Plasmid-based one-pot saturation mutagenesis [PDF]

open access: yesNature Methods, 2016
Deep mutational scanning is a foundational tool for addressing the functional consequences of large numbers of mutants, but a more efficient and accessible method for construction of user-defined mutagenesis libraries is needed. Here we present nicking mutagenesis, a robust, single-day, one-pot saturation mutagenesis method performed on routinely ...

Modern High-Yielding Maize, Wheat and Soybean Cultivars in Response to Gypsum and Lime Application on No-Till Oxisol

open access: yesRevista Brasileira de Ciência do Solo, 2017
Modern maize, wheat, and soybean cultivars are usually characterized by a short cycle, high shoot-root ratio, and high responsiveness to nutrient input. Continuous no-tillage management (NTS) frequently leads to a steep gradient in soil chemical quality ...

Decidability Results for Saturation-Based Model Building [PDF]

open access: yes, 2009
Saturation-based calculi such as superposition can be successfully instantiated to decision procedures for many decidable fragments of first-order logic. In case of termination without generating an empty clause, a saturated clause set implicitly represents a minimal model for all clauses, based on the underlying term ordering of the superposition ...

Relationships between soil pH and base saturation – conclusions for Polish and international soil classifications

open access: yesSoil Science Annual, 2018
Taking into account the fact that (a) measurement of the cation exchange capacity and base saturation is practically unavailable in the field, that formally makes impossible the reliable field classification of many soils, (b) base saturation is measured

Mitigation of the Gradient of Chemical Properties in the Rooting Zone of Dystrophic Oxisols by Gypsum and Lime Inputs under a No-Till System

open access: yesRevista Brasileira de Ciência do Solo
Improvement of soil chemical properties in dystrophic Oxisols managed under long-term no-tillage system (NTS) with surface broadcast lime has been, frequently, restricted to a shallow topsoil layer.

Alterações químicas temporais nas faixas de adubação e entrelinhas do pomar, nutrição e produção de laranja após calagem superficial Yield and temporal chemical changes in fertilizer bands and inter-rows of an orange orchard after surface liming

open access: yesRevista Brasileira de Ciência do Solo, 2008
Apesar das diferenças químicas entre as faixas de adubação e entrelinhas de pomares de laranjeiras, o critério para a calagem superficial entre esses dois locais ainda é desconhecido.

Alterações nas propriedades químicas e físicas de um chernossolo com diferentes coberturas vegetais Alterations in the chemical and physical properties of a chernosol under different crop covers

open access: yesRevista Brasileira de Ciência do Solo, 2007
O agrossistema de Itapetinga, Bahia, tem a pecuária como uma das principais atividades econômicas. Sabe-se que a pecuária é uma atividade que causa impactos diretos no solo, no subsolo e na vegetação. Este estudo teve o objetivo de verificar mudanças nas

Soils classified in the Arboretum Mlyňany, Slovakia

open access: yesFolia Oecologica, 2018
Successful adaptation of introduced trees requires providing appropriate conditions for their growth and life. In this context, our study aim was a soil survey in the Arboretum Mlyňany, on the basis of which the soils could be classified.

Soil and Vegetation Drive Sesquiterpene Lactone Content and Profile in Arnica montana L. Flower Heads From Apuseni-Mountains, Romania

open access: yesFrontiers in Plant Science, 2022
Arnica montana L. (AM, Asteraceae) is a perennial, herbaceous vascular plant species of commercial importance. The flower heads’ pharmacological properties are attributed mainly to sesquiterpene lactones (SLs), with phenolic acids and flavonoids also ...

The effect of saturated pyrimidine bases on RNA conformation

open access: yesFEBS Letters, 1972
Saturation of the pyrimidine bases in polynucleotides leads to pronounced changes in their biological activity. The template activity of copolymers of 5,6-dihydrouridine and uridine decreases with increasing 5,6-dihydrouridine content in an in vitro protein synthesizing system [l] and changes its coding properties in an RNA-polymerase system [2 ...
