Plant growth promoting substances are widely used in modern agriculture. Several products in the market are humic substances isolated from different sources. The filter cake, a residue of sugar production, is a rich and renewable source of organic matter and these characteristics place the filter cake as a possible source of plant growth promoting substances. Humic acids (HA) from filter cake w...

Gene promoters perceive numerous signals and integrate this information into a single response, the transcriptional activity of a gene. It was speculated that covalent modification of histones on the promoters might have an important function in storage and integration of signals. Using the genes for the core proteins of C4 metabolism in maize as a model, we associated the perception of specifi...

The strongest signal of plant promoter is searched with the model of single motif with two types. It turns out that the dominant type is the TATA-box. The other type may be called TATA-less signal, and may be used in gene finders for promoter recognition. While the TATA signals are very close for the monocot and the dicot, their TATA-less signals are significantly different. A general and flexi...

Plants incessantly encounter abiotic and biotic stresses that limit their growth and productivity. However, conversely, plant growth can also be induced by treatments with various abiotic and biotic elicitors. Carrageenans are sulfated linear polysaccharides that represent major cellular constituents of seaweeds belonging to red algae (Rhodophyta). Recent research has unraveled the biological a...

The compatibility of strains is crucial for formulating bioinoculants that promote plant growth. We herein assessed the compatibility of four potential bioinoculants isolated from potato roots and tubers (Sphingomonas sp. T168, Streptomyces sp. R170, Streptomyces sp. R181, and Methylibium sp. R182) that were co-inoculated in order to improve plant growth. We screened these strains using biochem...

Abstract Microbial plant growth promoters (MPGP) are known to improve crop nutrition and root health. Here we examined the effects of individual combined inoculation chili pepper (variety Camino Real) with Rhizophagus irregularis (isolate BEG87) a commercial product Azospirillum brasilense on biocontrol against oomycete pathogen Phytophthora capsici CH11). In greenhouse pot experiment, unfertil...

We report here the draft genome sequences of two Arthrobacter strains isolated from a holm oak forest affected by wildfire. Both strains were shown to act as plant growth promoters, with AFG20 being a member of the most abundant group found in this soil and AFG7.2 being the strain with the highest indole-3-acetic acid production level.
