Various reports revealed that chemical constituents from many species of Rubus exhibit diverse biological activities. In this study, a novel flavonoid with a 2-(phenanthren-9-yl)-4H-chromen-4-one structure (1), a 5-phenylthiophene-2-carbaldehyde derivative (5) first isolated from a natural source, together with five known compounds including three ...

In Rosaceae, the replacement of the traditional four-subfamily division (Amygdaloideae or Prunoideae, Maloideae, Rosoideae, and Spiraeoideae) by the three-subfamily division (Dryadoideae, Rosoideae, and Amygdaloideae), the circumscription, systematic position, and phylogeny of genera in Maleae need to be reconsidered. The study aimed to circumscrib...

Lowering the storage temperature is an effective method to extend the postharvest and shelf life of fruits. Nevertheless, this technique often leads to physiological disorders, commonly known as chilling injuries. Apples and pears are susceptible to chilling injuries, among which superficial scald is the most economically relevant. Superficial scal...

The tribe Potentilleae comprises approximately 1700 species in 13 genera, making it one of the largest of the 16 tribes in Rosaceae. Our understanding of the composition and relationships among members of Potentilleae has advanced dramatically with the application of molecular markers in the last two decades. Yet there is still much work remaining ...

Geum japonicum (Rosaceae) has been widely used in China as a traditional herbal medicine due to its high economic and medicinal value. However, the appearance of Geum species is relatively similar, making identification difficult by conventional phenotypic methods, and the studies of genomics and species evolution are lacking. To better distinguish...

The exploration of Cerasus humilis (Bge.) Sok seed shells yielded the identification of six previously uncharacterized compounds, in addition to twelve known compounds. Structure elucidation of these compounds relied on spectroscopic data analysis, and their absolute configurations were established by comparing calculated and experimental electroni...

The exact structure of phloridzin was further confirmed as phloretin 6′-O-glucopyranoside by a single-crystal X-ray diffraction experiment. The distribution changes of phloridzin in flowering, fruitlet, and fruit ripening phases of Malus rockii were quantified by an HPLC with an external standard. The concentrations of phloridzin in leaves, twigs, ...

In this study, the leaf epidermal characters of thirteen taxa of the genera Rosa L. and Rubus L. belonging to the family Rosaceae, which grows naturally in the Kurdistan Region of Iraq, was investigated via light microscopy. All taxa have the type of anomocytic stomata on the abaxial surface, and no stomata are present on the adaxial surface. Withi...
Prunus is an economically important genus widely distributed in the temperate Northern Hemisphere. Previous studies on the genus using a variety of loci yielded conflicting phylogenetic hypotheses. Here, we generated nuclear reduced representation sequencing data and plastid genomes for 36 Prunus individuals and two outgroups. Both nuclear and plas...
Fruits of Fragaria species usually have an appealing bright red color due to the accumulation of anthocyanins, water-soluble flavonoid pigments. Octoploid cultivated strawberry (Fragaria × ananassa) is a major horticultural crop for which fruit color and associated nutritional value are main breeding targets. Great diversity in fruit color intensit...
