　概要を見る

A new species of Hamamelidaceae, Eustigma honbaense H. Toyama, Tagane & V.S. Dang, sp. nov., is described from Hon Ba Nature Reserve, Vietnam. This species is similar to Eustigma oblongifolium Gardner & Champ., but differs from it in having entire leaves, longer infructescences, capsules with a longer apical part and seeds with a larger hilum. A description, preliminary conservation assessment, illustration and photographs of the new species are provided, as well as an updated key to the genus Eustigma.

　概要を見る

Two species of Meliaceae, Toona calcicola and Reinwardtiodendron humile are newly added for fl ora of Thailand. Toona calcicola, a new species from Suan Hin Pha Ngam Forest Park, Loei Province, is described and illustrated. This species is endemic to ridge of limestone hill and characterized by Cycas petraea A.Lindstr. &amp; K.D.Hill and Dracaena cambodiana Pierre ex Gagnep. Since this is the fi rst account of the genus Reinwardtiodendron to the fl ora of Thailand, the key to the genera of Meliaceae (based on fl owers) in Thailand is revised.

　概要を見る

Twenty four species of Lasianthus are documented from Bokor National Park, Kampot Province, Cambodia. Four new species, Lasianthus bokorensis, L. giganteus, L. oblanceolatus, and L. stephanocalycinus, are described based on newly collected materials. Nine species, L. austrosinensis, L. biflorus, L. chevalieri, L. clementis, L. curtisii, L. hispidulus, L. latifolius, L. sarmentosus, and L. viridiramulis, are newly recorded from Cambodia. Lasianthus viridiramulis is proposed as a replacement name for Lasianthus brevipes Craib non Valeton.

Breeding System and Seed Production in Pin‐monomorphic Populations of a Distylous Perennial, Ophiorrhiza japonica (Rubiceae) on Iriomote Island, Japan

NAKAGAWA Masato, NAIKI Akiyo

Acta Phytotaxonomica et Geobotanica ( 日本植物分類学会 )  65 ( 1 ) 43 - 48   2014年02月 [ 査読有り ]

掲載種別: 研究論文（学術雑誌）

　概要を見る

The breeding system and seed production of a distylous perennial, Ophiorrhiza japonica, were analyzed on Iriomote Island, located near the southwestern end of the Ryukyu Islands. On Iriomote, O. japonica is monomorphic with a pin morph. Artificial pollination experiments confirmed self- and intramorph compatibility in the populations, but automatic self-pollination was not detected. Seed set in 12 sampling plots in two natural populations was constant and abundant, indicating high pollinator availability. Our results indicate that self compatibility can be assumed to have been important in the establishment of the monomorphic populations on Iriomote Island. The loss of distyly is not characterized by specialization in self-fertilization, but rather intramorph compatibility can be assumed to have been more important in maintenance of the pin-monomorphic population as a factor facilitating outbreeding

Development of microsatellite markers for Croomia japonica and cross-amplification in its congener

　概要を見る

Croomia is a small monocotyledonous genus with eastern Asian eastern North American floristic disjunction. The Croomia species are endangered and in urgent need of conservation. In this study, we report the development and characterization of 11 polymorphic compound microsatellite markers from Croomia japonica. Moreover, transferability and polymorphism of these primers was tested across Croomia heterosepala and Croomia pauciflora. All of them were transferable and polymorphic in these species. The number of alleles per locus ranged from 2 to 14 (mean: 7.7), 2 to 20 (mean: 7.3) and 2 to 16 (mean: 8.2), while the observed (and expected) heterozygosities ranged from 0.053 to 1.000 (0.053-0.918), 0.000 to 1.000 (0.656-0.945) and 0.190 to 0.905 (0.251-0.937) in populations of C japonica, C heterosepala and C pauciflora, respectively. Most loci in the Croomia populations deviated significantly from the HWE expectations. Significant heterozygosity deficiency was found but no bottleneck was detected in Croomia. These polymorphic markers will be useful tool to study the genetic diversity and the population genetic structure, evolution of Croomia species and for establishment of effective conservation strategies.

Heterostyly and the possibility of its breakdown by polyploidization

Akiyo Naiki

PLANT SPECIES BIOLOGY ( WILEY-BLACKWELL )  27 ( 1 ) 3 - 29   2012年01月 [ 査読有り ]

掲載種別: 研究論文（学術雑誌）

　概要を見る

Heterostyly is a genetically controlled sexual polymorphism promoting outcrossing by animal pollinators. The occurrence of heterostyly in angiosperms was investigated, and 199 genera in 28 families in 15 orders were recognized as taxa that contain heterostylous species. A correlation between the occurrence of heterostyly and ploidy level was found in some limited groups in Primulaceae and Rubiaceae. In such taxa, individuals with a lower ploidy level tended to have heterostyly and individuals with a higher ploidy level tended to have monomorphic flowers. It appears reasonable that the first step of the breakdown of heterostyly was the recombination of the supergene in a diploid heterostylous plant, and then poyploidization incidentally occurred. Polyploidization itself does not necessarily appear to have direct effects on the breakdown of heterostyly.
