Auxins action on Glycine max secretory phospholipase A2 is mediated by the interfacial properties imposed by the phytohormones.

Numai utilizatorii înregistrați pot traduce articole

Secretory phospholipase A2 (sPLA2) are soluble enzymes that catalyze the conversion of phospholipids to lysophospholipids and free fatty acids at membrane interfaces. The effect of IAA and IPA auxins over the activity of recombinant sPLA2 isoforms from Glycine max was studied using membrane model

Genome-wide identification and expression analysis of dormancy-associated gene 1/auxin repressed protein (DRM1/ARP) gene family in Glycine max.

Numai utilizatorii înregistrați pot traduce articole

Dormancy-Associated gene 1/Auxin Repressed protein (DRM1/ARP) genes are responsive to hormones involved in defense response to biotic stress, such as salicylic acid (SA) and methyl jasmonate (MeJA), as well as to hormones that regulate plant growth and development, including auxins. These

Comprehensive Analysis of the Soybean (Glycine max) GmLAX Auxin Transporter Gene Family.

Numai utilizatorii înregistrați pot traduce articole

The phytohormone auxin plays a critical role in regulation of plant growth and development as well as plant responses to abiotic stresses. This is mainly achieved through its uneven distribution in plant via a polar auxin transport process. Auxin transporters are major players in polar auxin

Genome-wide analysis and expression profiling of the PIN auxin transporter gene family in soybean (Glycine max).

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND The plant phytohormone auxin controls many aspects of plant growth and development, which largely depends on its uneven distribution in plant tissues. Transmembrane proteins of the PIN family are auxin efflux facilitators. They play a key role in polar auxin transport and are associated

Auxin-regulated Wall Loosening and Sustained Growth in Elongation.

Numai utilizatorii înregistrați pot traduce articole

It is proposed that auxin regulates and coordinates both wall loosening and the supply of wall materials in elongation. The tenets of the proposal allowed testable predictions. It was determined that, if the cell walls of Glycine max L. var. Wayne hypocotyl segments are maintained in a loosened

Azido auxins : photolysis in solution and covalent binding to soybean.

Numai utilizatorii înregistrați pot traduce articole

The potential of three auxin analogs, 4-, 5-, and 6-azidoindole-3-acetic (4-N(3)IAA, 5-N(3)IAA, and 6-N(3)IAA), as photoaffinity labeling agents for the detection and isolation of auxin receptors was assessed by irradiating these compounds at 365 nm on TLC plates, in solution, and in contact with

Auxin Transport in Suspension-Cultured Soybean Root Cells : II. Anion Effects on Carrier-Mediated Uptake.

Numai utilizatorii înregistrați pot traduce articole

To test the hypothesis that the carrier-mediated component of the indoleacetic acid (IAA) influx involves an electrogenic proton/IAA anion symport, the effects on the IAA influx of salts expected to depolarize the membrane potential were examined in suspension-cultured soybean (Glycine max [L.]

Ultrastructural alteration of plant plasma membranes induced by auxin and calcium ions.

Numai utilizatorii înregistrați pot traduce articole

Ultrastructural changes in isolated and in situ plasma membranes of etiolated soybean hypocotyls (Glycine max L. cv. Wayne) were induced by indole-3-acetic acid (IAA), other auxins, and calcium chloride. Fixed and embedded preparations were stained by a phosphotungstate-chromate procedure to

Oligogalacturonides inhibit the induction of late but not of early auxin-responsive genes in tobacco.

Numai utilizatorii înregistrați pot traduce articole

Oligogalacturonides (OGs) released from the plant cell wall regulate several defense responses, as well as various aspects of plant growth and development. In these latter effects, OGs exhibit auxin-antagonist activity. To shed light on the mechanism by which OGs antagonise auxin, we analysed the

Transcriptomic signature reveals mechanism of flower bud distortion in witches'-broom disease of soybean (Glycine max).

Numai utilizatorii înregistrați pot traduce articole

Soybean (Glycine max L. Merril) crop is major source of edible oil and protein for human and animals besides its various industrial uses including biofuels. Phytoplasma induced floral bud distortion syndrome (FBD), also known as witches' broom syndrome (WBS) has been one of the major

Auxin transport: a new synthetic inhibitor.

The new synthetic plant growth regulator DPX1840 (3,3a-dihydro-2-(p-methoxyphenyl)-8H-pyrazolo [5,1-a] isoindol-8-one) was examined for its effects on auxin transport. At a concentration of 0.5 mm in the receiver agar cylinders DPX1840 significantly inhibited the basipetal transport of

A G-Box-Binding Protein from Soybean Binds to the E1 Auxin-Response Element in the Soybean GH3 Promoter and Contains a Proline-Rich Repression Domain.

Numai utilizatorii înregistrați pot traduce articole

The E1 promoter fragment (-249 to -203) is one of three auxin-response elements (AuxREs) in the soybean (Glycine max L.) GH3 promoter (Z.-B. Liu, T. Ulmasov, X. Shi, G. Hagen, T.J. Guilfoyle [1994] Plant Cell 6: 645-657). Results presented here further characterize and delimit the AuxRE within the

Effects of exogenous auxins on expression of lipoxygenases in cultured soybean embryos.

Numai utilizatorii înregistrați pot traduce articole

The expression of lipoxygenases (LOXs) is known to be developmentally regulated in soybeans (Glycine max. [L.] Merr.). Hormones have been firmly established as being involved in the growth and developmental processes of a number of plant species. Correlation between the expression of LOXs and the

Soybean somatic embryogenesis: interactions between sucrose and auxin.

Numai utilizatorii înregistrați pot traduce articole

The interaction between sucrose and auxin in soybean (Glycine max L. Merr.) somatic embryogenesis was investigated by culturing immature cotyledon explants on factorial combinations of NAA (6.25, 12.5, 25 and 50 mg/l) and sucrose (0.5, 1, 2 and 4%). A significant interaction between sugar and auxin

A rapid response to a plant hormone: auxin stimulates phospholipase A2 in vivo and in vitro.

Addition of the active auxins indole-3-acetic acid, 2,4-dichlorophenoxyacetic acid or alpha-naphthylacetic acid to cultured soybean (Glycine max L.) cells prelabeled with ethanolamine or choline increased the radioactivity in the lysophosphatidylethanolamine (LPE) or lysophosphatidylcholine (LPC)
