Microbial rhodopsins are photoreceptor proteins that utilize light to elicit various biological functions. The best-studied microbial outward proton (H+)-pumping rhodopsins, which transport H+ from the cytoplasmic extracellular side. Recently, weak organic acid (WOA) effect, specifically enhancement of pumping activity by WOAs such as acetic and indole-3-acetic (IAA), was discovered in H+-pumping fungi. However, it remains unclear whether WOA effect exists nonfungal rhodopsins. Here, we revealed a bacterial pump rhodopsin, PspR, rhizobacterium Pseudomonas putida, is also enhanced IAA. Using transient absorption measurements on purified PspR protein, found accelerate uptake release protonated counterion during its photocycle. Furthermore, applied side has an inhibitory less significant for IAA can be mitigated increasing concentration or introducing donor residue. These findings rhodopsin provide new insights into physiological function bacteria, particularly their interaction with plants.

Climate-induced drought impacts plant growth and development. Recurring droughts increase the demand for water food production landscaping. Native plants in Intermountain West region of US are keen interest low use landscaping as they acclimatized to dry cold environments. These native do very well at their locations but difficult propagate landscape. One possible reasons is lack associated microbiome Microbiome soil contributes health Here, we used bulk from Ceanothus velutinus (snowbrush ceanothus) inoculant enhance its propagation. Snowbrush ceanothus an ornamental low-water that hard asexually. Using 50% potting mix significantly improved survival rate cuttings compared no-treated cuttings. Twenty-four growth-promoting rhizobacteria (PGPR) producing indole acetic acid (IAA) were isolated rhizosphere roots survived snowbrush. Seventeen isolates had more than 10µg/mL IAA shortlisted tested seven different (PGP) traits; 76% showed nitrogen-fixing ability on Norris Glucose Nitrogen free media,70% phosphate solubilization activity, siderophore production, 36% protease 94% ACC deaminase activity DF-ACC media, produced catalase all ammonia.

Wastewater contains various emerging contaminants, including heavy metals, residues of pesticides, and pharmaceuticals. Therefore, irrigation with wastewater can enhance metal contamination in soil adversely affect plant growth. To mitigate this problem, growth-promoting bacteria (PGPR) improve growth under stress. This study aimed to isolate characterize rhizospheric endophytic from the rhizosphere roots a cucumber irrigated municipal wastewater. A total 121 morphologically distinct bacterial isolates 90 region were isolated tested for resistance vitro characteristics, indole-3-acetic acid (IAA) production, phosphate solubilization, Hydrogen Cyanide (HCN) siderophore production. Most analyzed regions showed characteristics tolerant different metals at concentrations. Bacterial strains R1 (Proteus sp.) E2 (Bacillus antagonistic Fusarium oxysporum f. sp.
