Stomatal frequency and gas exchange differs in two Blechnum species (Pteridophyta, Blechnaceae) with contrasting ecological breadth La frecuencia estomática e intercambio de gases difieren en dos especies de Blechnum (Pteridophyta, Blechnaceae) con distinto rango ecológico

open access: yesGayana: Botanica, 2012
In Chilean temperate forest, the fern Blechnum chilense has a wide ecological breath, but occur mainly in full sun habitats, while Blechnum mochaenum is restricted only to shady sites.

Analysis of stomatal characteristics of maize hybrids and their parental inbred lines during critical reproductive periods

open access: yesFrontiers in Plant Science
The stomatal phenotype is a crucial microscopic characteristic of the leaf surface, and modulating the stomata of maize leaves can enhance photosynthetic carbon assimilation and water use efficiency, thereby playing a vital role in maize yield formation.

Plant hydraulic traits reveal islands as refugia from worsening drought. [PDF]

open access: yes, 2020
Relatively mesic environments within arid regions may be important conservation targets as 'climate change refugia' for species persistence in the face of worsening drought conditions.

Trade-offs Between Water Transport Capacity and Drought Resistance in Neotropical Canopy Liana and Tree Species [PDF]

open access: yes, 2016
In tropical forest canopies, it is critical for upper shoots to efficiently provide water to leaves for physiological function while safely preventing loss of hydraulic conductivity due to cavitation during periods of soil water deficit or high ...

Enabling the study of gene function in gymnosperms: Virus‐induced gene silencing in Ephedra tweedieana

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise As the sister clade to angiosperms, extant gymnosperms are crucial for reconstructing ancestral gene regulatory networks in seed plants. This highlights the need for model systems representing each of their distinct lineages. However, tools to quickly and effectively investigate gene function in gymnosperms are still limited due to the

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.

Effects of Ground Level Ozone on Vegetation [PDF]

open access: yes, 2010
All the experiments conducted in this project use ozone exposures that either are already currently occurring or are expected to occur over UK uplands this century, if predictions of increasing „background‟ ozone exposure are correct.

QTL analysis for stomatal density and size in wheat spike organ

open access: yesEmirates Journal of Food and Agriculture, 2018
Plant changes its own photosynthetic rate and transpiration rate through regulating stomatal aperture, stomatal density and stomatal distribution. In this study, stomatal density, length and width of wheat spike organs, including palea, lemma and glume, at the third day after flowering were investigated, using a wheat doubled haploid population from a ...

Radiologic, Histologic and Scanning Electron Microscopic Characterization of the Peritoneal Reflection in Crohn's Disease

open access: yesClinical Anatomy, EarlyView.
ABSTRACT The peritoneal reflection bridges visceral and parietal peritoneum and lacks adjoining or underlying organs. As such it provides an opportunity to perform a focussed examination of the peritoneum in Crohn's disease. The aim of this study was to exploit this anatomical property and conduct a multilayered, focussed examination of the peritoneal ...
