Resolving taxa in a challenging orchid species complex using evidence from phylogenetics, morphometrics and floral scent chemistry

TAXON, EarlyView.
Abstract Species can be difficult to circumscribe using morphology alone, and additional data can thus be useful for resolving challenging species complexes. Here we provide a case study of a South African orchid species complex which we resolved by analysing morphology, floral scent chemistry and molecular data.

A contemplation on the secondary origin of green algal and plant plastids

Acta Societatis Botanicorum Poloniae, 2014
A single origin of plastids and the monophyly of three “primary” plastid-containing groups – the Chloroplastida (or Viridiplantae; green algae+land plants), Rhodophyta, and Glaucophyta – are widely accepted, mainstream hypotheses that form the basis for ...

Phylogenomic evidence reveals non‐monophyly of Paepalanthoideae (Eriocaulaceae) and challenges the broad concept of Paepalanthus

TAXON, EarlyView.
Abstract Eriocaulaceae is a pantropical family of approximately 1200 species across 18 genera, with its highest diversity in the Neotropical region. Traditionally, the family has been divided into two subfamilies, Eriocauloideae and Paepalanthoideae, based on floral traits. Here, we use target‐capture sequencing of nuclear markers to test the monophyly

Integrative taxonomy of the Ceratozamia mexicana Brongn. (Zamiaceae) species complex from a phylogeographic perspective

Plant Species Biology, EarlyView.
Recent research has ignited a renewed interest in Ceratozamia cycads, unveiling their remarkable diversity. While previous studies primarily focused on morphology, this investigation employs a multidisciplinary approach, integrating phylogenetics, morphology, and ecological niches. Our methods identify seven distinct lineages as separate species.

Shifting microbial communities in acidified seawaters: insights from polychaetes living in the CO2 vent of Ischia, Italy

Integrative Zoology, EarlyView.
The microbiome of polychaetes Syllis prolifera and Platynereis massiliensis complex changes in naturally acidified CO2 vents. A slight degree of acidification is associated with relevant changes in the microbial community, stressing the importance of investigations about the possible effects of ocean acidification on key biological and ecological ...

Highly Reduced Plastid Genomes of the Non-photosynthetic Dictyochophyceans Pteridomonas spp. (Ochrophyta, SAR) Are Retained for tRNA-Glu-Based Organellar Heme Biosynthesis

Frontiers in Plant Science, 2020
Organisms that have lost their photosynthetic capabilities are present in a variety of eukaryotic lineages, such as plants and disparate algal groups. Most of such non-photosynthetic eukaryotes still carry plastids, as these organelles retain essential ...

A Practical Comparison of Short‐ and Long‐Read Metabarcoding Sequencing: Challenges and Solutions for Plastid Read Removal and Microbial Community Exploration of Seaweed Samples

Molecular Ecology Resources, EarlyView.
ABSTRACT Short‐read metabarcoding analysis is the gold standard for accessing partial 16S and ITS genes with high read quality. With the advent of long‐read sequencing, the amplification of full‐length target genes is possible, but with low read accuracy.

In Vitro Synthesis of Chlorophyll A in the Dark Triggers Accumulation of Chlorophyll A Apoproteins in Barley Etioplasts” [PDF]

, 1990
An in vitro translation system using lysed etioplasts was developed to test if the accumulation of plastid-encoded chlorophyll a apoproteins is dependent on the de novo synthesis of chlorophyll a.

Stromule extension along microtubules coordinated with actin-mediated anchoring guides perinuclear chloroplast movement during innate immunity. [PDF]

, 2018
Dynamic tubular extensions from chloroplasts called stromules have recently been shown to connect with nuclei and function during innate immunity. We demonstrate that stromules extend along microtubules (MTs) and MT organization directly affects stromule

Plastid intramembrane proteolysis

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2015
Progress in the field of regulated intramembrane proteolysis (RIP) in recent years has not surpassed plant biology. Nevertheless, reports on RIP in plants, and especially in chloroplasts, are still scarce. Of the four different families of intramembrane proteases, only two have been linked to chloroplasts so far, rhomboids and site-2 proteases (S2Ps ...
