Recent advances in synthetic biology and materials science have given rise to a new form of materials, namely engineered living (ELMs), which are composed matter or cell communities embedded self-regenerating matrices their own artificial scaffolds. Like natural such as bone, wood, skin, ELMs, possess the functional capabilities organisms, can grow, self-organize, self-repair when needed. They also spontaneously perform programmed biological functions upon sensing external cues. Currently, ELMs show promise for green energy production, bioremediation, disease treatment, fabricating advanced smart materials. This review first introduces dynamic features systems potential developing novel We then summarize recent research progress on emerging design strategies from both perspectives. Finally, we discuss positive impacts promoting sustainability key future directions.

Fungi comprise approximately 20% of all eukaryotic species and are connected to virtually life forms on Earth. Yet, their diversity remains contentious, distribution elusive, conservation neglected. We aim flip this situation by synthesizing current knowledge. present a revised estimate 2–3 million fungal with “best estimate” at 2.5 million. To name the unknown >90% these end century, we propose recognition known only from DNA data call for large-scale sampling campaigns. an updated global map richness, highlighting tropical temperate ecoregions high diversity. further Red List assessments enhanced management guidelines aid conservation. Given that fungi play inseparable role in our lives ecosystems, considering fascinating questions remaining be answered, argue constitute next frontier biodiversity research.

Exposing their vegetative bodies to the light, lichens are outstanding amongst other fungal symbioses. Not requiring a pre-established host, 'lichenized fungi' build an entirely new structure together with microbial photosynthetic partners that neither can form alone. The signals involved in transition of fungus and compatible partner from free-living symbiotic state culminating thallus formation, termed 'lichenization', maintenance symbiosis, poorly understood. Here, we synthesise puzzle pieces scarce knowledge available into updated concept signalling lichenization, comprising five main stages: (1) 'pre-contact stage', (2) 'contact (3) 'envelopment' algal cells by fungus, (4) 'incorporation' pre-thallus (5) 'differentiation' complex thallus. Considering involvement extracellularly released metabolites each phase, propose compounds such as lectins cyclic peptides elicit early contact between symbionts-to-be, whereas phytohormone signalling, antioxidant protection carbon exchange through sugars sugar alcohols continued importance throughout all stages. In fully formed lichen thallus, secondary mineral nutrition suggested stabilize functionalities including associated microbiota.

Abstract Green algae display a wide range of extracellular matrix (ECM) components that include various types cell walls (CW), scales, crystalline glycoprotein coverings, hydrophobic compounds, and complex gels or mucilage. Recently, new information derived from genomic/transcriptomic screening, advanced biochemical analyses, immunocytochemical studies, ecophysiology has significantly enhanced refined our understanding the green algal ECM. In later diverging charophyte group algae, CW other ECM provide insight into evolution plants ways modulates during environmental stress. Chlorophytes produce diverse components, many which have been exploited for uses in medicine, food, biofuel production. This review highlights major advances studies algae.

Abstract Lichens are one of the most iconic and ubiquitous symbioses known, widely valued as indicators environmental quality and, more recently, climate change. Our understanding lichen responses to has greatly expanded in recent decades, but some biases constraints have shaped our present knowledge. In this review we focus on ecophysiology a key predicting future climates, highlighting advances remaining challenges. Lichen is best understood through complementary whole‐thallus within‐thallus scales. Water content form (vapor or liquid) central perspectives, making vapor pressure differential (VPD) particularly informative driver. Responses water further modulated by photobiont physiology phenotype, providing clear links functional trait framework. However, thallus‐level perspective incomplete without also considering dynamics, such changing proportions even identities symbionts response climate, nutrients, other stressors. These changes provide pathways for acclimation, their currently limited large gaps carbon allocation symbiont turnover lichens. Lastly, study mainly prioritized larger lichens at high latitudes, producing valuable insights underrepresenting range lichenized lineages ecologies. Key areas work include improving geographic phylogenetic coverage, greater emphasis VPD climatic factor, turnover, incorporation physiological theory traits predictive models.

Lichens are composite, symbiotic associations of fungi, algae, and bacteria that result in large, anatomically complex organisms adapted to many the world's most challenging environments. How such intricate, self-replicating lichen architectures develop from simple microbial components remains unknown because their recalcitrance experimental manipulation. Here, we report a metagenomic metatranscriptomic analysis Xanthoria parietina at different developmental stages. We identified 168 genomes symbionts lichen-associated microbes across sampled thalli, including representatives green three classes 14 bacterial phyla. By analyzing occurrence individual species thalli diverse environments, defined both substrate-specific core lichen. Metatranscriptomic principal fungal symbiont stages lichen, compared with axenically grown fungus, revealed differential gene expression profiles indicative lichen-specific transporter functions, specific cell signaling, transcriptional regulation, secondary metabolic capacity. Putative immunity-related proteins structurally conserved secreted resembling pathogen effectors were also identified, consistent role for immunity modulation morphogenesis.

Fungi engage in diverse symbiotic relationships with phototrophs. Lichens, complexes involving fungi and either cyanobacteria, green algae, or both, have forming the external layer much of interior. We found an erect thallus resembling a lichen yet unexpected structure composed interwoven cyanobacterial filaments numerous fungal hyphae inserted within individual sheaths, contrasting typical structure. Phylogenetics identified fungus as previously undescribed species, Serendipita cyanobacteriicola , closely related to endophytes, cyanobacterium belongs family Coleofasciculaceae, representing genus species not classified, Symbiothallus taiwanensis . These thalli exhibit nitrogen-fixing activity similar mosses but lower than cyanolichens. Both partners are distinct from known lichen-forming symbionts, uncovering phylogenetically morphologically unprecedented thallus-forming fungus-cyanobacterium symbiosis. propose name “phyllosymbia” for these underscore their unique nature leaf-like appearance. This finding marks unknown instance solely residing structures generated by cyanobacteria.
