Summary: Auxins are a class of plant hormones that play roles in the establishment and maintenance of arbuscular mycorrhizal symbiosis (AMS). In this study, it was found that the transcription factors ARFs and AUX/IAAs in the auxin signaling pathway co-regulate the transcription of auxin response genes, highlighting their importance in the early stage of AMS. Additionally, SlARF6 was found to negatively regulate AMF colonization, while SlIAA23 promoted AMS and phosphorus uptake by interacting with SlARF6. Furthermore, SlARF6 and SlIAA23 played opposing roles in strigolactone synthesis and accumulation in AMF-colonized tomato roots.

Summary: The SPX-PHR regulatory circuit not only controls the balance of inorganic phosphate, but also regulates the transcription of PSI genes by blocking PHR1 activity. A study on tomato identified 17 members containing the SPX domain, and found that SlSPX1 and SlSPX2 were induced during phosphate starvation and AM fungi colonization. Silencing of SlSPX1 and SlSPX2 enhanced phosphate accumulation and growth in tomato seedlings, and promoted AM fungi colonization in roots. This study suggests that SlSPX members may be promising candidates for improving AM fungi colonization potential in tomato.

Summary: The Heirloom Golden tangerine tomato variety, rich in tetra-cis-lycopene, has high nutritional value and anti-inflammatory effects. The photoisomerization of tetra-cis-lycopene in the roots of the tomato plant affects root to shoot biomass, mycorrhizal colonization, abscisic acid accumulation, and responses to drought.

Summary: The study found that arbuscular mycorrhizae could enhance the dissolution of struvite, increase plant phosphorus uptake, and enhance biomass. Compared to monoammonium phosphate, struvite had a slower dissolution rate, but when treated with arbuscular mycorrhizae, the efficiency of plant utilization of struvite was improved.

Summary: Different fertilisation treatments positively affected tomato yield, phosphorus concentration, total nitrogen, manganese, and hydrophilic phenol contents in fruits, while volatile compounds were affected by the interactive effects of fertilisation and AMF application. The sensory quality indicators of tomato fruits were relatively modestly affected, with only a few sensory characteristics showing a lesser extent of change. Specific combinations of fertilisation and AMF inoculation were more effective at improving the quality parameters of tomatoes under field conditions in the study.

Summary: Drought stress is a major factor affecting agricultural production by negatively impacting plant growth and metabolism. Previous research has shown that viruses, such as the tomato yellow leaf curl virus, can enhance a plant's ability to tolerate both drought and heat stress. However, the underlying mechanisms for this induced drought tolerance need further investigation.

Summary: The study demonstrated that AMF can promote the absorption of silicon in tomato plants, with differing effects depending on the strain of AMF. The concentration of different forms of silicon in tomato rhizosphere soil was found to be in the order of citric acid-Si > NaOAc-HAc-Si > Oxalic acid-ammonium oxalate-Si > Na2CO3-Si > Na2HCO3-Si. AMF inoculation was shown to regulate the conversion of different silicon fractions in the rhizosphere soil.

Summary: Tomatoes are highly demanded in almost every country due to their gastronomic versatility and nutritional value. Factors such as drought, salinity, and inadequate temperature can decrease tomato yield and affect various metabolic pathways. Biotechnological tools can be used to alter tomato genes and improve its adaptability to abiotic stress. Biomimetic biotechnological approaches (BBA), which imitate nature's solutions, have gained attention for developing sustainable strategies to enhance tolerance in plants. In this review, genetic sequences and molecules that were targets of biotechnological intervention in tomatoes are discussed, along with the implications and perspectives within the GMO debate.

Summary: This study investigated the effect of arbuscular mycorrhizal fungi (AMF) on magnesium (Mg) nutrition in tomato plants. Results showed that Mg application promoted plant growth and mycorrhizal colonization. AMF inoculation had a positive impact on Mg acquisition in tomato plants under medium-Mg and high-Mg conditions. Additionally, the expression analysis of seven putative magnesium transporter (MGT) genes revealed significant alterations in response to the arbuscular mycorrhizal symbiosis (AMS).

Summary: Healthy soils play a crucial role in planetary survivability, providing not only calories but also other essential functions. However, intensive agriculture is rapidly degrading soils and diminishing their capacity to deliver vital functions, highlighting the need to focus on the multiple functions of soils for long-term human welfare and the survivability of the planet.

Summary: The aboveground ecological impacts of agricultural land use change are well studied, but the belowground impacts remain poorly understood. This study used soil physicochemical assessment and 16S rRNA gene sequencing to investigate the changes in soil physical properties and bacterial assemblages across an agricultural landscape. The results highlight the impact of agricultural inputs on soil nutrition and suggest that actions taken to restore native plant communities may also recover natural microbial communities, with implications for soil and plant health.

Summary: The study found that non-mycorrhizal plants were as successful as mycorrhizal plants in terms of N and water uptake under reduced and variable water availability. However, mycorrhizal plants showed lower water use efficiency and shoot N recovery, potentially due to their higher requirements for water and N. Non-mycorrhizal plants had greater specific root exudation, resulting in relatively greater uptake of N than P across all watering conditions.

Summary: High-throughput phenotyping was used to evaluate growth responses of tomato plants with different rates of nitrogen and phosphorus application. The results showed that readily available soil phosphorus was important for early growth, while available nitrogen was more important in later stages. A fertilizer formulation combining inorganic and organic phosphorus sources could sustain rapid shoot growth and reduce the need for additional nitrogen input.

Summary: Major shifts in vineyard floor management have occurred in the past thirty years. Initially, intensive tillage led to soil erosion, soil structure degeneration, and increased use of herbicides. However, concerns over herbicide toxicity and resistance have resulted in a shift towards reduced herbicide usage and increased tillage. The study found that low-intensity management strategies can lead to higher plant diversity, improved soil water infiltration, and higher levels of soil nutrients.

Summary: Inoculation of soil with living microbes or propagules has gained attention and application for modifying/degrading soil systems and maintaining agricultural yields. However, the utilization of beneficial microorganisms as an agronomic tool for large-scale agriculture remains relatively insignificant. This review emphasizes the need to understand the role of soil microbes in soil carbon cycling, in order to develop products capable of supporting soil carbon sequestration and retention.

Summary: Sorghum, an important cereal crop, can benefit from symbiosis with arbuscular mycorrhizal (AM) fungi to enhance yield, nutrient uptake, and grain quality. Research shows that sorghum genotypes exhibit high responsiveness to AM colonization, leading to increased grain production and nutritive value. By effectively managing the symbiotic relationship with AM fungi, it is possible to improve the overall outcomes of sorghum cultivation.
