Blüten, Bestäuber und ihre Bakterien – eine Dreiecksbeziehung

Weinhold A*, Keller A *corresponding author

Biospektrum 2025

The plant-microbe-pollinator triangle represents a mutualistic tripartite interaction network among plants, microbes, and insects.

Bumble bee microbiota shows temporal succession and increase of lactic acid bacteria when exposed to outdoor environments

Weinhold A*, Grüner E, Keller A *corresponding author

Frontiers in Cellular and Infection Microbiology 2024

The bumble bee microbiota showed a dynamic temporal succession with distinct compositional changes and diversification over time when placed outdoor.

Bowel movement: Integrating host mobility and microbial transmission across host taxa

Weinhold A* *corresponding author

Frontiers in Microbiology 2022

Animal movement has been little regarded in host microbiota frameworks, though it can directly influence major drivers of the host microbiota. Host movement can also extend the boundaries of microbial dispersal limitations and connect habitat patches across plant-pollinator networks.

Plant responses to insect eggs are not induced by egg-associated microbes, but by a secretion attached to the eggs

Paniagua Voirol LR, Valsamakis G, Lortzing V, Weinhold A, Johnston PR, Fatouros NE, Kunze R, Hilker M

Plant Cell Environ 2020

We conclude that glandular secretions rather than egg-associated microbes act in a dose-dependent manner as elicitor of the egg-mediated enhancement of the plant's defence against insect larvae.

Transgenerational stress-adaption: an opportunity for ecological epigenetics

Weinhold A* *corresponding author

Plant Cell Rep. 2018

In the recent years, there has been considerable interest to investigate the adaptive transgenerational plasticity of plants and how a “stress memory” can be transmitted to the following generation. Although, increasing evidence suggests that transgenerational adaptive responses have widespread ecological relevance, the underlying epigenetic processes have rarely been elucidated.

Specificity of root microbiomes in native-grown Nicotiana attenuata and plant responses to UVB increase Deinococcus colonization

Santhanam R, Oh Y, Kumar R, Weinhold A, Luu VT, Groten K, Baldwin IT

Molecular Ecology 2017

We analysed several factors potentially affecting root microbiome structure – the importance of geographic location of natural populations, the microbiome of native seeds as putative source of colonization and the effect of a plant's response to UVB exposure on root colonization of highly abundant species.

Label-free nanoUPLC-MS^E based quantification of antimicrobial peptides from the leaf apoplast of Nicotiana attenuata

Weinhold A*, Wielsch N, Svatoš A, Baldwin IT *corresponding author

BMC Plant Biology 2015

The method allows for the rapid quantification of apoplastic peptides without time-consuming purification or chromatographic steps and can be easily adapted to other plant species.

Isolating fungal pathogens from a dynamic disease outbreak in a native plant population to establish plant-pathogen bioassays for the ecological model plant Nicotiana attenuata

Schuck S, Weinhold A, Luu VT, Baldwin IT

PLoS ONE 2014

We describe a fungal disease outbreak in a native N. attenuata population comprising 873 plants. Native fungal pathogens were isolated from diseased plants, characterized genetically, chemotaxonomically and morphologically, revealing several isolates of the ascomycete genera Fusarium and Alternaria.

Progressive 35S promoter methylation increases rapidly during vegetative development in transgenic Nicotiana attenuata plants

Weinhold A*, Kallenbach M, Baldwin IT *corresponding author

BMC Plant Biology 2013

Genetically modified plants are widely used in agriculture and increasingly in ecological research to enable the selective manipulation of plant traits in the field. Despite their broad usage, many aspects of unwanted transgene silencing throughout plant development are still poorly understood.

Efficient screening of transgenic plant lines for ecological research

Gase K, Weinhold A, Bozorov TA, Schuck S, Baldwin IT

Molecular Ecology Resources 2011

Plants stably transformed to manipulate the expression of genes mediating ecological performance have profoundly altered research in plant ecology. We developed a flow chart that optimizes the screening process to efficiently select transformed plants for ecological research.
