COMPORTAMENTO DAS SEMENTES DE SOJA DURANTE A FASE INICIAL DO PROCESSO DE GERMINAÇÃO

open access: yesScientia Agricola, 1997
Com o objetivo de avaliar o comportamento das sementes de soja durante a fase inicial do processo de germinação, utilizaram-se sementes de um lote de soja [Glycine max (L.) Merrill], do cultivar IAC-15, que foram submetidas ao envelhecimento artificial ...

Linear root water uptake by vegetation [PDF]

open access: yes, 2009
The performance of a simple model with a linear root water extraction term that varies with time is presented in this paper. The research is based on the use of a one-dimensional form of Richard’s Equation for unsaturated moisture flow including a sink ...

Water uptake by trees in a riparian hardwood forest (Rhine floodplain, France) [PDF]

open access: yes, 2008
Water flow in the soil–root–stem system was studied in a flooded riparian hardwood forest in the upper Rhine floodplain. The study was undertaken to identify the vertical distribution of water uptake by trees in a system where the groundwater is at a ...

How Does Silicon Mediate Plant Water Uptake and Loss Under Water Deficiency?

open access: yesFrontiers in Plant Science, 2018
In plants, water deficiency can result from a deficit of water from the soil, an obstacle to the uptake of water or the excess water loss; in these cases, the similar consequence is the limitation of plant growth and crop yield.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Aggressive prostate cancer is associated with pericyte dysfunction

open access: yesMolecular Oncology, EarlyView.
Tumor‐produced TGF‐β drives pericyte dysfunction in prostate cancer. This dysfunction is characterized by downregulation of some canonical pericyte markers (i.e., DES, CSPG4, and ACTA2) while maintaining the expression of others (i.e., PDGFRB, NOTCH3, and RGS5).

Bioavailability of pesticides in freshwater sediments [PDF]

open access: yes, 2007
In ecological risk assessment standardized sediment toxicity tests are used to predict the hazard of chemicals for sediment-living organisms. Feeding is a prerequisite in these long-term tests to avoid starvation of test organisms.

Monitoring of water from the underground to the tree: first results with a new sap extractor on a riparian woodland [PDF]

open access: yes, 2002
Riparian woodlands are characterized by variable hydrological conditions. Following the mapping of the complex underground water circulation of the wetlands, we studied the water uptake by trees.

Detection of circulating tumor DNA in colorectal cancer patients using a methylation‐specific droplet digital PCR multiplex

open access: yesMolecular Oncology, EarlyView.
We developed a cost‐effective methylation‐specific droplet digital PCR multiplex assay containing tissue‐conserved and tumor‐specific methylation markers. The assay can detect circulating tumor DNA with high accuracy in patients with localized and metastatic colorectal cancer.

Sonication of seeds increase germination performance of sesame under low temperature stress

open access: yesActa Agriculturae Slovenica, 2015
A laboratory experiment was conducted to determine the effect of ultrasound (US) exposure time on germination behavior of sesame seeds. All tests were carried out at 20 kHz in a water bath ultrasonic device varying two factors, treatment duration (10, 20
