“…HS, also known as physical dormancy, seed coat-imposed dormancy, or "stone" or "impermeable" seeds, has been found in ~15 angiosperm families, of which the Leguminosae is the largest (Meyer et al, 2007;Baskin and Baskin, 2014;Paulsen et al, 2014;Wen et al, 2024). In contrast, seeds that are prone to water absorption are termed "soft" or "permeable" seeds.…”

Soybean is one of the world’s most economically significant crops and is widely utilized as an essential source of vegetable protein and edible oil. Cultivated soybean is domesticated from its annual counterpart, wild soybean, which is considered valuable germplasm for soybean breeding. However, wild soybean accessions generally produce seeds with impermeable coats, a trait known as hard seededness (HS), which is beneficial for long-term seed survival but is undesirable for the uniform water absorption and germination of seeds, thus limiting the utilization of wild soybeans in breeding. In addition, moderate HS can isolate the embryo from the surrounding environment and is thus beneficial for long-term seed storage and germplasm preservation. The HS trait is primarily associated with the structure and chemical composition of the seed coat. Moreover, its development is also influenced by various environmental conditions, such as water and temperature. Genetic analysis has revealed that HS of soybean is a complex quantitative trait controlled by multiple genes or minor quantitative trait loci (QTL), with many QTLs and several causal genes currently identified. Investigating the physiological and molecular mechanisms underlying this trait is crucial for soybean breeding, production, and food processing. For this article, the literature was reviewed and condensed to create a well-rounded picture of the current understanding of internal and external factors, QTLs, causal genes, and the regulatory mechanisms related to the HS of soybean, with the aim of providing reference for future research and utilization of this trait.

Gene expression in individual germinated seeds of four different soybean (Glycine max [L.] Merr.) cultivars, GL3494, OAC Kent, Williams 82, and Jackson, was examined using single seed high-throughput RNA sequencing (ssRNA-seq). The gene expression was similar between two individual seeds of the same cultivar, but different among individual seeds of the four cultivars. Notably, ssRNA-seq identified five genes that were not stably expressed in Williams 82, having either no detectable sequence reads or less than five sequence reads mapped to the exon regions of chromosomes in Williams 82. These findings were validated by reverse transcription polymerase chain reaction analysis. The study’s results demonstrate that gene expression in germinated seeds is unique to an individual seed from each soybean cultivar. This uniqueness may affect composition and content of nutrients in germinated soybeans used as food ingredients.

Seed physical dormancy (hard-seededness) is an interesting ecological phenomenon and important agronomic trait. The loss of seed coat impermeability/hard-seededness is a key target trait during the domestication of leguminous crops which allows seeds to germinate rapidly and uniformly. In this study, we examined the mutation of quantitative trait locus (QTL) genes, GmHs1-1 and GmqHS1, in 18 wild soybean (G. soja) and 23 cultivated soybean (G. max) accessions. The sequencing results indicate that a G-to-T substitution in GmqHS1 and a C-to-T substitution in GmHs1-1 occurred in all 23 cultivated soybean accessions but not in any of the 18 wild soybean accessions. The mutations in the two genes led to increased seed coat permeability in cultivated soybean. Therefore, we provide evidence that two genes, GmHs1-1 and GmqHS1, simultaneously contribute to the domestication of hard-seededness in soybeans. This finding is of great significance for genetic analysis and improved utilization of the soybean hard-seededness trait.
