Variation in phytate accumulation in common bean (Phaseolus vulgaris L.) fruit explants

open access: yesBrazilian Archives of Biology and Technology, 2008
The in vitro synthesis of phytate was studied in common bean fruit explants. Different concentrations of sucrose; phosphorus (P); myo-inositol; abscisic acid (ABA); glutamine and methionine, were tested.

Impaired phloem loading in zmsweet13a,b,c sucrose transporter triple knock-out mutants in Zea mays.

open access: yesNew Phytologist, 2018
Crop yield depends on efficient allocation of sucrose from leaves to seeds. In Arabidopsis, phloem loading is mediated by a combination of SWEET sucrose effluxers and subsequent uptake by SUT1/SUC2 sucrose/H+ symporters.

Salt intake and regulation in two passerine nectar drinkers: white-bellied sunbirds and New Holland honeyeaters [PDF]

open access: yes, 2012
Avian nectarivores face the dilemma of having to conserve salts while consuming large volumes of a dilute, electrolyte-deficient diet. This study evaluates the responses to salt solutions and the regulation of salt intake in white-bellied sunbirds ...

Physiological model to estimate the maturity of sugarcane Modelo fisiológico para a estimativa da maturação em cana-de-açúcar

open access: yesScientia Agricola, 2009
Sugarcane (Saccharum spp.) grows in different weather and management conditions which directly affect crop maturation. These conditions lead to the necessity of quantifying crop response to different stimuli for planning purposes. Forecast models for the

Carbon source–sink relationship in Arabidopsis thaliana: the role of sucrose transporters

open access: yesPlanta, 2017
The regulation of source-to-sink sucrose transport is associated withAtSUC andAtSWEET sucrose transporters’ gene expression changes in plants grown hydroponically under different physiological conditions. Source-to-sink transport of sucrose is one of the

Using holographic microscopy to measure the effect of confinement on crowding agents in lipid vesicles [PDF]

open access: yes, 2023
The hydrodynamic effects of macromolecular crowding inside cells is often studied in vitro by using polymers as crowding reagents. Confinement of polymers inside cell-sized droplets has been shown to affect the diffusion of small molecules. Here we develop a method, based on digital holographic microscopy, to measure the diffusion of polystyrene ...

Pollen elicits proboscis extension but does not reinforce PER learning in honeybees [PDF]

open access: yes, 2013
The function of pollen as a reward for foraging bees is little understood, though there is evidence to suggest that it can reinforce associations with visual and olfactory floral cues.

Cotton fiber elongation requires the transcription factor GhMYB212 to regulate sucrose transportation into expanding fibers.

open access: yesNew Phytologist, 2019
Cotton is white gold across the globe and composed of fiber cells derived from the outer integument of cotton ovules. Fiber elongation uses sucrose as a direct carbon source.

Some nutritional properties of unrefined sugar and its promotion of the survival of new-born rats. [PDF]

open access: yes, 2005
1. The claims that rats fed on diets with ‘brown sugar’ (unrefined muscovado) perform better in a number of ways than do rats fed on refined white sugar (sucrose) have been examined. 2.

Mycorrhizas alter sucrose and proline metabolism in trifoliate orange exposed to drought stress

open access: yesScientific Reports, 2017
Arbuscular mycorrhizal fungi (AMF) can enhance drought tolerance in plants, whereas little is known regarding AMF contribution to sucrose and proline metabolisms under drought stress (DS). In this study, Funneliformis mosseae and Paraglomus occultum were
