Summary: In this study, the pollen morphology of subg. Esula Pers. of Euphorbia L. from European Turkey was examined using light and scanning electron microscopy. The pollen grains were found to have trizonocolporate, isopolar, radially symmetrical, medium in size, and oblate spheroidal and suboblate in shape. The ornamentation of the exine was found to be perforate, microreticulate-perforate, microreticulate-perforate with rugulose, or microreticulate-perforate with a heterobrochate pattern. Pollen size, shape, and exine ornamentation have taxonomic importance in species identification, but do not provide strong support for grouping at the sectional level.

Summary: The current study analyzed the epidermal morphology of Asparagaceae in detail and assessed its systematic importance. The study found that at the familial level, no consistent characteristics were found, but anticlinal wall and stomata morphology provided systematic information of different tribes. The study also revealed the linkage of stomata and habitat types and interpreted the intergeneric relationship based on the anticlinal wall and stomata.

Summary: This study investigates the viability of stabilised quarry fines for pavement applications, focusing on the mechanical performance of the materials from mineralogy, microstructure, and chemical composition perspectives. Experimental results show that the element Calcium plays a significant role in the mass variability and increasing the CaO/SiO2 or CaO/(SiO2+Al2O2) ratio leads to improved unconfined compressive strength. Additionally, as curing time increases, more cementitious reaction products are generated, resulting in reduced void to solid ratio and potentially enhancing the unconfined compressive strength.

Summary: The study found that the Fusarium verticillioides cutinase has the ability to degrade rice straw cuticle, with palmitic acid and stearic acid as main products. However, it also showed inhibitory effects on the releasing and producing of sugars, making it not suitable for improving the utilization of agricultural straws.

Summary: The parasitic genus Cuscuta stands out for its unique centromere organization and genome size variations among plants. Monocentric Cuscuta species show a remarkable 102-fold variation in genome sizes, while holocentric species have more moderate sizes. The transition to holocentric chromosomes in Cuscuta is associated with changes in epigenetic marks, chromosome number, and repetitive DNA sequence composition.

Summary: The study investigated the chromosome number, karyotype, and genome size of the Korean lady's slipper orchid, finding that the species is diploid with 2n = 22 and x = 11 as the base chromosome number. The karyotypes were similar among individuals and differentiated the Korean population from the Japanese lady's slipper orchid. Results were consistent with Korean populations being more closely related to Chinese populations than Japanese populations, aiding in the discrimination of Eastern Asian lady's slipper orchid species.

Summary: The transition from monocentric to holocentric organization in Cuscuta was associated with loss or truncation of kinetochore-related genes, disruption of centromeric localization of kinetochore proteins, and degeneration of the spindle assembly checkpoint. This indicates that holocentric Cuscuta species lack a standard kinetochore and do not employ the SAC to control microtubule attachment to chromosomes.
