Summary: In the field of plant disease control, the identification of bacterial strains as Pseudomonas marginalis was based on characteristics such as fluorescence, oxidase negativity, potato soft rot, and positive arginine dihydrolase. However, with the introduction of phylogenetic and genomic analyses, it was discovered that Pseudomonas marginalis is heterogeneous and may contain many cryptic species. A survey was conducted to sort the strains preserved in the NARO Genebank into Pseudomonas marginalis sensu stricto and other strains. Some of these strains were found to be novel species, including Pseudomonas kitaguniensis, Pseudomonas allii, Pseudomonas cyclaminis, Pseudomonas petroselini, Pseudomonas brassicae, Pseudomonas lactucae, Pseudomonas aegrilactucae, and Pseudomonas morbosilactucae. This article briefly introduces the profiles of these novel species and discusses the challenges in reorganizing Pseudomonas marginalis sensu lato.

Summary: This study investigated the chromosome evolution of Crepis plants by analyzing the chromosome base number and organization of rDNA loci in 39 species. The results showed that despite variations in rDNA loci organization, most species had rDNA loci on the same chromosome arm. Comparative analysis revealed multiple independent gains of rDNA loci and repositioning during diversification and speciation. These findings provide important insights into the evolutionary mechanisms and speciation of Crepis plants.

Summary: The study found that the presence of human pathogenic Bb affected the composition of tick microbiome, shifting the abundances of various microorganisms. Furthermore, the location had less impact on tick microbiome composition, but significantly altered the abundance of specific bacterial species and their topological roles. The regional variation in presence of Bb and other tick-associated pathogens suggests the importance of implementing a bacterial 16S rRNA gene-based microbiome survey for optimizing therapeutic approaches against Bb infection and co-occurring pathogens.

Summary: The extraction and commercialization of palm hearts is highly profitable, but the consumption of peach palm fruits is limited to Amazonian communities. The focus on germplasm banks has hindered the development of high-performance varieties, resulting in limited production and consumption. With the fragmentation of the Amazonian rainforest, wild populations of peach palm are at risk of extinction. Further research is needed to understand the impact of climate change on plant performance. Exploiting the full potential of peach palm is crucial for expanding plantations and promoting its market expansion as a fruit crop.

Summary: Animals use different strategies to balance the efforts and energy they expend for obtaining food resources and the nutritional returns. This study found that the termite Constrictotermes cyphergaster reacts differently to food resources at different heights, spending less time and traveling shorter distances for resources on the ground compared to those on live trees. The result suggests that the termites consume the bark and twigs of live trees for their potassium contents rather than to fulfill energetic demands.

Summary: Among the adenylate carriers in Arabidopsis thaliana, increased expression of the AMP/ATP transporter ADNT1 is observed in roots under waterlogging stress conditions. The reduced expression of ADNT1 leads to decreased maximum quantum yield of PSII electron transport and higher levels of AMP in roots under nonstress condition. ADNT1-deficient plants exhibit differential expression of hypoxia-related genes and metabolic reprogramming associated with early induction of the fermentative pathway.

Summary: Competition with weeds limits forest species development. Some herbicides have residual effects on the soil. This study evaluated the tolerance and degrading potential of fungi (Aspergillus niger, Penicillium pinophilum, and Trichoderma sp.) and bacteria (Bacillus subtilis, Pseudomonas sp., and Azospirillum brasilense) to herbicides. The tested herbicides had no significant effect on bacterial growth, and all fungi were tolerant to the herbicides. Trichoderma sp. showed increased growth in the presence of certain herbicides. The tested residual herbicides did not interfere with the growth of evaluated microorganisms.

Summary: Studies on gully processes in the Brazilian semiarid region are rare, and the existing ones mainly focus on morphology. Unlike humid regions, gully processes in this area are affected by limited groundwater infiltration due to low-permeability layers near the surface. This study aims to investigate the principles behind the genesis and evolution of gullies in the semiarid portion of the Borborema Plateau. Aerial photogrammetric surveys using a drone were conducted, and soil profiles were analyzed to understand the physical and chemical properties. The results indicate active gully processes and the influence of local hydrogeomorphological factors and soil characteristics.

Summary: The development of fleshy fruits involves changes in size, mass, cell differentiation, anatomical and histological changes, and metabolic alterations. The regulation of metabolism and its association with anatomical changes in non-climacteric fruit development are poorly understood. In this study, three developmental phases of chili pepper were defined, each marked by distinct metabolic profiles. Mitochondrial activity was high in the early stages of development and declined over time, with a respiratory-like burst at the beginning of the ripening stage.

Summary: The rupture of the Funda similar to o dam in Mariana-MG, Brazil resulted in iron ore tailings that impacted the Doce River basin, affecting the flora and fauna in the region. Plants in contaminated soil showed changes in metabolism, reduced growth and biomass, and phytotoxicity symptoms. However, some species were able to exclude or accumulate metals through adaptive strategies. In this study, we investigated the physiological and metabolic responses in Restinga shrub species affected by the mining plume from the contaminated sea. We found that the rainy season led to the accumulation of metals and higher levels of these metals at the sampling stations. Increased stomatal conductance and intercellular CO2 concentration were observed during the rainy season, which was characterized by high temperatures. The results showed correlations between metals and metabolic responses, indicating acclimation responses such as maintenance of photosynthesis, and accumulation of free amino acids, carbohydrates, and antioxidants. The differential physiological responses between the two species analyzed suggest a genetic load capable of partially responding to stressful conditions associated with the iron ore tailing plume.
