The preimaginal stages of Pnigalio gyamiensis Myartseva & Kurashev, 1990 (Hymenoptera, Eulophidae), a parasitoid associated with Chrysoesthia sexguttella (Thunberg) (Lepidoptera, Gelechiidae)

open access: yesZooKeys, 2012
The larval instars of Pnigalio gyamiensis Myartseva and Kurashev are described in detail for the first time. This species is a larval-pupal ectoparasitoid of Chrysoesthia sexguttella (Thunberg) (Lepidoptera, Gelechiidae), which forms leaf mines in the ...

The structural diversity of CACTA transposons in genomes of Chenopodium (Amaranthaceae, Caryophyllales) species: specific traits and comparison with the similar elements of angiosperms

open access: yesMobile DNA, 2022
Background CACTA transposable elements (TEs) comprise one of the most abundant superfamilies of Class 2 (cut-and-paste) transposons. Over recent decades, CACTA elements were widely identified in species from the plant, fungi, and animal kingdoms, but ...

Adaptations of succulent plants for survival in desert ecosystems [PDF]

open access: yes, 2019
Cilj ovog seminara bio je nabrojati prilagodbe sukulentnih biljaka koje su im nužne za preživljavanje u pustinjskim ekosustavima. Sukulenti su biljke koje imaju posebne morfološke i ekofiziološke prilagodbe za pojačano primanje i pohranu vode.

Nuclear DNA of plastid origin (NUPTs), neglected driver of genome variation and evolutionary innovation

open access: yesThe Plant Journal, Volume 125, Issue 3, February 2026.
Significance Statement Contrary to expectation, NUPTs do not necessarily have a deleterious or ultimately neutral impact, nor are they necessarily purged from the genome. Instead, they can proliferate and eventually become fixed, generating new and novel genes, gene regions and regulatory elements, thereby significantly contributing to plant nuclear ...

Massive Mitochondrial Gene Transfer in a Parasitic Flowering Plant Clade [PDF]

open access: yes, 2013
Recent studies have suggested that plant genomes have undergone potentially rampant horizontal gene transfer (HGT), especially in the mitochondrial genome.

Floral shape and color impact heat accumulation and thermal stability of the floral microenvironment in a subalpine meadow

open access: yesAmerican Journal of Botany, Volume 113, Issue 1, January 2026.
Abstract Premise The floral thermal microenvironment impacts plant reproduction through its effects on gametophyte performance and plant–pollinator interactions. Color and shape are axes of floral variation that may mediate floral temperature because they affect the absorption and reflection of solar radiation, but their interactive effects are unclear.

The genome sequence of common knotgrass, Polygonum aviculare L. (Polygonaceae) [version 1; peer review: 2 approved]

open access: yesWellcome Open Research
We present a genome assembly from an individual Polygonum aviculare (common knotgrass; Eudicot; Magnoliopsida; Caryophyllales; Polygonaceae). The genome sequence is 351.6 megabases in span.

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.

Pollinator, herbivore, and climatic selective pressures differ across a floral color transition zone

open access: yesAmerican Journal of Botany, Volume 113, Issue 1, January 2026.
Abstract Premise Spatial and temporal variations in climate and ecological interactions may underlie the origin and maintenance of floral color polymorphisms across a species range. Betalains are nitrogen‐containing, phylogenetically restricted pigments that, like the widespread and well‐studied anthocyanins and carotenoids, may attract pollinators ...
