Abstract Available plastomes of the Lauraceae show similar structure and varied size, but there has been no systematic comparison across the family. In order to understand the variation in plastome size and structure in the Lauraceae and related families of magnoliids, we here compare 47 plastomes, 15 newly sequenced, from 27 representative genera. We reveal that the two shortest plastomes are in the parasitic Lauraceae genus Cassytha, with lengths of 114,623 (C. filiformis) and 114,963 bp (C. capillaris), and that they have lost NADH dehydrogenase (ndh) genes in the large single-copy region and one entire copy of the inverted repeat (IR) region. The plastomes of the core Lauraceae group, with lengths from 150,749 bp (Nectandra angustifolia) to 152,739 bp (Actinodaphne trichocarpa), have lost trnI-CAU, rpl23, rpl2,afragmentofycf2, and their intergenic regions in IRb region, whereas the plastomes of the basal Lauraceae group, with lengths from 157,577 bp (Eusideroxylon zwageri) to 158,530 bp (Beilschmiedia tungfangen- sis), have lost rpl2 in IRa region. -
Estructura, Ontogenia Y Vascularización De Las Flores E Inflorescencias De Drimys Granadensis (Winteraceae)
Estructura, ontogenia y vascularización de las flores e inflorescencias de Drimys granadensis (Winteraceae) Xavier Marquínez Departamento de Biología, Facultad de Ciencias, Universidad Nacional de Colombia. Bogotá, Colombia; [email protected] Recibido 12-VIII-2013. Corregido 10-XII-2013. Aceptado 28-I-2014. Abstract: Structure, ontogeny and vascularization of the flowers and inflorescences of Drimys granadensis (Winteraceae). Drimys granadensis is a widespread species in montane forests of South and Central America. In this research, the structure, ontogeny, phyllotaxis and vascularization of the flowers and inflorescences of this species was studied in a population from the Eastern hills of Sabana de Bogota, Colombia. The methods used applied both optical microscopy, with astra blue-fuchsin staining, and scanning electron microscopy, using critical point dryed and gold-paladium metallized samples. Besides, results were compared with those of Drimys winteri, a widely studied species distributed in Chile and Argentina. Additionally, we studied the detail of the floral anatomy to determine the bracteal or calicine identity of the caliptra. I confirmed the proliferative status of the monothelic inflorescence, discarding alternative explanations of the terminal flower identity. I found that uniflorescences have an acropetal development until the terminal meristem becomes the terminal flower, then this flower develops rapidly resulting in a determined uniflorescence. I found pseudosyphonosthelic vasculariza- tion in peduncles and pedicels. Besides, I discovered some evidence in the vascular and anatomical structures, to consider the caliptra as the fusion product of various structures and therefore of calicine origin. The caliptra showed a whorled phyllotaxis, but the petals, stamens and carpels presented a spiral condition; phyllotaxis change was explained by the long time lapse between the initiation of the calyx and the corolla. -

Water Lilies As Emerging Models for Darwin's Abominable Mystery
OPEN Citation: Horticulture Research (2017) 4, 17051; doi:10.1038/hortres.2017.51 www.nature.com/hortres REVIEW ARTICLE Water lilies as emerging models for Darwin’s abominable mystery Fei Chen1, Xing Liu1, Cuiwei Yu2, Yuchu Chen2, Haibao Tang1 and Liangsheng Zhang1 Water lilies are not only highly favored aquatic ornamental plants with cultural and economic importance but they also occupy a critical evolutionary space that is crucial for understanding the origin and early evolutionary trajectory of flowering plants. The birth and rapid radiation of flowering plants has interested many scientists and was considered ‘an abominable mystery’ by Charles Darwin. In searching for the angiosperm evolutionary origin and its underlying mechanisms, the genome of Amborella has shed some light on the molecular features of one of the basal angiosperm lineages; however, little is known regarding the genetics and genomics of another basal angiosperm lineage, namely, the water lily. In this study, we reviewed current molecular research and note that water lily research has entered the genomic era. We propose that the genome of the water lily is critical for studying the contentious relationship of basal angiosperms and Darwin’s ‘abominable mystery’. Four pantropical water lilies, especially the recently sequenced Nymphaea colorata, have characteristics such as small size, rapid growth rate and numerous seeds and can act as the best model for understanding the origin of angiosperms. The water lily genome is also valuable for revealing the genetics of ornamental traits and will largely accelerate the molecular breeding of water lilies.

A new combination, Trithuria brevistyla (K.A.Ford) de Lange & Mosyakin, is proposed for the recently described New Zealand, South Island endemic taxon originally published as T. inconspicua subsp. brevistyla K.A.Ford. Species rank for that taxon is advocated on the basis of morphological and reproductive distinctions between that species and the closely related North Island, New Zealand endemic T. inconspicua Cheeseman sensu stricto. Some general considerations on optional species versus subspecies ranks for plant taxa in need of conservation are provided.

Why the Monophyly of Nymphaeaceae Currently Remains Indeterminate: an Assessment Based on Gene-Wise Plastid Phylogenomics
Preprints (www.preprints.org) | NOT PEER-REVIEWED | Posted: 3 May 2019 doi:10.20944/preprints201905.0002.v1 Article Why the monophyly of Nymphaeaceae currently remains indeterminate: An assessment based on gene-wise plastid phylogenomics Michael Gruenstaeudl 1,* 1 Institut für Biologie, Freie Universität Berlin, 14195 Berlin, Germany; [email protected] * Correspondence: [email protected] Received: date; Accepted: date; Published: date Abstract: The monophyly of Nymphaeaceae (water lilies) represents a critical question in understanding the evolutionary history of early-diverging angiosperms. A recent plastid phylogenomic investigation claimed new evidence for the monophyly of Nymphaeaceae, but its results could not be verified from the available data. Moreover, preliminary gene-wise analyses of the same dataset provided partial support for the paraphyly of the family. The present investigation aims to re-assess the previous conclusion of the monophyly of Nymphaeaceae under the same dataset and to determine the congruence of the phylogenetic signal across different plastome genes and data partition strategies. To that end, phylogenetic tree inference is conducted on each of 78 protein-coding plastome genes, both individually and upon concatenation, and under four data partitioning schemes. Moreover, the possible effects of various sequence variability and homoplasy metrics on the inference of specific phylogenetic relationships are tested using multiple logistic regression. Differences in the variability of polymorphic sites across codon positions are assessed using parametric and non-parametric analysis of variance. The results of the phylogenetic reconstructions indicate considerable incongruence among the different gene trees as well as the data partitioning schemes. The results of the multiple logistic regression tests indicate that the fraction of polymorphic sites of codon position 3 has a significant effect on the recovery of the monophyly of Nymphaeaceae.
