Summary: The study characterized the plant growth-promoting traits of Enterobacter sp. FM-1 and its ability to promote growth, increase IAA, P, and Fe concentrations, and facilitate Cd and Pb phytoremediation in Centella asiatica L. The results showed that FM-1 secreted IAA, produced siderophores, and had P-solubilization ability, even under Cd exposure. Pot experiments confirmed that FM-1 successfully colonized the roots of C. asiatica L., reducing soil pH and increasing bioavailability of Cd and Pb.

Summary: Auxins are phytohormones that regulate plant growth and development, primarily through the action of indole-3-acetic acid (IAA). The levels of free IAA in plants are controlled by oxidative catabolism and conjugation reactions. In this study, two new auxin metabolites, oxIAA-leucine and oxIAA-phenylalanine, were identified and characterized in plants. A new method using liquid chromatography-tandem mass spectrometry was developed to quantify a wide range of IAA metabolites. The distribution of various auxin metabolites varied among plant species and plant sections, indicating diverse inactivation pathways of auxin among angiosperm plants. These findings contribute to a better understanding of IAA homeostasis.

Summary: The combination of the two mutations is not sufficient to fully prevent the conversion of IAM to IAA, and the detected strong accumulation of IAM significantly impairs seed development. Genome-wide expression studies reveal that the double mutant is broadly affected in its translational capacity, with a small number of plant growth regulating transcriptional circuits being repressed by the high IAM content in the seed.

Summary: The researchers report an activatable antimicrobial nanoplatform with ultralow-background persistent luminescent (PL) turn-on imaging and therapeutic capability. The platform utilizes chitosan as a linker to immobilize copper ions on the surface of persistent luminescent nanoparticles (PLNPs) to fabricate PLNPs-CS-Cu2+. The PL emission of PLNPs is quenched by Cu2+ under physiological conditions but recovered due to the conversion of Cu2+ into Cu+ by high glutathione (GSH) levels at the infection site. The as-prepared antibacterial nanoplatform shows promise for highly sensitive persistent luminescent imaging and simultaneous treatment of bacterial infection.
