Summary: Genome size and cell size in frogs are strongly correlated, and this correlation affects developmental rate. However, it is unclear how the relationship between cell size and ploidy is established during embryonic development. By studying different polyploid frogs, researchers discovered that cell size is primarily determined by egg size, while nuclear size is correlated with genome size. At the subcellular level, nuclear size is more strongly correlated with genome size, while mitotic spindle size scales with cell size. These findings demonstrate the relationship between cell size and ploidy in frogs and reveal different size scaling mechanisms during embryogenesis, suggesting that Xenopus development is consistent across a wide range of genome and egg sizes.

Summary: The study revealed that the mortality rate due to food competition in ant communities in forests showed a hump-shaped trend with temperature, with interspecific competition leading to higher mortality than intraspecific competition. In dominant species, mortality due to intraspecific competition was higher, while subordinate species saw an increase in intraspecific competition mortality as interspecific competition decreased. Temperature, density of other species, and species characteristics such as body size, dominance, feeding strategy, and aggressiveness were all factors associated with mortality due to competition for food.

Summary: Genomic imprinting causes biased expression of maternally and paternally inherited alleles in the triploid endosperm of flax, with a total of 248 candidate imprinted genes identified. These imprinted genes are not well conserved among plant species and contribute to intraspecific variation in flax, with some undergoing positive selection during domestication. Imprinted genes related to flax functions, including seed size and weight, were found to have undergone positive selection and could provide insights into the function and genomic variation of imprinted genes in the flax population.

Summary: Phytoremediation using hyperaccumulators is a popular and environmentally-friendly clean method. Long-term continuous testing is crucial due to its low efficiency during the growth period. An experiment using Cd hyperaccumulator Rorippa globosa was conducted over a 3-year period to investigate the effect of two remediation modes on continuous efficiency. The results showed that biomass was higher in maturity-harvest treatments, while shoot Cd concentrations were lower in flowering-harvest treatments. However, Cd phytoextraction efficiency was higher in the flowering-harvest treatments due to the shorter growth cycle. After three years of R. globosa phytoextraction, the concentration of extractable Cd decreased and corresponding phytoextraction efficiencies were lower. It is suggested that cultivation modes and rotation with low-accumulation crops, or three times flowering harvests per year, could be practical solutions.

Summary: In this study, the nuclear morphology and chromosome organization in cycling and endoreduplicated nuclei of barley seeds were analyzed. It was found that endoreduplicated nuclei have an irregular shape, reduced sister chromatid cohesion, and decreased centromeric histone CENH3. While the chromosomes initially have a Rabl configuration, the organization is lost and intermingled in endoreduplicated nuclei with increasing endoreduplication. This suggests that mitotic divisions play a role in introducing and reinforcing Rabl configuration in a tissue- and seed age-dependent manner.

Summary: Arabidopsis arenosa is a promising candidate for phytoremediation due to its high tolerance and accumulation ability. In this study, octaploid specimens were obtained through indirect organogenesis, resulting in higher biomass and improved capacity for heavy metal accumulation and translocation. The fully fertile octaploids exhibited larger cell and organ size compared to tetraploid regenerants and initial plants. These promising results indicate that the obtained polyploids could be used in the future for phytoremediation of metal-contaminated areas.

Summary: The study aimed to investigate the impact of salinity and pH variations on cadmium uptake by Bidens tripartita L. roots using non-invasive micro-test technology (NMT). The results showed that Cd2+ influx in the roots decreased when treated with Cd and 5 mM or 10 mM NaCl, compared to Cd stress alone. However, Cd and 2.5 mM NaCl had minimal effect on net Cd2+ influx. Notably, Cd treatments with pH = 4.0 significantly increased Cd2+ influx, while pH = 7.0 significantly decreased it compared to pH = 5.5. Additionally, Cd treatments with 5 mM or 10 mM NaCl reduced chlorophyll concentrations in leaves and root vigor, while Cd treatments with 2.5 mM NaCl showed no significant differences. A higher root vigor was observed in Cd treatments with pH = 4.0 compared to pH = 5.5.

Summary: The present study characterized a diverse collection of purple and non-purple carrot accessions for their concentration of anthocyanins, phenolics, carotenoids, and antioxidant capacity. Significant variation was found among the accessions, with acylated anthocyanins being the most dominant pigment. Purple carrots exhibited higher levels of anthocyanins, phenolics, and antioxidant capacity compared to non-purple carrots. Antioxidant capacity was positively correlated with anthocyanin content and total phenolic content, but not with carotenoids. Certain accessions were identified as potential sources for food dyes or increased nutraceutical value.

Summary: This study used an improved carrot reference genome and resequencing data from 630 carrot accessions to investigate the domestication and improvement of carrots. The findings suggest that carrot was domesticated during the Early Middle Ages in western Asia to central Asia, and orange carrot was selected during the Renaissance period, possibly in western Europe. The study also identified genes related to circadian clock/flowering and carotenoid accumulation that were under selection during domestication and improvement. Three recessive genes were found to be essential for selecting the high alpha- and beta-carotene orange phenotype. These genes regulate carotenoid accumulation through molecular mechanisms involving the carotenoid biosynthetic pathway, the photosynthetic system, and chloroplast biogenesis. Overall, this study provides insights into the domestication and breeding history of carrots and the genetics of carotenoid accumulation.

Summary: Bagging is a crucial cultivation measure that affects the quality of peach fruit by regulating exposure to light. This study investigated the effects of bagging on the content of phenolic compounds in peach fruit and identified the most sensitive compounds to bagging treatment. The study also explored the regulatory role of bagging on phenolic synthetic-related genes. The results showed that bagging affected the accumulation of different phenolics in different peach cultivars and light intensity played a significant role in the accumulation of anthocyanins and other phenolic substances in peach fruit. Additionally, the expression of structural genes and transcription factors related to phenolic synthesis was regulated by bagging and light conditions. These findings provide a foundation for understanding the regulation mechanism of light on the synthesis of phenolic compounds in peach fruit.
