Summary: Prince Rupprecht's larch, a native conifer in North China, has great economic and ecological values. Somatic embryogenesis (SE) was established as a high-efficiency system for mass clonal propagation in plants, with factors such as genotype, culture conditions, and phytohormones influencing the process. By optimizing culture conditions and hormone levels, successful proliferation and maturation of somatic embryos were achieved in this study.

Summary: A methodology to expand eddy tracking capacity is proposed by utilizing altimetrically calibrated Argo measurements, aiming to tackle the issue of missed oceanic eddies due to inadequate spatiotemporal sampling by available altimeters. The independent identification scheme relates the surface signature of eddies to their interior property, effectively identifying additional eddies overlooked by altimeters and rectifying their ineffectiveness in certain regions. The approach demonstrates a highly complementary nature of combining altimetry and Argo profiling arrays for eddy identification.

Summary: The cryopreservation of olive somatic embryos using droplet-vitrification method affected the somatic embryogenesis process and its outcomes varied depending on the genotype. Specifically, the Line T1 showed higher fresh weight increases and the Line P5 exhibited improved maturation pattern and germination results after cryopreservation. Genotype plays a key role in determining the impact of cryopreservation on olive somatic embryogenesis.

Summary: Studies have shown the importance of positive interactions between genotypes in wild plant species, influenced by kin selection theory and the elbow-room hypothesis. However, there are shortcomings in existing research, such as a lack of reliable estimates of genetic relatedness among genotypes and ecological characterization of natural habitats. A combination of evolutionary ecology and genomics is proposed to establish the eco-genomic landscape of positive genotype-by-genotype interactions in wild plant species.

Summary: Conventional plant regeneration methods are tedious and time-consuming. Recent studies have identified key growth and developmental regulatory genes that can greatly improve regeneration efficiency and make transformation of difficult genotypes possible. Utilizing these regulatory genes offers the potential to develop innovative genotype-independent genetic transformation methods for plants.

Summary: We conducted a high throughput metabolomic screening using UHPLC-TWINS-QTOF on different parts of R. usambarensis. Through the use of high-resolution mass spectrometry-based metabolomics and chemometric analysis, we were able to distinguish between different aerial parts and identify 153 significant metabolites in leaves, stems, and flowers. The results suggest that flavonoids, benzopyranes, chromones, and xanthones derivatives, along with a richer phytocomplex, may be responsible for the stronger bioactivities obtained from flowers.

Summary: Plant cell cultures of various yew species have the ability to synthesize taxoids, predominantly of the 14-OH taxoid group. In this study, 14-hydroxylated taxoids were identified and isolated from suspension cultures of Taxus baccata cells. Regardless of the species and culture conditions, most cell lines retained the ability to form taxane diterpenoids, with nonpolar 14-hydroxylated taxoids being the predominant form.

Summary: In 2015, a collapse of a mine dam in the Southwest of Brazil resulted in the release of millions of tons of sediments into an estuary. The contaminated soil is still highly polluted with metals, possibly leading to the selection of microorganisms capable of surviving in such harsh conditions. In this study, we isolated metal(loid) and antibiotic resistance bacteria from the polluted estuarine soil. After identifying the strains through 16S rDNA sequencing, we focused on the Mucilaginibacter sp. strain due to its potential as a bioprospector and its high resistance profile. We successfully obtained the complete genome of this strain and conducted a genome-guided characterization. Our findings suggest that the strain 21p may be a new species of the genus, exhibiting resistance genes for metals and cross-resistance for antibiotics. Further exploration of the Mucilaginibacter sp. 21p as a new species is warranted, considering its extracellular polymeric substances and its potential for bioremediation and growth promotion in highly metal(loid)-contaminated soil.

Summary: This study found that microbial diversity in cultivated soils plays a significant role in the dissipation of ATZ, with the higher diversity attributed to adaptation of microbial groups to previous exposure to ATZ. In cases with higher diversity, ATZ dissipation was mainly attributed to mineralization.

Summary: Root-knot and root-lesion nematodes cause significant economic losses to agriculture worldwide. Chemical nematicides have been traditionally used for their control, but they have negative effects on the environment and human health. The soil microbial community may serve as an environmentally friendly alternative to control these pests. However, the effects of soil microbial diversity on plant-parasitic nematodes are still poorly understood. This study provides fundamental insight into the interactions between soil bacterial diversity and plant-parasitic nematodes in soybean plants, which can potentially aid in the development of new strategies for nematode control.

Summary: Cattle ranching in the Brazilian Amazon is the main cause of deforestation. The conversion of rainforests to pasture affects the methane cycle in soil, changing it from absorbing to emitting methane. This study found that maintaining grass coverage on pasture soils can reduce methane emissions, while liming the soil can increase methane emissions and reduce the population of methane-metabolizing bacteria in forest soils.

Summary: We hypothesized a positive correlation between soil bacterial diversity and phosphorus availability from soluble or less soluble sources under maize cultivation. This hypothesis was evaluated using a mesocosm experiment and the dilution-to-extinction methodology to generate a gradient of soil bacterial diversity. The results showed a negative correlation between bacterial diversity index and labile P fraction in soil, as well as P content in maize. Enrichment of P-mineralizing microorganisms was observed at higher microbial dilutions, potentially affecting plant development.

Summary: Land-use change has negative impacts on the biodiversity of plants and animals, but studies on the impacts of land-use change on soil microorganisms, particularly those involved in the phosphorus transformation processes, are lacking. This study used DNA-metagenomic sequencing and P fractionation analysis to assess the effects of forest-to-pasture conversion on soil bacterial groups involved in P transformation processes. The results showed that land-use change altered soil P dynamics and bacterial community structure.

Summary: Biological nitrogen fixation is essential for the development of soybean plants, but management decisions such as pesticide use and timing of Bradyrhizobium sp. inoculation can negatively impact soybean growth and yield. This study evaluates the effects of pre-inoculating soybean seeds with Bradyrhizobium sp. and pesticides seed treatment on biological nitrogen fixation under laboratory, greenhouse, and field conditions. The results show that both pre-inoculation and pesticide seed treatment can reduce the recovery of Bradyrhizobium colonies, ureides concentration, biological nitrogen fixation efficiency, and plant growth. Field experiments also demonstrate that specific pesticides can cause significant yield loss and that inoculation closer to sowing can lead to higher grain weight.

Summary: This study investigated the composition and structure of bacterial and archaeal communities in tropical soils under different land-use changes, with a focus on the methanogenic communities. It was found that pastures harbor a richer and more responsive methanogenic community, suggesting that converting forest areas to pasture may increase methane emissions.

Summary: Common fertilizers have low use efficiency due to nutrient losses, limiting crop production. Inoculation with Plant Growth-Promoting Bacteria (PGPB) is proposed as an alternative to increase fertilizer efficiency. This study aimed to test the hypothesis that PGPB can increase the efficiency of monoammonium phosphate (MAP), root growth, and nutrient assimilation of soybean and corn. Results showed that PGPB + MAP increased soil biological activity and crop root growth. Plant dry matter was positively correlated with soil phosphorous content, indicating increased phosphorous assimilation. In conclusion, PGPB + MAP enhances the growth and phosphorous accumulation of soybean and corn, with a direct effect on crop rooting.
