mBio, 2019 Fungal spores germinate and undergo vegetative growth, leading to either asexual or sexual reproductive dispersal. Previous research has indicated that among developmental regulatory genes, expression is conserved across nutritional environments, whereas

(Hemiptera: Pseudococcidae): are asexual reproduction and hybridization possible?
, 2023 The study of insect reproduction is important from both basic and applied perspectives, particularly in mealybugs (Hemiptera: Pseudococcidae), because of the diversity of reproduction modes and also because they are important agricultural pests.

Pest Management Science, EarlyView.Molecular screening of 140 field‐collected Myzus persicae aphids revealed target‐site mutations L1014F, M918L, M918T, and L932F in the sodium channel and S431F in Ace2. The M918L mutation was the primary driver of high pyrethroid (cypermethrin) resistance, while S431F served as a definitive marker for carbamate (pirimicarb) resistance.

Unusually Large Number of Mutations in Asexually Reproducing Clonal Planarian Dugesia japonica. [PDF]
PLoS ONE, 2015 We established a laboratory clonal strain of freshwater planarian (Dugesia japonica) that was derived from a single individual and that continued to undergo autotomous asexual reproduction for more than 20 years, and we performed large-scale genome ...

Pest Management Science, EarlyView.SDHI resistance is reported and characterised for the first time in the oilseed rape phoma stem canker pathogen Plenodomus biglobosus (Leptosphaeria biglobosa). We investigate cross‐resistance patterns, associated SDH target‐site mutations, possible fitness costs, and consider the implications for disease and resistance management.

Retrospective image analysis for long‐term demography using Google Earth imagery
Remote Sensing in Ecology and Conservation, EarlyView.We demonstrate that high‐resolution Google Earth imagery, combined with minimal field validation, enables retrospective tracking of individual invasive plants. The image shows one of the monitored individuals of Opuntia sp. in Greece. Our approach reveals long‐term demographic patterns, recruitment dynamics, and spatial expansion without continuous ...

Expansion of genes encoding piRNA-associated argonaute proteins in the pea aphid: diversification of expression profiles in different plastic morphs. [PDF]
PLoS ONE, 2011 Piwi-interacting RNAs (piRNAs) are known to regulate transposon activity in germ cells of several animal models that propagate sexually. However, the role of piRNAs during asexual reproduction remains almost unknown.

On the asexual reproduction of Plagiochila pluma Steph. [PDF]
, 1992 Four types of asexual reproduction in Plagiochila and the Plagiochilaceae are known: propagules, caducous leaves, gemmae and cladia. Plagiochila pluma Steph. has caducous leaves and teeth with regenerants.
