“…Conesa et al [ 50 ] performed a climatic classification of 14 of the wild and related species to S. lycopersicum based on the mean value of annual precipitation and temperature and the De Martonne index. These authors proposed the formation of three groups: species from humid regions ( S. ochranthum , S. neorickii , S. chmielewskii , S. juglandifollium and S. lycopersicum ), species from semi-arid sites ( S. arcanum , S. habrochaites , S. pimpinelifollium , S. galapagense, and S. chesmaniae ) and species from arid regions ( S. sitiens , S. chilense , S. lycopersicoides , S. penneellii , and S. peruvianum ).…”

Conservation and sustainable use of species diversity require a description of the environment where they develop. The objectives were to determine ecological descriptors and climatic diversity of areas along the distribution range of 12 species of wild tomatoes (Solanum sect. Lycopersicon) and four wild species of phylogenetically related groups (Solanum sect. Juglandifolia and sect. Lycopersicoides), as well as their ecological similarity in Latin America. With 4228 selected tomato accessions and an environmental information system (EIS) composed of 21 climatic variables, diversity patterns of the distribution areas were identified for each species, as well as ecological descriptors through the use of geographic information systems (GIS). The contribution of climatic variables to the species geographical distribution was identified by principal component analysis (PCA), and similarity in species distribution as a function of the variables identified with cluster analysis (CA). Climatic characteristics and the environmental amplitude of wild tomatoes and related species along their distributional range were satisfactorily determined by ecological descriptors. Eleven climate types were identified, predominantly BSk (arid, steppe, cold), BWh (arid, desert, hot), and Cfb (temperate, no dry season, warm summer). PCA determined 10 most important variables were the most important for the geographical distribution. Six groups of species were identified according to CA and climatic distribution similarity. This approach has shown promissory applications for biodiversity conservation of valuable genetic resources for tomato crop breeding.

“…This species‐specific response of RGR is consistent with previous studies that focused on individual crops. For example, RGR increased with domestication in tomato (Conesa et al ., 2017), decreased in rice (Cook & Evans, 1983) and barley (Chapin et al ., 1989), but showed no effect in wheat (Evans & Dunstone, 1970), maize (Duncan & Hesketh, 1968) and millet (Evans & Bush, 1985). These studies were conducted under dissimilar conditions and with different methodologies.…”

Disparities among crop species in the evolution of growth rates: the role of distinct origins and domestication histories

et al. 2021

Growth rates vary widely among plants with different strategies. For crops, evolution under predictable and high-resource environments might favour rapid resource acquisition and growth, but whether this strategy has consistently evolved during domestication and improvement remains unclear.Here we report a comprehensive study of the evolution of growth rates based on comparisons among wild, landrace, and improved accessions of 19 herbaceous crops grown under common conditions. We also examined the underlying growth components and the influence of crop origin and history on growth evolution. Domestication and improvement did not affect growth consistently, that is growth rates increased or decreased or remained unchanged in different crops. Crops selected for fruits increased the physiological component of growth (net assimilation rate), whereas leaf and seed crops showed larger domestication effects on morphology (leaf mass ratio and specific leaf area). Moreover, climate and phylogeny contributed to explaining the effects of domestication and changes in growth.Crop-specific responses to domestication and improvement suggest that selection for high yield has not consistently changed growth rates. The trade-offs between morphophysiological traits and the distinct origins and histories of crops accounted for the variability in growth changes. These findings have far-reaching implications for our understanding of crop performance and adaptation.

“…Physiological traits seemingly play a more important role in determining high rates of leaf growth than morphological features, with domesticated tomatoes being more impacted by the variance in these traits than wild tomatoes (Conesa et al, 2017). Thus, we investigated leaflet physiology in M82, S. pennellii , and introgression lines (ILs) harbouring S. pennellii genomic fragments.…”

Cells, tissues, and organs are characterized by harbouring complex systems allowing communication between one another. Plant domestication was demonstrated to have structured the circadian rhythms, while also synchronising flowering and metabolism. Here, we demonstrate that the domesticated tomato (Solanum lycopersicum) manifests more synchronized rhythmicity across the whole plant. Consequently, the leaf development program is more coordinated in this species than in its wild relatives, wherein S. lycopersicum young leaves develop slowly in comparison to mature leaves. Young leaves from wild tomatoes display higher photosynthesis than mature leaves, while large metabolite accumulations occur across plant segments. Consequently, the diel metabolite levels are rather similar between young and mature leaves in the wild tomato S. pennellii, whereas the expression patterns for circadian clock genes are widely contrasting between both leaves. We further demonstrated that additions of genes related to domestication into the wild tomato S. pimpinellifolium appear to synchronize the development of young and mature leaves to be rather similar to that observed for S. lycopersicum. Collectively, the strengthening of inter-organs relationships on domesticated tomato indicates a synchronized biology, which is most likely fundamental to explaining its elevated yield
