The effects of Group 11 transition metals including

Effects of Group 11 transition metals on saturable ethylene binding in yeast cell membranes containing the Arabidopsis ETR1 receptor. Membranes isolated from yeast expressing the fulllength ETR1 receptor were incubated with CuSO 4, AgNO 3, or AuCl 3 at the indicated concentrations. For comparison, saturable ethylene binding in the presence of varying concentrations of CoS0 4 is shown.

PROTEIN S ACYL TRANSFERASE10 Is Critical for

Protein S acylation, commonly known as palmitoylation, is a reversible posttranslational modification that catalyzes the addition of a saturated lipid group, often palmitate, to the sulfhydryl group of a Cys. Palmitoylation regulates enzyme activity, protein stability, subcellular localization, and intracellular sorting. Many plant proteins are palmitoylated.

Populus euphratica APYRASE2 Enhances Cold

Apyrase and extracellular ATP play crucial roles in mediating plant growth and defense responses. In the coldtolerant poplar, Populus euphratica , low temperatures upregulate APYRASE2 PeAPY2 expression in callus cells. We investigated the biochemical characteristics of PeAPY2 and its role in cold tolerance. We found that PeAPY2 predominantly localized to the plasma membrane, but punctate ...

Natural Variation of Root Traits From Development to

The root system has a crucial role for plant growth and productivity. Due to the challenges of heterogeneous soil environments, diverse environmental signals are integrated into root developmental decisions. While root growth and growth responses are genetically determined, there is substantial natural variation for these traits. Studying the genetic basis of the natural variation of root ...

Round shape gold nanoparticles effect of particle size

Nowadays, due to a wide range of applications of nanoparticles NPs in many industrial areas, accumulations of those entities in environment pose a great risk. Owing to their inertness, noble metal NPs may remain in contaminated soils nearly unchanged for long time. Within this context, size, shape, and concentrationdependent uptake of particles by plants belongs to unexplored area.

Abstract. The Arabidopsis thaliana genome contains 20 cyclic nucleotide gated channel CNGC genes encoding putative nonselective ion channels.Classical and reverse genetic approaches have revealed that two members of this family CNGC2 and CNGC4 play a role in plant defence responses whereas CNGC1 and CNGC10 may participate in heavy metal and cation transport.
