Abstract

ERLINAWATI, I., ASIH, N. P. S., KURNIAWAN, A. & YUZAMMI. 2019. Studies on the Araceae of the Lesser Sunda Islands II: New record for Scindapsus hederaceus Miq. in Bali. Reinwardtia 18(2): 51?64. ? The native Araceae of the Lesser Sunda Islands consists of 19 genera and 33 species, of which Scindapsus hederaceus Miq. is newly reported for Bali. This species distributed from Indo-China to West and Central Malesia. Formerly, in Indonesia the species has been found in Sumatra, Java and Borneo. Short descriptions of all species found in the Lesser Sunda Islands and a key to the genera are provided.

Abstract

In this study, the genome of an endemic Sulawesi’s plant, Medinilla tapete-magicum was sequenced using Illumina NextSeq 500 and assembled the whole chloroplast genome. Results showed that the cpGenome is 155,602 bp in size with typical quadripartite structure of a large single copy (LSC) region (85,409 bp), a short single copy (SSC) region (16,629 bp), and a pair of inverted repeats (IRs) regions (26,782 bp). The cpGenome is composed of 132 genes, which consists of 87 protein coding genes, 37 tRNAs, and 8 rRNAs. The sliding window analyses showed that psbB-psbH and ndhF-rpl32 can potentially be used as markers. Microsatellite motifs of mononucleotide A and T dominated in the cpGenome. The phylogenetic trees from the concatenated 76 shared protein coding gene sequences showed the Medinilla clade was monophyletic and M. tapete-magicum is a sister species in the SE Asian clade which contain M. magnifica and M. speciosa.

Abstract

Alocasia is a genus of perennial, flowering plants from Araceae, native to tropical and subtropical Asia and eastern Australia. The corms of some Alocasia species are edible, but many Alocasia species are cultivated as ornamentals. Despite the rich biodiversity of Alocasia, there have been limited studies on the morphology and anatomy of these genera. Our study aimed to describe the morphology and growth patterns of two Alocasia species found in Papua, one of the remote regions in Indonesia, A. brancifolia and A. lauterbachiana. The existence of A. lauterbachiana in Papua has never been reported before. The two Alocasia species can be distinguished by their distinct leaf shapes and colors. Alocasia brancifolia has pinnatifid leaves, while A. lauterbachiana has serrated leaves. The leaf of A. brancifolia is thin and predominantly green with faint spots, while the petioles exhibit stripes of brown and green, whereas A. lauterbachiana leaves are thicker and have darker green and reddish color. Due to their attractive leaf shape and colors, both species have the potential to be developed as ornamental potted plants. In terms of growth, A. lauterbachiana exhibited faster growth than A. brancifolia. However, A. brancifolia demonstrated a 50% increase in multiplication over the 16-week study period, while A. lauterbachiana primarily grew taller and larger. This information could prove valuable for future studies to optimize the growth and cultivation techniques of the two Alocasia species for commercial purposes, particularly ornamental foliage plants.

Abstract

Alocasia longiloba Miq. is a member of the Araceae family, which was complex and has diverse leaf shapes, color, and venation. Studies on the diversity of A. longiloba focused mostly on morphological characteristics, while the genetic diversity of this species has never been published. This research aims to determine the genetic diversity and phylogeny of the Indonesian accession of A. longiloba based on molecular approaches using trnL-F IGS region. A total of 20 accesses of A. longiloba from Indonesia were sequenced then together with 11 DNA sequences of A. longiloba registered at the NCBI, were aligned with the Mesquite software. Genetic diversity was examined using DnaSP ver. 6.12.03. The phylogenetic tree was reconstructed by MEGA 11 using the Maximum Parsimony method and the Tree-Bisection-Regrafting (TBR) algorithm. Among 389 sites recorded, 356 site were invariable, 5 site were variable and 28 site were gaps or missing data. This genetic variation in the form of insertion, deletion, transition, and transversion and the deletion event has received the most contributions. Reconstruction of the phylogenetic tree resulted in A. longiloba being polyphyletic. The use of cpDNA with the trnL-F IGS region could not show the relationship between the Indonesian accession of A. longiloba, so further research is needed in other regions of chloroplast and nuclear DNA.
