Jumping plant-lice of the Paurocephalinae (Insecta, Hemiptera, Psylloidea): systematics and phylogeny [PDF]

open access: yes, 2003
Much confusion exists with respect to the content and definition of the psyUid subfamily Paurocephalinae. Based on a cladistic analysis of 22 morphological characters (16 adult and 6 larval), the subfamily is redefined to comprise the following five ...

The Comparative Study on Molecular Phylogenetics and Development of Microsatellite Primers From Durian Chloroplast Genomes

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
Based on the chloroplast genomes, the phylogenetic relationship of durian cultivars was visualized. Furthermore, 13 SSR primer pairs were designed and could be applied for genetic diversity and genotyping studies. ABSTRACT Durian, or Durio zibethinus, is an exotic fruit with high economic value in Southeast Asia.

First steps towards a floral structural characterization of the major rosid subclades [PDF]

open access: yes, 2018
A survey of our own comparative studies on several larger clades of rosids and over 1400 original publications on rosid flowers shows that floral structural features support to various degrees the supraordinal relationships in rosids proposed by ...

Phylogeny of the core Malvales: evidence from ndhF sequence data [PDF]

open access: yesAmerican Journal of Botany, 1999
The monophyly of the group comprising the core malvalean families, Bombacaceae, Malvaceae, Sterculiaceae, and Tiliaceae, was recently confirmed by molecular studies, but the internal structure of this clade is poorly understood. In this study, we examined sequences of the chloroplast ndhF gene (aligned length 2226 bp) from 70 exemplars representing 35 ...

A Group 6 LEA Protein Plays Key Roles in Tolerance to Water Deficit, and in Maintaining the Glassy State and Longevity of Seeds

open access: yesPlant, Cell &Environment, Volume 48, Issue 9, Page 6874-6896, September 2025.
ABSTRACT Plants have a wide range of adaptive and protective mechanisms to cope with dehydration. Central in these processes are the Late Embryogenesis Abundant (LEA) proteins, whose levels notably increase in response to dehydration during seed development and vegetative tissues.

The complete chloroplast genome of the lipstick tree, Bixa Orellana (Bixaceae)

open access: yesMitochondrial DNA. Part B. Resources, 2019
Bixa orellana is a small tree known for its red, oil-soluble pigment contained in the seed coat that is used as a natural dye and food coloring. In this study, we assembled and characterized the complete chloroplast genome of B.

Progress and problems in the assessment of flower morphology in higher-level systematics [PDF]

open access: yes, 2018
Floral features used for characterization of higher-level angiosperm taxa (families, orders, and above) are assessed following a comparison of earlier (precladistic/premolecular) and current classifications.

Progestogens and androgens influence root morphology of angiosperms in a brassinosteroid‐independent manner

open access: yesThe Plant Journal, Volume 123, Issue 5, September 2025.
Significance Statement Plants produce progesterone and androgens, which alter root morphology in A. thaliana and 60% of tested angiosperms. Brassinosteroids seem uninvolved. Understanding the mechanism is like navigating an unknown city—exemplarily Dittelbrunn (a small village in Bavaria)—where the expected shortcut (interaction with brassinosteroids ...

The complete chloroplast genome sequence of Chengal (Neobalanocarpus heimii, Dipterocarpaceae), a durable tropical hardwood

open access: yesMitochondrial DNA. Part B. Resources, 2019
Known for its durable timber quality, Neobalanocarpus heimii (King) Ashton is a highly sought after tree species endemic to the Malay Peninsula. Due to its scarcity and high value, the tree is classified under the IUCN Red List categories of Vulnerable ...

Phylogenetic inference in Rafflesiales: the influence of rate heterogeneity and horizontal gene transfer

open access: yesBMC Evolutionary Biology, 2004
Background The phylogenetic relationships among the holoparasites of Rafflesiales have remained enigmatic for over a century. Recent molecular phylogenetic studies using the mitochondrial matR gene placed Rafflesia, Rhizanthes and Sapria (Rafflesiaceae s.
