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...
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...

The extraction of biomass and nutrients out of the forest is implicit to every harvest operation. In cable yarding, whole-tree harvesting (WTH) has become more prevalent in the last few decades and processing takes place at the roadside. There is a concern that WTH impairs site productivity due to nutrient removal. One option to increase the amount of biomass remaining in the stand is to top th...
Overcroping, shading and short growing season can reduce the pool of carbohydrate reserves, and consequently reduce the quality of crop in grapevines. An experiment was conducted in order to study the effects of cluster number and different levels of cane topping on balanced yield and qualitative traits of table grape (Vitis vinifera L.) cv. Askari. The design of experiment was factorial in com...

The nuclear protein kinase ATR is a key regulator of genome integrity that functions at checkpoints for damaged or incompletely replicated DNA. In this issue of Cell, Kumagai et al. (2006) shed light on the molecular mechanism that controls ATR. They report that a physical interaction between ATR and a distinct domain of TopBP1 greatly enhances ATR kinase activity.
The interaction between noncoding endogenous target mimicry (eTM) and its corresponding microRNA (miRNA) is a newly discovered regulatory mechanism and plays pivotal roles in various biological processes in plants. Tobacco (Nicotiana tabacum) is a model plant for studying secondary metabolite alkaloids, of which nicotine accounts for approximately 90%. In this work, we identified four unique to...
Over 124,300 heat pipes were installed in vertical support members on the Trans Alaska Pipeline System. Infrared surveys in the early 1980s revealed cold topping on some of these heat pipes. The cold topping was due to an accumulation of non-condensable gases, a by-product of corrosion or chemical dissociation of anhydrous ammonia. In 2000, Alyeska Pipeline Service Company undertook an experime...
