“…Both results indicated that earlier plant performance contributes to final yield production. It has been proposed that genes are selectively expressed at different growth stages and the genetic control of development at different developmental stages determines to the final yield (Fu et al ., 2022; Zhu, 1995). How these genetic loci are hierarchically regulated and coordinated at different growth stages are largely unknown.…”

SummaryDissecting the genetic basis of complex traits such as dynamic growth and yield potential is a major challenge in crops. Monitoring the growth throughout growing season in a large wheat population to uncover the temporal genetic controls for plant growth and yield‐related traits has so far not been explored. In this study, a diverse wheat panel composed of 288 lines was monitored by a non‐invasive and high‐throughput phenotyping platform to collect growth traits from seedling to grain filling stage and their relationship with yield‐related traits was further explored. Whole genome re‐sequencing of the panel provided 12.64 million markers for a high‐resolution genome‐wide association analysis using 190 image‐based traits and 17 agronomic traits. A total of 8327 marker‐trait associations were detected and clustered into 1605 quantitative trait loci (QTLs) including a number of known genes or QTLs. We identified 277 pleiotropic QTLs controlling multiple traits at different growth stages which revealed temporal dynamics of QTLs action on plant development and yield production in wheat. A candidate gene related to plant growth that was detected by image traits was further validated. Particularly, our study demonstrated that the yield‐related traits are largely predictable using models developed based on i‐traits and provide possibility for high‐throughput early selection, thus to accelerate breeding process. Our study explored the genetic architecture of growth and yield‐related traits by combining high‐throughput phenotyping and genotyping, which further unravelled the complex and stage‐specific contributions of genetic loci to optimize growth and yield in wheat.

“…This paper found also that 10 estimations were negative, occupying up 62.5% of 16 significant epistatic components. Generally, negative epistasis is mainly derived from the interaction of positive QTLs 28 , 29 . Here three QTLs, Ehd1 , Hd3a and Hd1 , carried positive effects, so their epistases appeared mostly negative effects.…”

If there was no gene interaction, the gene aggregation effect would increase infinitely with the increase of gene number. Epistasis avoids the endless accumulation of gene effects, playing a role of homeostasis. To confirm the role, QTL epistases were analyzed by four single-segment substitution lines with heading date QTLs in this paper. We found that QTLs of three positive effects and one negative effect generated 62.5% negative dual QTL epistatic effects and 57.7% positive triple QTL epistatic effects, forming the relationship “positive QTLs-negative one order interactions-positive two order interactions”. In this way, the aggregation effect of QTLs was partially neutralized by the opposite epistatic effect sum. There also were two exceptions, QTL OsMADS50 and gene Hd3a-2 were always with consistent effect directions with their epistases, implying they could be employed in pyramiding breeding with different objectives. This study elucidated the mechanism of epistatic interactions among four QTLs and provided valuable genetic resources for improving heading date in rice.

The grand vision of Frontiers is a world where all people have an equal opportunity to seek, share and generate knowledge. Frontiers provides immediate and permanent online open access to all its publications, but this alone is not enough to realize our grand goals. Frontiers Journal SeriesThe Frontiers Journal Series is a multi-tier and interdisciplinary set of open-access, online journals, promising a paradigm shift from the current review, selection and dissemination processes in academic publishing. All Frontiers journals are driven by researchers for researchers; therefore, they constitute a service to the scholarly community. At the same time, the Frontiers Journal Series operates on a revolutionary invention, the tiered publishing system, initially addressing specific communities of scholars, and gradually climbing up to broader public understanding, thus serving the interests of the lay society, too. Dedication to QualityEach Frontiers article is a landmark of the highest quality, thanks to genuinely collaborative interactions between authors and review editors, who include some of the world's best academicians. Research must be certified by peers before entering a stream of knowledge that may eventually reach the public -and shape society; therefore, Frontiers only applies the most rigorous and unbiased reviews. Frontiers revolutionizes research publishing by freely delivering the most outstanding research, evaluated with no bias from both the academic and social point of view. By applying the most advanced information technologies, Frontiers is catapulting scholarly publishing into a new generation.
