“…Based on phylogenetic analysis, S. habrochaites and S. peruvianum are classified into the Eriopersicon group, while S. pimpinellifolium and S. lycopersicum are sister species and grouped under the Lycopersicon group (Blanca et al, 2022; Ramírez‐Ojeda et al, 2021; Yu et al, 2022). These three wild species accessions have been used in breeding programmes for commercial tomato plants to develop resistance against pests and diseases (Baldin et al, 2005; Mansilla‐Córdova et al, 2018; Zeist et al, 2021).…”

The relationship between plants and pollinators is known to be influenced by ecological interactions with other community members. While most research has focused on aboveground communities affecting plant–pollinator interactions, it is increasingly recognized that soil‐dwelling organisms can directly or indirectly impact these interactions. Although studies have examined the effects of arbuscular mycorrhizal fungi on floral traits, there is a gap in research regarding similar effects associated with plant growth‐promoting rhizobacteria (PGPR), particularly concerning floral scent. Our study aimed to investigate the influence of the PGPR Bacillus amyloliquefaciens on the floral traits of wild (Solanum habrochaites, Solanum pimpinellifolium and Solanum peruvianum) and cultivated tomato (Solanum lycopersicum), as well as the impact of microbially‐driven changes in floral scent on the foraging behaviour of the stingless bee Melipona quadrifasciata. Our findings revealed that inoculating tomatoes with PGPR led to an increased number of flowers and enhanced overall floral volatile emission. Additionally, we observed higher flower biomass and pollen levels in all species, except S. peruvianum. Importantly, these changes in volatile emissions influenced the foraging behaviour of M. quadrifasciata significantly. Our results highlight the impact of beneficial soil microbes on plant–pollinator interactions, shedding light on the multiple effects that plant–microbial interactions can have on aboveground organisms.

“…Nevertheless, reproductive barriers, such as self‐incompatibility, sterility and unilateral incompatibility, can be obstacles to the introgression of genes from wild species in commercial tomatoes, reducing the options for interspecific crossings (Peralta & Spooner, 2000; Peralta et al, 2008; Chetelat, 2016). However, some wild tomatoes, such as Solanum pennellii Correl, have shown good compatibility with domesticated tomatoes, allowing gene introgression (Eshed & Zamir, 1995; Resende et al, 2022; Zeist et al, 2021). S. pennellii is a species originated from South America that is able to grow and reproduce in dry and saline soils, being a valuable source for breeding programmes focused on drought tolerance (Iba, 2002; Ramírez‐Ojeda et al, 2021; Solankey et al, 2015).…”

Drought strongly limits tomato yield, and the introgression of genes from wild tomatoes is a powerful tool to obtain drought‐tolerant progenies. The aim of this study was to select drought‐tolerant transgressive progeny obtained from interspecific crosses between drought‐susceptible tomatoes (Solanum lycopersicum) × drought‐tolerant wild species (Solanum pennellii) under in vitro and greenhouse conditions. BC1F2 populations were advanced from backcrosses between F1 × Jumbo AG‐592 (cultivar for fresh consumption) and F1 × BRS Tospodoro (cultivar for industrial processing). For this, BC1F2 seeds were germinated in vitro and evaluated for tolerance to drought. Then, eight genotypes from each BC1F2 were selected and submitted to 14 days of drought (0% of water supply) or well‐watered (100% of water supply) in greenhouse conditions and evaluated for growth, water balance and gas exchanges. Using in vitro assays with mannitol‐induced drought proved to be effective for the initial screening of drought‐tolerant BC1F2 plants, while greenhouse experiments showed that drought decreased photosynthesis in all genotypes, but almost all the BC1F2 progenies had greater photosynthetic capacity, water balance and growth than their commercial parents. As a result, we selected six progenies for fresh consumption and six progenies for industrial processing with increased drought tolerance.
