Murine cardiomyocytes undergo proliferation, multinucleation, and polyploidization during the first 3 weeks of postnatal life, resulting in a mixture of diploid and tetraploid cardiomyocytes in the heart. Understanding the molecular differences between diploid and tetraploid cardiomyocytes from these processes has been limited due to lack of unique markers and their heterogenous origins. Here, we apply single-nucleus RNA-sequencing to fluorescence-activated cell sorting-selected diploid and tetraploid cardiomyocytes to characterize their heterogeneity and molecular distinctions. For complete details on the use and execution of this protocol, please refer to Cui et al. (2020).

Hybrid potato breeding based on diploid inbred lines is transforming the way of genetic improvement of this staple food crop, which requires a deep understanding of potato domestication and differentiation. Here, we resequenced 314 diploid wild and landrace accessions to generate a variome map of 47,203,407 variants. Using the variome map, we discovered the reshaping of tuber transcriptome during potato domestication, characterized genome-wide differentiation between landrace groups Stenotomum and Phureja, and identified a jasmonic acid biosynthetic gene possibly affecting tuber dormancy period.

Proline, a critical osmoregulatory compound, is integral to various plant stress responses. The gene, which encodes the rate-limiting enzyme in proline biosynthesis, known as ∆1-pyrroline-5-carboxylate synthetase, is fundamental to these stress response pathways. While the functions of genes in plants have been extensively documented, their specific roles in cotton remain inadequately characterized.

Polyploidy is a powerful mechanism driving genetic, physiological, and phenotypic changes among cytotypes of the same species across both large and small geographic scales. These changes can significantly shape population structure and increase the evolutionary and adaptation potential of cytotypes. , an edaphic steno-endemic species with a narrow distribution in the Balkan Peninsula, serves as an intriguing case study.

Whole genome duplication (WGD) is a powerful evolutionary mechanism in plants. Autopolyploids have been comparatively less studied than allopolyploids, with sexual autopolyploidization receiving even less attention. In this work, we studied the transcriptomes of neotetraploids (2n = 4x = 32) obtained by crossing two diploid (2n = 2x = 16) plants of Medicago sativa that produce a significant percentage of either 2n eggs or pollen.

Haplotyped-resolved phased assemblies aim to capture the full allelic diversity in heterozygous and polyploid species to enable accurate genetic analyses. However, building non-collapsed references still presents a challenge. Here, we used long-range interaction Hi-C reads (high-throughput chromatin conformation capture) and HiFi PacBio reads to assemble the genome of the apomictic cultivar Basilisks from Urochloa decumbens (2n = 4x = 36), an outcrossed tetraploid Paniceae grass widely cropped to feed livestock in the tropics.
