Summary: This study successfully isolated two beneficial Trichoderma strains from wheat in Lebanon, which were found to promote root growth, produce plant growth hormones, and inhibit the growth of pathogenic fungi in vitro. These Trichoderma strains have the potential to be used as organic fertilizers for wheat.

Summary: The biosynthesis of auxin by microorganisms, such as Penicillium citrinum isolate B9, has a major impact on plant growth and development. Fungal auxin secretion enhances root and shoot development, as well as overall plant growth in Arabidopsis thaliana. The production of auxin by P. citrinum likely involves multiple tryptophan-dependent pathways, and it exerts its effects by enhancing auxin signaling in roots.

Summary: This study identified miRNAs associated with lateral root development in sandalwood through sRNA high-throughput sequencing of root tissues. A model of miRNA-regulated lateral root development was proposed for this hemiparasitic species. These novel genetic information has important implications for improving sandalwood root growth and development.

Summary: The transcription factor HB24 in the zinc finger-homeodomain family was found to regulate root hair elongation by upregulating the expression of IBR1, which is involved in the conversion of IBA to IAA. This study demonstrates a feedback loop involving HB24 and IAA in the mediation of root hair elongation.

Summary: Inoculating barley and chickpea with Klebsiella strains capable of producing auxin significantly increased nitrogen use efficiency and nitrogen uptake efficiency, leading to reduced nitrogen fertilizer application. The study showed that the enhanced root surface area contributed to the improved nitrogen acquisition in the plants, with the auxin producers outperforming the non-auxin producer in terms of NUE and NUpE.

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 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: Indole-3-acetic acid (IAA) is an important plant hormone that regulates plant growth and development. It also plays a significant role in microorganisms, affecting their growth, development, and interaction with plants. Understanding the biosynthesis and functions of IAA in microorganisms can help improve its production and utilization in agriculture.

Summary: This study found that plant inclination increases with decreasing row spacing in the maize-soybean intercropping system, while brace unilateral root growth ratio tends to increase with plant inclination. Plant inclination can affect brace unilateral root growth by regulating IAA levels.

Summary: This paper investigates the changes in the anatomy and cell wall architecture of maize roots in the presence of auxin indole-3-butyric acid (IBA) and Cd. The application of IBA delayed the development of apoplastic barriers, decreased lignin content in the cell wall, increased the content of Ca2+ and phenols, and influenced the composition of monosaccharides in polysaccharide fractions. IBA improved the Cd2+ fixation to the cell wall and increased the endogenous concentration of auxin depleted by Cd treatment.

Summary: Recent research has found that polystyrene nanoplastics (PS-NPs) can hinder the growth of plants and crops, including rice. This study aimed to examine the impact of PS-NPs of different sizes and charges on rice growth, as well as investigate the underlying mechanisms and potential strategies to mitigate their effects. The results showed that positively charged PS-NPs (80 nm PS-NH2) had the most significant negative impact on rice growth, reducing dry biomass, root length, and plant height.

Summary: The study aims to mitigate the adverse effects of water stress on pigeon pea plants by using rhizospheric bacteria and the exogenous application of indole acetic acid and gibberellic acid. The results showed that treating bacterial isolates and exogenous hormones positively affected morphological and physiological characters, leading to increased osmolytes production, enhanced photosynthetic activity, and improved mineral uptake. This resulted in increased plant growth and improved sustainable agriculture.

Summary: The pseudometallophyte Rumex acetosella L. inhabits regions with high soil concentrations of zinc, lead, and copper. Comparisons between populations from contaminated and non-contaminated soils in Slovakia showed that metallicolous populations have higher metal contents, stomata and trichome density, as well as complex labyrinth structures within the cell wall. These findings suggest plant adaptations to metal stress for survival in contaminated environments.

Summary: Short-term Cd treatment induces changes in gene expression in barley root tips via IAA and ROS signaling during mild and severe Cd stress. The early activation of MYB1 transcription factor expression is partially regulated by auxin signaling in mildly stressed seedlings. Alterations in gene expression in response to Cd stress are related to IAA and ROS levels in the cells.

Summary: The use of NBT and HE is efficient for detecting superoxide in intact barley root tips, while DCDHF-DA and DHR123 are suitable for the detection of peroxynitrite, but only if PRXs and oxidoreductases are inhibited to prevent false-positive reactions.
