The multilevel organismal diversity approach deciphers difficult to distinguish nudibranch species complex

Scientific Reports, 2021
Species identification is a key procedure for broad-scoped ecological, phylogeographic and evolutionary studies. However, to perform a taxonomic study in the molecular era is a complicated task that has many pitfalls.

Functional Mapping of Neurodevelopmental Disease Pathways to Key Neurodevelopmental Processes Represented in the Developmental Neurotoxicity In Vitro Testing Battery

Advanced Science, EarlyView.
Human‐relevant methods are essential for modern chemical safety assessment. This study helps define the capabilities and boundaries of an in vitro testing battery for developmental neurotoxicity by exploring its biological applicability domain. By linking neurodevelopmental disease‐related pathways to key neurodevelopmental processes, the work enhances

Transcription Factor Promiscuity Drives Regulatory Rewiring and Evolvability in Gene Networks in Bacteria

Advanced Science, EarlyView.
When a master transcription factor (TF) is lost, bacteria can rapidly rewire gene regulatory networks by co‐opting related regulators. Using experimental evolution in Pseudomonas fluorescens, we show that TF promiscuity (low‐level, non‐cognate binding) provides the raw material for rewiring. Successful co‐option follows a predictable hierarchy governed

A Crystalline and Thermally Stable Selenocysteine Selenenic Acid

Angewandte Chemie, EarlyView.
The long‐sought catalytic intermediate of selenoproteins, selenocysteine selenenic acid (Sec–SeOH), is isolated for the first time at ambient temperature. A bioinspired selenopeptide sequence encapsulated within a protective molecular cradle and an oxidant‐free route from selenenyl iodide (Sec–SeI) enable the isolation of Sec–SeOH. Contrary to the long‐

MFPD: A Multiple Fungal Pathogen Detection Pipeline Across Diverse Habitats

Advanced Science, EarlyView.
The MFPD pipeline integrates a comprehensive ITS reference database of fungal pathogens, optimized parameters, and algorithms tailored for both full‐length and subregion sequences that balance accuracy and computational efficiency; it enables high‐throughput, species‐level identification from amplicon sequencing data, supporting large‐scale ...

Ghost introgression facilitates genomic divergence of a sympatric cryptic lineage in Cycas revoluta

Ecology and Evolution, 2023
A cryptic lineage is a genetically diverged but morphologically unrecognized variant of a known species. Clarifying cryptic lineage evolution is essential for quantifying species diversity. In sympatric cryptic lineage divergence compared with allopatric

Fine‐Tuned Regulation of mRNA Translation and Transport by STAU2 Condensate Facilitates Neuronal Development and Plasticity

Advanced Science, EarlyView.
STAU2 undergoes phase separation to form dynamic condensates that package target mRNAs and deliver them to the distal ends of growing neuronal dendrites. STAU2 condensates stabilize embedded mRNAs and repress their translation. Synaptic activity bidirectionally remodels STAU2 condensates, coordinating local translation of STAU2‐associated mRNAs ...

Niche partitioning in a sympatric cryptic species complex [PDF]

Ecology and Evolution, 2016
AbstractCompetition theory states that multiple species should not be able to occupy the same niche indefinitely. Morphologically, similar species are expected to be ecologically alike and exhibit little niche differentiation, which makes it difficult to explain the co‐occurrence of cryptic species.

SERRATE Regulates Floral Meristem Activity by Antagonizing SHOOT MERISTEMLESS and Repressing Cytokinin Signaling

Advanced Science, EarlyView.
Floral meristem (FM) activity is crucial for the initiation of floral organs. In this study, SE represses IPT7 expression and cytokinin signaling via both the miR171c‐5p–KNAT2 and miR164c–CUC1/2–KNAT2 regulatory modules, thereby repressing FM activity. In contrast, STM induces both KNAT2 and IPT7 expression.

Wolbachia infections mimic cryptic speciation in two parasitic butterfly species, Phengaris teleius and P. nausithous (Lepidoptera: Lycaenidae).

PLoS ONE, 2013
Deep mitochondrial divergence within species may result from cryptic speciation, from phylogeographic isolation or from endosymbiotic bacteria like Wolbachia that manipulate host reproduction. Phengaris butterflies are social parasites that spend most of
