Summary: In this study, the mechanisms of fluoranthene (Flu) uptake and accumulation in Arabidopsis thaliana were investigated using two IAA-sensitive genotypes. The results showed that Flu concentration in Axr5 leaves was higher than that in wildtype leaves. The Flu content in roots decreased significantly with increasing IAA treatment. Principal component analysis revealed that Flu accumulation in roots was associated with IAA concentrations, while Flu accumulation in leaves depended on the genotype. Furthermore, several genes and transcription factors were identified as important regulators of Flu accumulation.

Summary: In Tunisia's arid and semi-arid lands, drought stress is the most critical factor limiting agricultural production due to low and irregular precipitation. The scarcity of underground water for irrigation and climate change have further intensified and expanded the aridity. Exploring genotypic variability to identify tolerant genotypes and useful tolerance traits is an efficient and sustainable approach to mitigate drought stress.

Summary: Soil salinity negatively affects plant growth and production. A plant growth-promoting bacteria (PGPB), identified as the I4 strain of Bacillus mojavensis, was isolated from Tunisian soil and showed the ability to tolerate high NaCl concentrations. Inoculating wheat plants with the I4 strain improved their growth, preserved membrane integrity, and enhanced their stress adaptation. These findings suggest that the use of PGPB as biofertilizers can help enhance wheat growth in saline soil and contribute to food security in challenging global conditions.

Summary: The hydrolysis product of indole-3-methylglucosinolate, indole-3-carbinol (I3C), is toxic to herbivorous insects and pathogens, while extensively studied in mammals for its properties in cancer prevention and treatment. A novel Arabidopsis mutant, ICT1, has been identified to be tolerant to I3C, with the tolerance mechanism involving the S30 ribosomal protein. The tolerance is specific to I3C and maintained the antagonistic action of I3C on auxin signaling through an auxin-independent mechanism.

Summary: This study discovered the abundance of Pseudomonas genera as high phosphate accumulators in soil. The presence of functional genes (polyphosphate kinase [ppk] and exopolyphosphatase [ppx]) in all PAB indicates their importance in polyphosphate metabolism in bacteria. Genetic and functional diversity reveals conservation of the ppx gene at the species level. Furthermore, a positive correlation was found between PAB and plant growth promotary traits, stress tolerance, and salinity stress alleviation in A. thaliana.

Summary: The salinity of soil is an important environmental problem, especially in arid and semiarid areas, and is becoming more relevant due to climate change. This study used RNA-Seq analysis to identify key genes involved in the response to salt stress induced by Arbuscular Mycorrhizal Fungi (AMF) in durum wheat. The findings revealed the enhancement of genes related to plant stress responses and modulation of gene expression involved in various metabolic pathways. The study also found differential expression of transcription factors known to play a key role in plant abiotic stress response. These insights contribute to our understanding of AMF-induced gene expression modulation and the beneficial effects of plant-AMF interaction in wheat under salt stress.

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: This study investigated the effect of different concentrations of NaCl on the germination process of Triticum durum grains, and found that the optimal salinity level for maximizing the production of phytochemicals, particularly phenolic compounds, needs further investigation. The results showed that higher concentrations of NaCl significantly affected germination performance. Salinity induced the accumulation of phenolic compounds in both roots and shoots, with the highest accumulation observed at 200 mM NaCl.

Summary: In this study, it was found that the transcription factor VhMYB2 played an important role in the resistance of the 'Beta' rootstock to salinity and drought stress. VhMYB2 was predominantly expressed in the mature leaf and root of the grape, and overexpressing VhMYB2 increased the resistance and survival rates of Arabidopsis thaliana under salinity and drought stress. These findings suggest that VhMYB2 may be a key transcription factor regulating the resistance of 'Beta' to abiotic stress.

Summary: This study reveals that the ATS1 gene negatively regulates salt resistance in Arabidopsis. Overexpression of ATS1 leads to decreased salt tolerance in terms of seed germination, biomass, chlorophyll content, pod development, and increased root/shoot ratio and anthocyanidin content. Mutations in the ATS1 gene result in higher levels of unsaturated fatty acids, which stabilize the plasma membrane under salt stress. The ats1 mutants also regulate ion homeostasis by upregulating K+ uptake and downregulating Na+ uptake genes.

Summary: The study revealed that the conversion of PAOx to PAA does not require glucosinolates in Arabidopsis, and maize can produce PAA and IAA from PAOx and IAOx, respectively, indicating that aldoxime-derived auxin biosynthesis is widely present in different plants. The genome-wide transcriptomics study using PAOx-overproduction plants identified complex metabolic networks among IAA, PAA, phenylpropanoid and tryptophan metabolism, suggesting the potential of aldoxime-derived auxin biosynthesis to be more widespread than previously believed.

Summary: The Aneurinibacillus migulanus (A. migulanus) strains Nagano and NCTC 7096 have been proven to be powerful biocontrol agents against plant diseases. The cyclic peptide gramicidin S (GS) produced by both strains plays a major role in inhibiting bacteria and fungus-like organisms. A mutant of the Nagano strain impaired in GS biosynthesis showed a total loss of biocontrol ability, highlighting the importance of GS in the biocontrol potential of A. migulanus Nagano strain.

Summary: Abiotic stress, especially drought, severely inhibits plant growth and agricultural productivity on a global scale. Plants employ various morpho-anatomical, physiological, and biochemical strategies to cope with water stress, including changes in root and leaf structure, hormone balance, antioxidant systems, and osmolyte accumulation. However, the use of osmotolerant plant growth-promoting rhizobacteria (PGPR) as inoculants can enhance plant tolerance to drought by improving root morphology, hormonal production, and osmolyte accumulation, as well as regulating stress response genes. This review highlights the potential of PGPR in modulating the physiological response to water scarcity and enhancing the growth and resistance of agricultural crops.
