Summary: This study evaluated the utility of four candidate DNA barcoding regions in seven genera of Gramineae. It found that matK and ITS showed the highest discriminatory power, while rbcL and trnL-F were less effective. The study also demonstrated the feasibility of establishing a technical system for rapid and reliable identification of these seven genera, and provided crucial reference for analyzing the genetic diversity of grass germplasm resources.

Summary: The morphology, ultrastructure, and phylogeny of eight soil diatom strains assigned to the Pinnularia genus were studied, with six new species identified and described for the first time. Molecular phylogeny reconstruction grouped the new strains with different subclades within Pinnularia. Fatty acid profiles of the algae cultured on specific medium showed high yields of saturated and monounsaturated fatty acids, making the novel Pinnularia strains promising feedstock for biofuel production.

Summary: The study focuses on the taxonomic position of Codonoblepharon and its phylogenetic relationships within Orthotrichoideae. Based on phylogenetic reconstruction using four different loci, it is confirmed that Codonoblepharon belongs to a separate lineage and a new tribe, Codonoblepharonteae, is proposed.

Summary: This study investigates the phylogenetic relationships of Indian Daphne species based on nuclear and plastid sequences. The results support the monophyly of the genus Daphne and reveal two major well-supported clades. The study also confirms the relationship between the narrow endemic species D. thanguensis and the morphologically similar D. tangutica, and supports the independent species status of D. retusa and D. tangutica.

Summary: During the revision of the genus Syntrichia, we found issues with the description of certain species and their relationship with other related genera. Through phylogenetic analysis and examination of morphological features, we were able to establish a more accurate understanding of the genus and propose revisions and new suggestions.

Summary: A new species of Fredericqia from the Choshi Peninsula, Japan has been described based on morphological and molecular analyses, with unique characteristics such as a flattened incurved thallus and marginal proliferations. Molecular analysis indicates that this new species, named Fredericqia chiharae, belongs to the genus Fredericqia and is distinct from other species within the genus.

Summary: The study identified a deep-water species of Rhodymenia prostrata as a new species in the genus Halopeltis, which was named Halopeltis tanakae. This new species, characterized by specific anatomical features, was found in the northwestern Pacific and represents the second species of the genus in the region.

Summary: This study aims to develop a DNA reference library of Indonesian banana species, varieties and cultivars to understand genetic relationships and reconstruct phylogenetic trees. Three barcoding markers (rbcl, matK and trnL-F) were used to differentiate among A and B genomes. The rbcL marker can only distinguish at the genus level, while matK and trnL-F can be used at species level.

Summary: A new species, Curculigo konkanensis, is described from Maharashtra, India, and it is closely related to C. brevifolia and C. orchioides but differs in various characteristics. Cytological parameters, karyotype formula, and DNA analysis support the distinction of C. konkanensis, C. brevifolia, and C. orchioides. Plastid DNA data places the new species in the Curculigo orchoides subclade and shows its phylogenetic affinity with Curculigo brevifolia.

Summary: The study found that there is only one species of freshwater Hildenbrandia in Japan, which is H. japananensis, and it is the same species as the one found in China. It is suggested to merge H. jigongshanensis with H. japananensis taxonomically and further research is recommended on Asian freshwater Hildenbrandia.

Summary: The importance of diatoms in bioindication and palaeolimnology is significant, and a comprehensive understanding of their morphological variability is essential for species identification and applications in these fields. This study investigated the differences in valve morphology between solitary and colonial cultures of centric diatom genera Cyclostephanos and Stephanodiscus. The results showed that colony formation affects not only the spine morphology but also other morphological features of the valve. The study also suggests that certain species may be morphotypes or colony forms of the same species, which has implications for taxonomy and future research on morphological changes due to colony formation in other groups and taxa.

Summary: The study compared Scapania metahimalayana, S. koponenii, S. pseudojavanica, and S. stephanii using morphological and molecular genetic methods, confirming their separation at the species level and identifying key distinguishing characteristics. This research highlighted the importance of combined morphological and molecular studies for accurately identifying different species within the same genus.
