for four regions of the root tip, 0-3 mm (R1), 3-7 mm (R2), 7-12 mm (R3), and 12-20 mm (R4) from the root apex, and transcript profiles for these regions we...
Mitigating the effects of changing climate with adaptable cultivars while reducing input burden additional selection criteria is becoming a priority, especially as water shortage limiting soybean production in Europe. To evaluate functionality photosynthetic apparatus drought, chlorophyll (Chl a) fluorescence was measured 16 elite lines drought and conditions sufficient supply V2 (second node),...
BACKGROUND & OBJECTIVES R proteins were first identified by Lancefield in group B Streptococcus (GBS) as resistant to trypsin at pH8 and sensitive to pepsin at pH2. The R4 protein found predominantly in type III and some type II and V invasive isolates conforms to these criteria. The Rib protein, although structurally and epidemiologically similar to R4, was reported as resistant to both protea...
BACKGROUND TRAIL/Apo2L is a pro-apoptotic ligand of the TNF family that engages the apoptotic machinery through two pro-apoptotic receptors, TRAIL-R1 and TRAIL-R2. This cell death program is tightly controlled by two antagonistic receptors, TRAIL-R3 and TRAIL-R4, both devoid of a functional death domain, an intracellular region of the receptor, required for the recruitment and the activation of...
Glyphosate has been the most intensely herbicide used worldwide for decades, and continues to be a single tool for controlling weeds in woody crops. However, the adoption of this herbicide in a wide range of culture systems has led to the emergence of resistant weeds. Glyphosate has been widely used primarily on citrus in the Caribbean area, but a study of resistance in the Caribbean islands of...
The current study aimed to evaluate the impact of charcoal grilling in generation various polycyclic aromatic hydrocarbons tissues 5 different organs (leg, chest, wings, liver, and heart) falcated ducks ( Mareca falcata) before after pasting them with condiment recipes (R1, R2, R3, R4). All condiment-pasted control samples before/after were pursued RP-HPLC for quantification unknown PAHs. Tissu...
تعادل بین ورودی و خروجی کربن نقش بسزایی در پایداری بوم نظام های زراعی، گرمایش جهانی و تغییر اقلیم دارد. به منظور ارزیابی خصوصیات فیزیکی، شیمیایی و پتانسیل ترسیب کربن تحت تأثیر شدت های مختلف خاک ورزی، نوع تناوب زراعی و مدیریت بقایای گیاهی آزمایشی به صورت کرت های نواری در قالب طرح بلوک های کامل تصادفی با سه تکرار در مزرعه تحقیقاتی دانشکده کشاورزی دانشگاه فردوسی مشهد در دو سال زراعی 90-1389 و 91-1...
Stumps account for a large proportion of coarse woody debris in managed forests, but their decay dynamics are poorly understood. The loss of mass and the degree of humification of the above-ground woody debris, below-ground woody debris, bark and root system (R1, 10 mm ≥ diameter > 0 mm; R2, 25 mm ≥ diameter >10 mm; 100 mm ≥ R3 > 25 mm; R4 > 100 mm) of Masson pine (Pinus massoniana) stump syste...
In the Non-Hodgkin Lymphoma-Berlin-Frankfurt-Münster 95 (NHL-BFM95) study, we tested by randomization whether for patients with B-cell neoplasms methotrexate as intravenous infusion over 4 hours (MTX-4h) is not inferior to, but less toxic than, a 24-hour intravenous infusion (MTX-24h). Second, we investigated against the historical control of study NHL-BFM90, whether for patients with moderate ...
We construct the linear differential equations of third order satisfied by the classical 2orthogonal polynomials. We show that these differential equations have the following form: R4,n(x)P (3) n+3(x)+R3,n(x)P ′′ n+3(x)+R2,n(x)P ′ n+3(x)+R1,n(x)Pn+3(x)=0, where the coefficients {Rk,n(x)}k=1,4 are polynomials whose degrees are, respectively, less than or equal to 4, 3, 2, and 1. We also show tha...
