Summary: In this study, the bacteria and fungi in the rhizocompartments of dominant plants in the littoral zones of Sunit Al-kali Lake were analyzed using high-throughput sequencing technology and molecular ecological networks. The study found that fungal communities were more tolerant of environmental stress, and salinity was not the main factor affecting microbial composition. Soil organic carbon was identified as the primary environmental factor affecting the rhizosphere bacteria and fungi, while carbonate ions had a greater impact on the rhizosphere fungal communities. The study is significant for understanding salt environments and exploring potential microbial resources.

Summary: One of the main constraints on agricultural productivity is the low availability of iron in the soil, which affects plant development and physiology. The concentration of iron accessible to plants and microbes in cultivated soil is limited, mainly due to the properties of the soil and the solubility of iron. Plants and soil microorganisms employ active strategies to enhance soil iron availability, such as acidification, chelation, and reduction. Understanding the dynamics of iron in the rhizosphere is crucial for improving plant growth and health.

Summary: Land reclamation significantly affects phosphorus (P) transformation and availability in soils. P-solubilizing microorganisms (PSMs) play crucial roles in activating soil P. However, the responses of PSMs to P buildup during land reclamation and the relationship between different P fractions and PSMs remain unclear. This study investigated three treatments (vegetable field, cropland, and uncultivated land), measured different P fractions, determined the stable oxygen isotope abundance in phosphate, and analyzed the diversity, composition, and co-occurrence network of P-solubilizing glucose dehydrogenase community (gcd).The results showed that soil total P increased significantly in the vegetable field and cropland treatments compared to the uncultivated land. Labile and moderately labile P proportions were higher in the vegetable field and cropland treatments. The α-diversity of gcd community was greater in the vegetable field and cropland treatments. Changes in gcd community structure were associated with different P fractions. The co-occurrence networks in the vegetable field and cropland treatments were more complex than in the uncultivated land. In conclusion, land reclamation led to P accumulation, particularly in labile and moderately labile P fractions, and enhanced the complexity and robustness of the gcd community's co-occurrence network.

Summary: By conducting a pot experiment, the potential of Eruca sativa (rocket) as a selenium (Se) enriched plant was investigated. The experiment showed that rocket has the ability to accumulate high concentrations of Se and has the potential to promote human health. The addition of different rates of selenite or selenate to the soil influenced the uptake of Se by the plants, and there was a possible interaction between Se, sulfur (S), and phosphorus (P). The results also indicated that rocket could effectively accumulate and store Se under certain conditions.

Summary: A study was conducted in greenhouse vegetable production areas in China to assess the degree of magnesium (Mg) deficiency in tomato plants. The tomatoes showed Mg deficiency, with no farms supplementing this element. Ward's hierarchical cluster analysis identified three clusters of Mg leaf content, with different levels of deficiency and corresponding differences in tomato yields and soil nutrient content. The study suggests that foliar Mg spraying can mitigate Mg deficiency in calcareous greenhouse tomato soil.

Summary: Hybridization and polyploidy are important forces in plant adaptation and speciation. Interspecific gene flow generates adaptive genetic variants and increases yield in crops. The frequency of interspecific hybridization varies among taxa, with an estimated 9% occurrence. Allopolyploidy is more common than homoploid hybrid speciation. Chromosome doubling after hybridization is caused by cellular defects during meiosis. Unreduced gametes, formed at a frequency of 2.52% on average, result from altered spindle organization, disrupted kinetochore functioning, abnormal cytokinesis, or loss of meiotic division. Meiotic changes leading to cytological diploidization in allopolyploids are being understood, particularly in wheat. However, the understanding of homoeologous recombination suppressor genes in other allopolyploids is limited. The merger of two genomes leads to architectural, gene expression, and molecular interaction changes, resulting in phenotypic differences. This article provides an overview of genomic and transcriptomic changes during the early stages of allopolyploid formation.

Summary: To cope with nutrient scarcity, plants employ two main strategies - stopping growing to reduce nutrient demand, and searching for nutrients through physiological and morphological responses in roots. The interconnection between these strategies is not well understood, but recent research suggests that the plant hormone ethylene may play a crucial role in connecting them. The TOR system is known to be a central regulator of growth in response to nutrients, and ethylene activation is involved in many nutrient deficiency responses.
