  • Recent herbarium reexamination and field studies yielded two monocotyledonous plant taxa of the family Poaceae that could be documented in the national inventory list of species of Korea. These species, collected from Jeollabuk-do and Gyeongsangnam-do, were introduced and naturalized in Korea. Two species were identified as Holcus mollis L. and Aira elegantissima Schur. We provided the descriptions and descriptive photos of these species. Keys to the newly recorded species and related taxa were also provided.

  • This study was conducted to obtain the basic information of edible resources among plant species. Potentials of resource plants were important in various usages, healthy food, medicinal materials, and breeding materials. Through our investigation 609 species of resources plants were considered as edible resources. These species belong to 74 families in which Asteraceae, Poaceae, Fabaceae, and Rosaceae were major families. Brassicaceae, Liliaceae, and Asteraceae contained large numbers of edible plants because plants belonged to these families were mainly used as vegetable. But Cyperaceae and Poaceae had relatively small numbers of species in the category of edible plant because plants belonged to these families have not been used directly as vegetables, common usage of edible plant. But Poaceae have a potentials as genetic donor for resistance-breeding strategies in major cereals. Although Poaceae can not be used as food directly, Poaceae should be investigated intensely in future for improvement of major cereals or application as fodder plants. The beneficial traits of edible plants as breeding materials have not been studied yet and development of new crop from plant resources requires the information about current situation in occurrence of resources plants genetically related to current crop species. Our results do not cover all plant species in Korea but this classification and identification about edible resources will provide primary information about plant resources. The collected seeds of resource plants showed wide spectrum in germination rate among plant species. The germination rate would probably be affected by collecting times, collected stage, and stored period. The proper methods about improving germination rate have to be elucidated to propagate the resource plants.

  • This study was conducted to clarify the phylogenetic position and relationships of Korean Poaceae taxa. A total of 438 taxa including 155 accessions of Korean Poaceae (representing 92% and 72% of Korean Poaceous genera and species, respectively) were employed for phylogeny reconstruction. Sequence data of eight chloroplast DNA markers were used for molecular phylogenetic analyses. The resulted phylogeny was mostly concordant with previous phylogenetic hypotheses, especially in terms of subfamilial and tribal relationships. Several taxa-specific indels were detected in the molecular phylogeny, including a 45 bp deletion in rps3 (PACMAD [Panicoideae, Arundinoideae, Chloridoideae, Micrairoideae, Aristidoideae, Danthonioideae] clade), a 15 bp deletion in ndhF (Oryzeae + Phyllorachideae), a 6 bp deletion in trnLF (Poeae s.l.), and two (17 bp and 378 bp) deletions in atpF-H (Pooideae). The Korean Poaceae members were classified into 23 tribes, representing eight subfamilies. The subfamilial and tribal classifications of the Korean taxa were generally congruent with a recently published system, whereas some subtribes and genera were found to be non-monophyletic. The taxa included in the PACMAD clade (especially Andropogoneae) showed very weak and uncertain phylogenetic relationships, presumably to be due to evolutionary radiation and polyploidization. The reconstructed phylogeny can be utilized to update the taxonomic positions of the newly examined grass accessions.

  • Two unrecorded Poaceae species, Anthoxanthum glabrum and Saccharum arundinaceum, are herein newly reported from Korea. Anthoxanthum glabrum (Ae-Gi-Hyang-Mo) was found in Ansan-si, Gyeonggi-do, Sangju-si, Gyeongsangbuk-do and Hwasun-gun, Jeollanam-do. It is distinguished from A. nitens by the length of its spikelet, glume and lemma. Saccharum arundinaceum (Keun-Gae-Sa-Tang-Su-Su) was found in Mapo-gu, Gangnam-gu, Seoul, and Hwasun-gun, Jeollanam-do. It is distinguished from S. spontaneum by hair on the lower glume and according to the length of the hair on the callus of its spikelet. In this study, a description and illustrations of the species and photos of the habitat are provided.

  • A new species, Miscanthus wangpicheonensis of section Kariyasua, is described and illustrated from the morphological characteristics based on a type specimen collected from Gyeongsangbuk-do. This new species is similar to Miscanthus sacchariflorus (Maxim.) Hack., and M. longiberbis (Hack.) Nakai. The characters which distinguish the above two species are short leaves and racemes, callus hairs 1-1.5-times longer than spikelet, and well-developed awns of spikelet. The specific epithet, "wangpicheonensis", is based on the name of the locality where the new species is found. We assume this new species originated from the hybridization of Miscanthus sacchariflorus (Maxim.) Hack., and M. longiberbis (Hack.) Nakai. Miscanthus wangpicheonensis is found in only one locality in Uljin-gun, Gyeongsangbuk-do, Republic of Korea.

  • The genes encoding non-specific lipid transfer proteins (nsLTPs), members of a small multigene family, show a complex pattern of expressional regulation, suggesting that some diversification may have resulted from changes in their expression after duplication. In this study, the evolution of nsLTP genes within the Poaceae family was characterized via a survey of the pseudogenes and unigenes encoding the nsLTP in rice pseudomolecules and the NCBI unigene database. nsLTP-rich regions were detected in the distal portions of rice chromosomes 11 and 12; these may have resulted from the most recent large segmental duplication in the rice genome. Two independent tandem duplications were shown to occur within the nsLTP-rich regions of rice. The genomic distribution of the nsLTP genes in the rice genome differs from that in wheat. This may be attributed to gene migration, chromosomal rearrangement, and/or differential gene loss. The genomic distribution pattern of nsLTP genes in the Poaceae family points to the existence of some differences among cereal nsLTP genes, all of which diverged from an ancient gene. The unigenes encoding nsLTPs in each cereal species are clustered into five groups. The somewhat different distribution of nsLTP-encoding EST clones between the groups across cereal species imply that independent duplication(s) followed by subfunctionalization (and/or neofunctionalization) of the nsLTP gene family in each species occurred during speciation.

  • This text was experimented and investigated the optimum production time and germination characteristics of seed that collect in Korean Chungnam, in order to offer the basic informations for slope restoration and revegetation using Poaceae plant. Optimum time of seed production was mid-late October of Miscanthus sinensis, Pennisetum alopecuroides, early November to late October of Themeda triandra var. japonica and M. sacchariflorus, and mid November of Phragmites communis. Epiphytic amount of seed full ripe was the most times in mid October of M. sinensis, P. alopecuroides and M. sacchariflorus, early November of T. triandra var. japonica, and mid November of P. communis. Seed rate of maturity was the highest times in early November of M. sinensis, P. alopecuroides and M. sacchariflorus, and mid November of T. triandra var. japonica and P. communis. Germination rate by seed collection time was the highest times in early October of M. sacchariflorus, mid October of T. triandra var. japonica, early November of M. sinensis and mid November of P. communis. Germination days by seed production time was the shortest times in early November of M. sinensis and M. sacchariflorus, mid November of T. triandra var. japonica and P. communis. Optimum temperature of germination was $20{\sim}25^{\circ}C$ in M. sinensis and P. alopecuroides, $25^{\circ}C$ in T. triandra var. japonica, and $25{\sim}30^{\circ}C$ in P. communis.

  • An unrecorded alien species plant, Phalaris paradoxa L. (Poaceae) was found in Andeok-myeon, Seogwipo-si, Jeju island, Korea. It is native to the Mediterranean region of Europe, and it is currently found worldwide. Phalaris paradoxa is distinguishable from related taxa (P. arundinacea, P. canariensis, P. minor and P. arundinacea var. picta) in Korea by the following combination of characterstics: spikelets in clusters (the upper central fertile spikelet surrounded by six lower sterile spikelets), wing of the keel. This taxon was named 'Nal-gae-ca-na-ri-sae-pul' in Korean based on its character. We provide its description, illustrations, photographs and a key of related taxa in Korea.
