“…Parallel comparisons of allelic frequency of Tof11 and Tof12 and other established soybean domestication genes indicate that a change in reproductive timing accompanied previously documented changes in dormancy and seed dispersal during domestication. Domestication-related changes in soybean flowering time support previous studies focusing on hard seededness, seed dormancy, seed coat shininess, and pod shattering traits (Dong et al 2014;Sun et al 2015;Wang et al 2018;Zhang et al 2018), demonstrating that selection for the early-flowering tof12-1 allele broadly coincided with selection for alleles at the Hs1-1, G, and Shat1-5 loci. Although broad discussions of plant domestication have often included flowering phenology as a prominent component of domestication syndrome, and highlighted in particular the importance of early, synchronous maturity, there are few cases clearly demonstrating changes in phenology during domestication, and even fewer in which the molecular basis has been conclusively defined.…”

Flowering time variation in soybean is well characterized within domesticated germplasms and is critical for modern production, but its importance during domestication is unclear. Recently, Lu et al. (Nature Genetics, 2020) reported that two homeologous pseudo‐response‐regulator genes, Tof12 and Tof11, were sequentially selected in early soybean evolution for ancient flowering time adaptation and intensification of crop cultivation.

“…Genetic variation has been studied in many species by crossing genotypes with different dormancy levels, followed by the analysis of their progeny and parallel selection for seed dormancy [33,35,36]. The analysis of association patterns among morphological seed traits, mineral elements and germination parameters revealed significant negative correlations between seed size (i.e.…”

Origin-dependence of variation in seed morphology, mineral composition and germination percentage in Gynandropsis gynandra (L.) Briq. accessions from Africa and Asia

Background: Spider plant [Gynandropsis gynandra (L.) Briq.], an economically promising African leafy vegetable, characterized for leaf yield components and nutritive quality, exhibits poor seed germination that hinders a wider expansion of the crop in urban and periurban horticultural systems. So far, there is little information pertaining to seed morphological traits and mineral elements content that may be associated with higher seed germination. This research investigated the hypothesis that spider plants from different geographical areas exhibited differences in seed mineral composition, morphological traits, and germination capacity. To this end, twenty-nine accessions of Gynandropsis gynandra from West and East-Southern Africa, and Asia were screened for variation in seed size (area, perimeter, length, width), 10-seed weight, mean germination time, germination percentage and mineral content variations. The scanning electron microscopy (SEM), light microscopy and energy dispersive spectroscopy (EDS) solution were used to study seed morphology and mineral composition. Results: We show for the first time the external and internal structure of the seeds of Gynandropsis gynandra and measured eight mineral elements, including carbon (C), oxygen (O), magnesium (Mg), aluminium (Al), phosphorus (P), sulphur (S), potassium (K) and calcium (Ca). The accessions differed significantly (p < 0.001) with respect to seed size (area, perimeter, length, width), 10-seed weight, mean germination time and germination percentage. The hierarchical cluster analysis based on fourteen variables grouped the accessions into three distinct clusters, partially dependent on their geographical origin. Asian accessions exhibited smaller seeds and recorded higher values in terms of germination percentage. West African accessions had bigger seeds but with lower germination percentage. Variation in minerals such as potassium, carbon, and calcium content showed different patterns according to geographical origins.(Continued on next page)
