Spatial Distribution of Soil Macroelements, Their Uptake by Plants, and Green Pea Yield under Strip-Till Technology

open access: yesAgronomy
Using conservation tillage to grow crops that enhance soil quality, such as legumes, seems to be one of the best solutions for sustainable agriculture. The field study was conducted to identify the effect of soil cultivation technology and fertilization,

Shoot-Look-Shoot: A Review and Extension

open access: yesOperations Research, 2004
We consider the optimal use of information in shooting at a collection of targets, generally with the object of maximizing the average number (or value) of targets killed. The shooting problem is viewed as a Markov decision process, and the modal solution technique is stochastic dynamic programming.

Differential Shoot Feeding by Adult \u3ci\u3eTomicus Piniperda\u3c/i\u3e (Coleoptera: Scolytidae) in Mixed Stands of Native and Introduced Pines in Indiana. [PDF]

open access: yes, 2017
The larger pine shoot beetle Tomicus piniperda, a native bark beetle of Europe and Asia, was found in North American Christmas tree plantations in 1992 in Ohio. Subsequent surveys found it in six U.S. states and in one Canadian province.

Coppice potential of 16 different species of Eucalyptus after an eight-year rotation [PDF]

open access: yes, 2019
The adoption of coppice is a commonly used management in different regions of Brazil for plantations of Eucalyptus, which requires less investments. However, there are variations in the ability of each genotype to emit sprouts, and higher yields can be ...

Heavy metals phyto-assessment in commonly grown vegetables: water spinach (I. aquatica) and okra (A. esculentus) [PDF]

open access: yes, 2016
The growth response, metal tolerance and phytoaccumulation properties of water spinach (Ipomoea aquatica) and okra (Abelmoschus esculentus) were assessed under different contaminated spiked metals: control, 50 mg Pb/kg soil, 50 mg Zn/kg soil and 50 mg Cu/

An intracellular transporter mitigates the CO2‐induced decline in iron content in Arabidopsis shoots

open access: yesFEBS Letters, EarlyView.
This study identifies a gene encoding a transmembrane protein, MIC, which contributes to the reduction of shoot Fe content observed in plants under elevated CO2. MIC is a putative Fe transporter localized to the Golgi and endosomal compartments. Its post‐translational regulation in roots may represent a potential target for improving plant nutrition ...

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

open access: yesFEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Adventitious shoot propagation and cultural inputs in nursery production of a primocane-fruiting blackberry selection [PDF]

open access: yes, 2006
Studies were conducted from January to October 2005 to determine the effect of root-cutting length on adventitious shoot yield and the management practices necessary to produce nurseryquality primocane-fruiting blackberry plants. The first portion of the
