Aim: To understand how beneficial bacteria assist chilli plants (Capsicum annuum) in defence against biotrophic or hemibiotrophic pathogens.
Method And Results: We quantified marker genes of plant defence pathways in Phytophthora capsici-infected chilli pepper treated with anti-oomycete plant growth-promoting rhizobacteria, Bacillus amyloliquefaciens, Bacillus velezensis and Acinetobacter sp. Plants displayed strong resistance, and the pathogen load in the roots was significantly lower in infected plants treated with bacterial biocontrol agents at all time points tested (1, 2 and 7 days after pathogen inoculation, p < 0.
Article Synopsis
- High-yielding microalgae like Nannochloropsis oceanica are crucial for meeting the increasing demands for food, feed, and biofuels, and their productivity can be influenced by associated bacteria.* -
- Researchers identified and selected effective "probiotic" bacterial strains that, when co-cultivated with N. oceanica, increased culture density and biomass significantly, along with boosting eicosapentaenoic acid (EPA) content.* -
- The probiotic bacteria showed growth-promoting traits such as nitrogen fixation and hormone production, and the main bacterial communities associated with N. oceanica included various types of bacteria, suggesting that adding these probiotics can greatly enhance both biomass and EPA yield.*
strains BR2 and KB1 are microalgal isolates from brackish water in the Brisbane River and a coastal rock pool at the Sunshine Coast in Australia which display superior productivity at high temperatures. We used long-read sequencing to sequence their genomes and to facilitate elucidation of loci associated with these traits.

Accordingly, we used long-read sequencing to determine its complete genome sequence. The assembled genome will aid in understanding the multifaceted interactions between plant growth-promoting rhizobacteria, pathogens, and plants.

Three out of 48 isolates exhibited more than 65% inhibition against all tested species and were selected for further studies. These strains, named UQ154, UQ156, and UQ202, are closely related to , , and sp.

- Researchers studied Tetraselmis sp. M8 to understand how lipid pathways contribute to rapid triacylglyceride buildup after nitrogen exhaustion.
- RNA-Seq and real-time PCR showed a significant change in gene expression related to fatty acid/triacylglyceride production and breakdown during different growth phases.
- The findings suggest that increased lipid accumulation occurs due to reduced breakdown of lipids and enhanced production during the stationary phase, independent of the DGAT gene, which is typically important for lipid storage.
