Plant pan-genomics and its applications

Junpeng Shi et al.

Summary: Plant genomes are highly diverse and most genomic sequences are not shared among individuals. Variable DNA sequences and conserved core sequences form a more sophisticated pan-genome, representing all non-redundant DNA in a species. Advances in genome sequencing technologies have accelerated plant pan-genomics research. This review focuses on driving forces of structural variations, methodological innovations, and major successes in constructing plant pan-genomes. Efforts are also summarized towards decoding dark matter in telomere-to-telomere or gapless plant genomes. These new genome resources are expected to become new references for genetic studies and plant breeding.

Wheat breeding history reveals synergistic selection of pleiotropic genomic sites for plant architecture and grain yield

Aili Li et al.

Summary: Diversity surveys of crop germplasm can provide insights into the genomic basis for plant architecture and grain yield improvement. In this study, exome sequencing of 287 wheat accessions revealed the presence of selective sweeps between landraces and cultivars, which contain genes known for yield improvement. Genome-wide association study identified genetic loci associated with yield potential and characterized two underlying genes that regulate plant height and grain weight. Additionally, the study proposed a working model for historical wheat breeding based on the interaction between these genes and a classical plant height locus.

Harnessing Knowledge from Maize and Rice Domestication for New Crop Breeding

Qiuyue Chen et al.

Summary: This study provides a comprehensive summary of the domestication processes of maize and rice, highlighting their genetic solutions and distinct regulatory and evolutionary mechanisms. It discusses how knowledge from past domestication processes can be used with emerging technologies to improve modern crop breeding and domesticate new crops to meet increasing human demands.

FRIZZY PANICLE defines a regulatory hub for simultaneously controlling spikelet formation and awn elongation in bread wheat

Dejie Du et al.

Summary: The TRS trait in Zang734 wheat variety is caused by a null mutation in WFZP-A and deletion of WFZP-D, with WFZP playing a dual role in simultaneously repressing spikelet formation and activating awn development genes. This study provides insights into how WFZP suppresses spikelet formation while promoting awn elongation, defining WFZP-D as a favorable gene for high-yield crop breeding.
