BACKGROUND Topping is an important cultivating measure for flue-cured tobacco, and many genes had been found to be differentially expressed in response to topping. But it is still unclear how these genes are regulated. MiRNAs play a critical role in post-transcriptional gene regulation, so we sequenced two sRNA libraries from tobacco roots before and after topping, with a view to exploring tran...

In this study, a boil-off gas reliquefaction system that is part of liquid ethylene (LEG) carriers evaluated. The formed by two thermally interconnected two-stage refrigeration cycles. working fluid the bottoming cycle ethylene; topping propylene. research based on determining irreversibilities in cycles using entropy-cycle method thermodynamic analysis. impact process performance main componen...

A field experiment was conducted at the experimental of Department Horticulture in Sylhet Agricultural University to evaluate growth and yield performance three okra genotypes (viz. BARI Dherosh-1, Dherosh-2 & RAJ F1) under special management practices de-topping non de-topping) from March July 2022. The two factor laid out a Randomized Complete Block Design (RCBD) with replications. Dheros...

The "topping-off" technique is a new concept applying dynamic or less rigid fixation such as hybrid stabilization device (HSD) or interspinous process device (IPD) for the purpose of avoiding adjacent segment disease (ASD) proximal to the fusion construct. A systematic review of the literature was performed on the effect of topping-off techniques to prevent or decrease the occurrence of ASD aft...

topping stage of tobacco is a key time for development of agriculture measures to promote the quality of leaves. in order to investigating influence of topping timing and suckericide content on tobacco leaf, a factorial experiment on the basis of rcb design with 3 replications was conducted in 2011 at the tobacco research farm of isfahan. treatments were including topping time (t1: topping at e...

Double-strand breaks (DSBs) threaten chromosome integrity. The most accurate repair of DSBs is by homologous recombination (HR), catalyzed by recombination proteins such as Rad51. Three papers in this issue of Molecular Cell (Fasching et al., 2015; Kaur et al., 2015; Tang et al., 2015) now reveal the role of three of these proteins in budding yeast: Sgs1 (BLM homolog), Top3 (TOPIIIα homolog), a...

One of the most important practices in flue-cured tobacco farming is topping and sucker control at the right time. Topping cause's development and root growth, drought tolerance, reduce deployment pests, increased synthesis of nicotine. This study was conducted in randomized complete block design (RCBD) with 10 treatments in 3 replications over two years (2008-2009) at Tirtash research and educ...
