Functional imaging of plants: A nuclear magnetic resonance study of a cucumber plant

open access: yes, 2002
Functional magnetic resonance imaging was used to study transients of biophysical parameters in a cucumber plant in response to environmental changes. Detailed flow imaging experiments showed the location of xylem and phloem in the stem and the response ...

The social life of money for children

open access: yesThe British Journal of Sociology, EarlyView.
Abstract Inspired by Nigel Dodd's The Social Life of Money, this article proposes an analysis of entangled economic lives, that is, how meaning, structures and politics jointly shape the flow of monies within households. The past decades have marked a shift from “childrearing expenditures” to “parenting investments” that align with new visions of both ...

The impact of prolonged drought on phloem anatomy and phloem transport in young beech trees

open access: yes, 2018
Phloem failure has recently been recognized as one of the mechanisms causing tree mortality under drought, though direct evidence is still lacking.We combined 13C pulse-labelling of 8-year-old beech trees (Fagus sylvatica L.) growing outdoors in a ...

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

open access: yesInsect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

Hemipteran vectors of stylet‐borne plant viruses: Aphids lead the charge

open access: yesInsect Science, EarlyView.
Among all sap‐feeding hemipterans, aphids stand out by far as the most important vectors of noncirculative plant viruses. Compared to whiteflies and mealybugs, aphids’ highly specialized stylet anatomy and distinct feeding behaviors contribute, together with other features of their biology, to their remarkable efficiency in transmitting stylet‐borne ...

Phloem development: current knowledge and future perspectives.

open access: yes, 2014
Phloem, as a major tissue mediating long-distance communication, has been an object of extensive research ever since its structure was first reported in 1837. Functional phloem consists of sieve elements (SEs) and companion cells (CCs).

LsFAMeT and LsJHAMT coordinate JH biosynthesis to regulate fecundity in Laodelphax striatellus

open access: yesInsect Science, EarlyView.
The small brown planthopper (SBPH), Laodelphax striatellus, can trigger large‐scale outbreaks when encountering suitable habitats during migration due to their strong reproductive ability. This study investigated the role of juvenile hormone (JH) in regulating SBPH reproduction.

Effect of phloem interruption on leaf senescence and nutrient redistribution in wheat (Triticum aestivum)

open access: yes, 1990
The phloem of field-grown wheat was interrupted shortly after anthesis by steam-girdling below the ear or below one of the 2 uppermost leaf nodes. Senescence and nutrient remobilisation was delayed in leaves without phloem connection to the ear.

Attraction of Phoracantha mastersi (Coloeptera: Cerambycidae) to copulation‐associated olfactory stimuli

open access: yesAgricultural and Forest Entomology, EarlyView.
Damage caused by Phoracantha mastersi larvae are the primary cause of forest decline in Australia's subalpine forests. Behaviour of male adult beetles was tested in response to a suite of commercial semiochemicals and conspecifics engaged in active copulation within a Y‐maze.
