“…This result differs from past studies where soybean seed protein content was reported to either decrease (Hao et al., 2014; Li et al., 2018; Soares et al., 2019, 2021) or stay unchanged (Fiscus et al., 2007; Jin et al., 2017). Lower protein content at eCO 2 has been observed in chickpeas (Lamichaney et al., 2021; Saha et al., 2015), rice (Uprety et al., 2010; Yang et al., 2007), wheat (Fernando, Panozzo, Tausz, Norton, Fitzgerald, & Seneweera, 2012; Uprety et al., 2010; Wu et al., 2004), and other grasses (Barbehenn et al., 2004) and appears to be the rule rather than the exception in C 3 crops. However, legumes may be more resilient than other C 3 crops because of their potential for biological nitrogen fixation (Campo et al., 2009; Taub et al., 2008; Zimmer et al., 2016).…”

“…Over the last decade, many studies have described altered grain composition for plants grown under elevated [CO 2 ] (eCO 2 ). In particular, C 3 crops had lower protein content (Lamichaney et al., 2021; Taub et al., 2008; Yang et al., 2007) as well as decreased calcium (Ca), iron (Fe), and zinc (Zn) when grown at eCO 2 (Loladze, 2014; Myers et al., 2014). Reductions in macro‐ and micronutrients could threaten food security, especially in communities already facing malnutrition.…”

Reduced grain and seed nutrient content in crops grown under elevated CO2 concentrations (eCO2) have raised concerns about future food security. Studies have reported that different seed elements responded differently to eCO2. Additionally, the nutrient response to eCO2 varied across species and cultivars. This study investigated the response of seed quality in two soybean cultivars (HS93‐4118 and Loda) previously shown to have different yield responses to eCO2. We show that seed quality responded differently to eCO2 for the two cultivars and that elements were differentially impacted. The strongest declines under eCO2 were observed for Al, Ca, Fe, and Se while P and Mn were unaffected. Seed protein content increased under eCO2 for the two cultivars. Oil content, however, showed a negative relationship with yield and declined under eCO2. Using path analysis, we show that eCO2 reduced the seed content for some elements through increasing seed yield, effectively diluting the elemental concentrations, while other elements were reduced in a yield‐independent manner. Despite the decline in the seed concentration for some elements, the overall yield per hectare of elements, protein, and oil under eCO2 increased because of greater seed yield. We quantified the economic impact of altered seed composition and show that the decline in oil content with increasing soybean yield at eCO2 could adversely impact profits.

“…In our study, growth traits such as achenes per plant and seeds per plant, and seed weight decreased under high temperature (35 °C) and continuous light (24 h d -1 ), which can be attributed to a decline in chlorophyll concentrations and uptake of CO 2 availability for photosynthesis [ 69 ]. Numerous studies have shown a rise in the uptake of CO 2 during photosynthesis stimulates carbohydrates accumulation in leaves [ 38 , 70 ]. The transportation of carbohydrates from the source (leaf) to the sink (seed) has a crucial pattern in the growth and development of seeds [ 71 ].…”

“…However, the susceptibility of seed vigor to elevated CO 2 appears dependent on the species. For example, in a chickpea study, elevated CO 2 concentrations (566-630 ppm) did not affect seed vigor (Lamichaney, Tewari, et al 2021). Additional work is necessary to determine whether elevated CO 2 levels could impact seed vigor more prominently in combination with other factors.…”

Seed germination and vigor: ensuring crop sustainability in a changing climate

2022

In the coming decades, maintaining a steady food supply for the increasing world population will require high-yielding crop plants which can be productive under increasingly variable conditions. Maintaining high yields will require the successful and uniform establishment of plants in the field under altered environmental conditions. Seed vigor, a complex agronomic trait that includes seed longevity, germination speed, seedling growth, and early stress tolerance, determines the duration and success of this establishment period. Elevated temperature during early seed development can decrease seed size, number, and fertility, delay germination and reduce seed vigor in crops such as cereals, legumes, and vegetable crops. Heat stress in mature seeds can reduce seed vigor in crops such as lettuce, oat, and chickpea. Warming trends and increasing temperature variability can increase seed dormancy and reduce germination rates, especially in crops that require lower temperatures for germination and seedling establishment. To improve seed germination speed and success, much research has focused on selecting quality seeds for replanting, priming seeds before sowing, and breeding varieties with improved seed performance. Recent strides in understanding the genetic basis of variation in seed vigor have used genomics and transcriptomics to identify candidate genes for improving germination, and several studies have explored the potential impact of climate change on the percentage and timing of germination. In this review, we discuss these recent advances in the genetic underpinnings of seed performance as well as how climate change is expected to affect vigor in current varieties of staple, vegetable, and other crops.
