Summary: The Ve-resistance locus in tomato acts as a resilience gene by affecting both the stress/defense cascade and growth, constituting a signaling intercept with a competitive regulatory mechanism. Recent molecular studies suggest that the Ve-locus and the two proteins that it encodes have more complex functions and roles than previously understood.

Summary: Oxidative stress and infection are major factors delaying wound healing, with potential to cause inflammation and prolonged recovery. This study introduces a novel tissue engineering scaffold called SL/GelMA, developed using tomatoes and gelatin methacryloyl. By utilizing the natural antioxidative components found in tomatoes, such as carotenoids, flavonoids, phenolic acids, vitamin E, and vitamin C, SL/GelMA effectively regulates ROS levels, reduces oxidative stress, promotes cell migration and angiogenesis, and accelerates wound enclosure rate.

Summary: Reduced growth habit in ornamental potted plants can be achieved through Rhizobium rhizogenes transformation or Agrobacterium tumefaciens transformation with specific genes. Different rol genes and ORFs play a role in compact phenotype, with rolB2 and ORF14-2 showing reduced growth traits and ethylene tolerance in a study on Kalanchoe blossfeldiana 'Molly'. Single or low gene copy insertion correlates with higher gene expression in rolB and Delta ORF13a lines, while increased gene expression in rolB2 and Delta ORF13a-2 led to more compact plant growth.

Summary: The study investigated the effects of copper, silver, and zinc oxide nanoparticles on tomato plants and their symbiotic relationship with an endophytic fungus. Results showed that nanoparticles had toxic effects on the fungus, leading to inhibition of growth and spore germination, as well as impacting plant root length and dry weight. Additionally, a oxidative stress response was observed in treated plants, with reduced chlorophyll levels. The presence of the endophyte in roots seemed to alleviate the toxicity of certain nanoparticles, suggesting a potential reciprocal benefit between the fungus and the plant.

Summary: Casuarina equisetifolia is widely used for agroforestry plantations for various purposes. This study established an efficient regeneration system using stem segment explants, optimizing callus induction and regeneration processes. Genetic transformation protocol using Agrobacterium tumefaciens was also optimized, leading to improved transformation efficiency to obtain transgenic plants in about 4 months. The findings will pave the way for further genetic manipulation and functional genomics of C. equisetifolia.

Summary: This study identified fitness genes of Agrobacterium tumefaciens involved in reproductive success on plant tumors and roots, with some genes affecting bacterial virulence. Chemical and biocontrol treatments targeting these pathways were found to reduce tumorigenesis and establishment of A.tumefaciens on plant roots, providing insights for plant protection approaches against this pathogen.

Summary: Rhizogenic Agrobacterium strains are biotrophic pathogens that infect hydroponically grown Solanaceae and Cucurbitaceae crops, causing hairy root disease (HRD). They are also widely used for hairy root cultures to produce specialized plant metabolites. The development of hairy roots is regulated by genes encoded on the T-DNA of the root-inducing (Ri) plasmid, including the important rolB gene. In this study, through proximity labeling in tomato hairy roots, the repressor proteins TOPLESS (TPL) and Novel Interactor of JAZ (NINJA) were identified as direct interactors of RolB. The interactions between RolB, TPL, and NINJA were found to play a role in the transcriptional regulation and reprogramming of phytohormone signaling, immunity, growth, and developmental processes in the host plants.

Summary: Fruit formation is dependent on successful fertilization and is susceptible to weather fluctuations affecting pollination. The auxin hormone plays a role in fruit initiation and growth after fertilization. This study examines the regulation of fruit set and growth by the ARF family in tomato and Arabidopsis, and demonstrates that reducing the activity of SlARF8 genes can improve yield stability in fluctuating temperatures.

Summary: Curdlan, a water-insoluble exopolysaccharide produced by Agrobacterium species under nitrogen starvation, was significantly impaired in AmdeA, AmetA, AmetH, and AmetZ mutants. The impaired curdlan production was associated with down-regulation of genes involved in the electron transfer chain (ETC) and accumulation of ADP and FAD in the AmetH and AmetZ mutants. Addition of dibasic sodium succinate and methionine restored curdlan production in the mutants, indicating the importance of the methionine biosynthesis pathway in energy ATP supply during curdlan biosynthesis.

Summary: The study found that increasing salinity stress led to a decrease in various growth parameters of tomato seedlings and an increase in Na content. Salt-tolerant cultivar 'PS-10' showed better osmotic adjustment and higher antioxidant enzyme activity under salinity stress compared to other cultivars. The use of iron and zinc oxide nanoparticles improved callus induction and plant regeneration under salinity stress in different tomato cultivars, highlighting their potential for future breeding programs.

Summary: Acid soil syndrome is a global phenomenon characterized by low pH, nutrient scarcity, and mineral toxicity. The detrimental effects of low pH on crop development, particularly root growth, are still poorly understood and underrated. Future studies combining genetic tools are needed to uncover the signaling processes triggered by low pH and find new ways to enhance the tolerance of domesticated plants to acidic stress.

Summary: Research shows that endogenous nitric oxide (NO) plays a regulatory role in tomato shoot architecture, fruit set, and growth. Inhibiting S-nitrosoglutathione reductase (GSNOR) in tomato promotes shoot side branching and reduces fruit size, negatively impacting fruit yield. It was also found that GSNOR inhibition results in increased protein tyrosine nitration and S-nitrosation, affecting auxin production and signaling in leaf primordia and developing ovaries of fruits.

Summary: The study identified a genetic locus on chromosome 7 in tomato that controls both vegetative and reproductive organ size, with alleles from wild species leading to lower cell number and reduced size of leaves, flowers, and fruits in introgression lines. The findings suggest that selection for large fruit during domestication also influences leaf size by altering cell division, potentially allowing for fine-tuning of parameters important for crop adaptation.

Summary: The interplay between miR156 and GAs in tomato controls flowering time and subsequent stages of reproductive development. High GA responses or overexpression of miR156 lead to enlarged floral meristems, indeterminate ovaries, and fruits with increased number of locules. Low GA responses reduce indeterminacy and locule number. The miR156/SlSBP/GA regulatory module is deployed differently depending on the developmental stage, and this study provides new opportunities for fine-tuning aspects of fruit development in tomato domestication.

Summary: This study investigated the response of cyanobacteria Raphidiopsis raciborskii to nitrogen limitation and its genetic background, shedding new light on heterocyte production and phylogeography. The findings suggest that heterocyte development in R. raciborskii is not regulated by nitrogen availability. Genetic analysis revealed differences between strains. The study also confirmed Raphidiopsis and Cylindrospermopsis as the same genus and proposed new hypotheses on the biogeography of the species.
