Effects of abiotic components induced by biochar on microbial communities
Acta Agriculturae Scandinavica, Section B - Soil & Plant Science, 2013 Soil microorganisms play an important role on ecosystems and are influenced by a variety of abiotic and biotic variables. The influence of biochar on the microbial community has been reported, but its mechanism modifying soil microbial distribution is less understood.

Abiotic molecular oxygen production -- ionic pathway from sulphur dioxide [PDF]
arXiv, 2021 Molecular oxygen, O$_2$, is vital to life on Earth and possibly on other planets. Although the biogenic processes leading to its accumulation in Earth's atmosphere are well understood, its abiotic origin is still not fully established. Here, we report combined experimental and theoretical evidence for electronic-state-selective production of O$_2$ from

Robust monomer-distribution biosignatures in evolving digital biota [PDF]
Astrobiology 11 (2011) 959-968, 2011 Because organisms synthesize component molecules at rates that reflect those molecules' adaptive utility, we expect a population of biota to leave a distinctive chemical signature on their environment that is anomalous given the local (abiotic) chemistry.

Pollen limitation of native plant reproduction in an urban landscape
American Journal of Botany, Volume 109, Issue 12, Page 1969-1980, December 2022., 2022 Abstract Premise Evidence suggests that bees may benefit from moderate levels of human development. However, the effects of human development on pollination and reproduction of bee‐pollinated plants are less‐well understood. Studies have measured natural variation in pollination and plant reproduction as a function of urbanization, but few have ...

American Journal of Botany, Volume 109, Issue 12, Page 1991-2005, December 2022., 2022 Abstract Premise Numerous processes influence plant distributions and co‐occurrence patterns, including ecological sorting, limiting similarity, and stochastic effects. To discriminate among these processes and determine the spatial scales at which they operate, we investigated how functional traits and phylogenetic relatedness influence the ...

Plant cell wall integrity maintenance as an essential component of biotic stress response mechanisms
Frontiers in Plant Science, 2012 Plant cell walls provide structural support during development and represent the first line of defense against biotic and abiotic stress. In recent years evidence has accumulated that a dedicated plant cell wall integrity maintenance mechanism exists ...

Biological Research, 2022 Background Cytokinin signal transduction is mediated by a two-component system (TCS). Two-component systems are utilized in plant responses to hormones as well as to biotic and abiotic environmental stimuli. In plants, response regulatory genes (RRs) are
