Studies on the Phloem of the Dicotyledons. I. Phloem of the Juglandaceae [PDF]

open access: yesBotanical Gazette, 1911
The six species of the Juglandaceae which have been considered possess well developed lateral sieve plates which have the same structure and appearance and seem to function in the same manner as the sieve plates on the end walls. The callus on the lateral sieve plates is identical in character with that on the end walls.

Not All Agreements Are Equal: Heterogeneous Effects of RTAs on Latin American Agri‐Food Exports, 1990–2019

open access: yesAgribusiness, EarlyView.
ABSTRACT Since the final decade of the 20th century, Latin American countries have increasingly regarded the signing of regional trade agreements (RTAs) as a promising strategy for expanding their exports. Within this context, the main objective of this study is to assess the impact of RTAs on agri‐food exports in Latin America over the period 1990 ...

Real‐time monitoring of root dielectric properties for assessing crop plant damage caused by foliar application of glyphosate

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise There is a knowledge gap regarding how foliar injury and restricted water uptake can be detected by measuring root dielectric response. This pot study nondestructively evaluated the efficiency of real‐time dielectric measurement to monitor the effects of glyphosate spraying.

Atypical Attentional Effort During Visual Search in Autistic Adults: Evidence From Task‐Evoked Pupillary Responses

open access: yesAutism Research, EarlyView.
ABSTRACT According to prevalent views, autistic individuals have a stronger tendency to allocate attention to details, as supported by reports of enhanced visual search performance. However, both the dynamics and the types of information involved in attentional guidance in autism are not fully understood.

Surface hydration‐induced damage in tight oil‐bearing sandy conglomerate reservoirs

open access: yesDeep Underground Science and Engineering, EarlyView.
A series of techniques such as X‐ray diffraction, scanning electron microscopy, energy‐dispersive spectroscopy, conductivity tests, and infrared thermal imaging were used. The key findings are the identification of a two‐stage surface hydration process and the elucidation of the effects of various minerals and elements on the hydration process ...

Unraveling the Host Plant Alternation of Cacopsylla pruni – Adults but Not Nymphs Can Survive on Conifers Due to Phloem/Xylem Composition

open access: yesFrontiers in Plant Science, 2018
Plant sap feeding insects like psyllids are known to be vectors of phloem dwelling bacteria (‘Candidatus Phytoplasma’ and ‘Ca. Liberibacter’), plant pathogens which cause severe diseases and economically important crop damage.

A Review: Systemic Signaling in the Regulation of Plant Responses to Low N, P and Fe

open access: yesPlants, 2023
Plant signal transduction occurs in response to nutrient element deficiency in plant vascular tissue. Recent works have shown that the vascular tissue is a central regulator in plant growth and development by transporting both essential nutritional and ...

What Is Phloem Unloading? [PDF]

open access: yesPlant Physiology, 1990
Several studies of phloem unloading have failed to distinguish between transport events occurring at the sieve element/companion cell boundary and subsequent short-distance transport through parenchyma cells. Indirect evidence has been obtained for symplastic unloading in storage and utilization sinks. In other sinks transfer to the apoplast may occur,

Facilitating the timely diagnosis of Lennox–Gastaut syndrome: A checklist to support clinical practice

open access: yesEpileptic Disorders, EarlyView.
Abstract Objective To develop and evaluate a simple‐to‐use checklist to support physicians with the timely diagnosis of Lennox–Gastaut syndrome (LGS). Methods A panel of 10 pediatric and adult epileptologists used the International League Against Epilepsy (ILAE) criteria for LGS classification and definition to develop seven questions for the checklist,

Comparison of volume‐ and surface‐based magnetic resonance imaging morphometry algorithms in the detection of focal cortical dysplasia

open access: yesEpilepsia, EarlyView.
Abstract Objective Detection of focal cortical dysplasia (FCD) remains a major challenge in presurgical epilepsy diagnostics. Magnetic resonance imaging (MRI) morphometry increasingly improves lesion detection and postsurgical outcomes. The volume‐based Morphometric Analysis Program, version 2018 (MAP18) with integrated artificial neural network and ...
