Summary: This study investigates the relationship between genome size and endopolyploidy in two pairs of morphologically similar Pulmonaria species. The results show that species with smaller genome sizes tend to have higher levels of endopolyploidy, suggesting that endopolyploidization plays a compensatory developmental role in organs of related species.

Summary: Geophytes are herbaceous plants that regrow from underground buds, playing an important role in plant evolution and ecology. Their ability to adapt to seasonal climates, mediate interactions between plants, and influence macroevolutionary patterns make them valuable research subjects. Despite the importance of belowground organs in characterizing morphological diversity, research on the morphology and evolution of these organs is lacking.

Summary: A three-year study found that malting quality traits and germination were associated with a SNP in the HvMKK3 gene. PHS resistance was genetically correlated with malting quality traits. The study also suggested that PHS susceptibility is beneficial for adjunct brewing, while resistance is compatible with all-malt brewing.

Summary: The study investigated the relationship between genome size and root sprouting ability in herbaceous plants in Central Europe. It found that large-genome species tended to have lower probability of root sprouting ability. However, in a pot experiment, total non-structural and water-soluble carbohydrates were positively related to genome size. Starch was absent in large-genome species, and the link between genome size and carbohydrate storage was less apparent at a small phylogenetic scale.

Summary: Minimal residual disease (MRD) evaluation by multiparameter flow cytometry (MFC) at 3 months after first-line therapy completion in newly diagnosed AL amyloidosis patients is feasible and associated with improved organ response rates and longer progression-free survival (PFS) over a long follow-up period.

Summary: The significant variation of genome size in land plants is associated with different adaptive features. Flow cytometry is commonly used for estimating C-values but performs poorly on herbarium materials. This study demonstrates the potential use of herbarium spores for estimating C-values of fern plants, even from older specimens, and reveals important findings on genome downsizing and apomixis.

Summary: Previous studies suggested that holocentric chromosomes may provide a selective advantage in high UV-B radiation, aiding in terrestrialization, and the research found that holocentric plants are less stressed by UV-B at higher elevations compared to monocentric plants.

Summary: The centromere drive model explains an evolutionary process caused by centromeric repeats expansion, resulting in preferential segregation of an expanded centromere. The histone protein CenH3 plays a key role in adaptive evolution to counter the detrimental effects of centromere drive. Holocentric chromosomes may prevent centromere drive through their unique kinetochore structure.

Summary: Flow cytometry (FCM) is widely used in establishing nuclear DNA content in plants, with a variety of applications in plant science. This paper discusses the advantages and limitations of FCM in determining plant ploidy, genome size, DNA base composition, and provides recommendations on obtaining accurate and reliable results, as well as troubleshooting guidance.

Summary: The study found that genome size is a strong predictor of total centromere size in Eukaryotes, regardless of phylogenetic relatedness and centromere type. This implies a common mechanism maintaining stable total centromere size across Eukaryotes.

Summary: This study reveals a positive relationship between kinetochore and chromosome size in eukaryotes, suggesting that the observed scaling of kinetochore size to genome size may be influenced by the mechanics of cell division. The potential causal link between kinetochore and chromosome size indicates that evolutionary mechanisms, such as centromere drive, could play a role in chromosome and genome size evolution.

Summary: Having different number of genome copies affects transcription and metabolite production in plants. This study investigated the effect of haploidy on flavonoid content in ginkgos by measuring the flavonoid content in leaves of haploid and diploid grafted plants and analyzing their transcriptomes and proteomes. Haploids had smaller leaves and lower flavonoid content compared to diploids. The downregulation of key genes involved in flavonoid biosynthesis regulation may contribute to the lower flavonoid content in haploids.

Summary: Using molecular and morphological evidence, we confirmed the monophyly of Cirsium sect. Eriolepis and proposed to treat it as a separate genus. We also segregated Cirsium italicum into a separate genus based on molecular and morphological data, and published the name of a new hybrid genus. A total of 129 new combinations were proposed.

Summary: This study investigates genome and mean chromosome size in the cyperid clade and reveals that cyperids have the smallest mean chromosome size in seed plants, with a large divergence between the smallest and largest values. It is found that cyperid species with smaller chromosomes have larger geographical distributions, and there is a strong inverse association between mean chromosome size and number in this lineage.

Summary: Polyploid plants have enlarged stomata but these do not disadvantage them in low CO2 concentrations and may even contribute to their faster growth. Higher polyploids with large genomes also have increased operational stomatal conductance and lower water-use efficiency.

Summary: We studied the populations of Cirsium bertolonii in different locations and identified individuals that showed morphological shifts towards co-occurring C. acaulon or C. erisithales. These intermediate individuals were confirmed to be hybrids through various methods. The genetic erosion caused by interspecific hybridization poses a risk to the genetic integrity of C. bertolonii and other narrowly endemic high-mountain Cirsium species in Europe.
