Mycorrhizal Symbiosis in Plant Growth and Stress Adaptation: From Genes to Ecosystems

Annual Review of Plant Biology, Год журнала: 2023, Номер 74(1), С. 569 - 607

Опубликована: Март 1, 2023

Plant roots associate with diverse microbes (including bacteria, fungi, archaea, protists, and viruses) collectively called the root-associated microbiome. Among them, mycorrhizal fungi colonize host improve their access to nutrients, usually phosphorus nitrogen. In exchange, plants deliver photosynthetic carbon colonizing fungi. This nutrient exchange affects key soil processes, cycle, plant health therefore has a strong influence on microbe ecosystems. The framework of regulation between arbuscular recently been established. local systemic symbiosis by status autoregulation mycorrhizae are strategies which maintain stabilizing free-market symbiosis. A better understanding synergistic effects mycorrhizosphere microorganisms is an essential precondition for use as biofertilizers bioprotectors sustainable agriculture forestry management.

The mycorrhizal symbiosis: research frontiers in genomics, ecology, and agricultural application

New Phytologist, Год журнала: 2024, Номер 242(4), С. 1486 - 1506

Опубликована: Янв. 31, 2024

Summary Mycorrhizal symbioses between plants and fungi are vital for the soil structure, nutrient cycling, plant diversity, ecosystem sustainability. More than 250 000 species associated with mycorrhizal fungi. Recent advances in genomics related approaches have revolutionized our understanding of biology ecology associations. The genomes 250+ been released hundreds genes that play pivotal roles regulating symbiosis development metabolism characterized. rDNA metabarcoding metatranscriptomics provide novel insights into ecological cues driving communities functions expressed by these associations, linking to traits such as acquisition organic matter decomposition. Here, we review genomic studies revealed involved uptake development, discuss adaptations fundamental evolution lifestyles. We also evaluated services provided networks how hold promise sustainable agriculture forestry enhancing stress tolerance. Overall, unraveling intricate dynamics is paramount promoting sustainability addressing current pressing environmental concerns. This ends major frontiers further research.

Comprehensive phylogenetic analyses of Orchidaceae using nuclear genes and evolutionary insights into epiphytism

Journal of Integrative Plant Biology, Год журнала: 2023, Номер 65(5), С. 1204 - 1225

Опубликована: Фев. 4, 2023

Orchidaceae (with >28,000 orchid species) are one of the two largest plant families, with economically and ecologically important species, occupy global diverse niches primary distribution in rainforests. Among orchids, 70% grow on other plants as epiphytes; epiphytes contribute up to ~50% diversity rainforests provide food shelter for animals microbes, thereby contributing health these ecosystems. Orchids account over two-thirds vascular an excellent model studying evolution epiphytism. Extensive phylogenetic studies subgroups have ;been crucial understanding relationships among many lineages, although some uncertainties remain. For example, subfamily Epidendroideae nearly all epiphytic tribes subtribes still controversial, hampering evolutionary analyses Here we obtained 1,450 low-copy nuclear genes from 610 including 431 newly generated transcriptomes, used them reconstruction robust trees highly supported placements subtribes. We also generally well-supported 131 genera 437 species that were not sampled by previous plastid phylogenomic studies. Molecular clock estimated origin at ~132 million years ago (Ma) divergences most 52 29 Ma. Character supports least 14 parallel origins epiphytism; such was placed recent common ancestor ~95% orchids linked modern Ten occurrences rapid increase diversification rate detected within near after K-Pg boundary, ~80% diversity. This study provides a family-wide tree thus far new insights into epiphytism plants.

Orchidaceae is one of the largest, most diverse families in angiosperms with significant ecological and economical values. Orchids have long fascinated scientists by their complex life histories, exquisite floral morphology pollination syndromes that exhibit exclusive specializations, more than any other plants on Earth. These intrinsic factors together human influences also make it a keystone group biodiversity conservation. The advent sequencing technologies transgenic techniques represents quantum leap orchid research, enabling molecular approaches to be employed resolve historically interesting puzzles basic applied biology. To date, 16 different genomes covering four subfamilies (Apostasioideae, Vanilloideae, Epidendroideae, Orchidoideae) been released. genome projects given rise massive data greatly empowers studies pertaining key innovations evolutionary mechanisms for breadth species. extensive exploration transcriptomics, comparative genomics, recent advances gene engineering linked important traits orchids multiplicity regulating networks, providing great potential genetic enhancement improvement. In this review, we summarize progress achievement fundamental research industrialized application particular focus tools, future prospects breeding post-genomic comprehensive assemblage state art knowledge industrialization.

Genome evolution in plants and the origins of innovation

New Phytologist, Год журнала: 2023, Номер 240(6), С. 2204 - 2209

Опубликована: Сен. 2, 2023

Summary Plant evolution has been characterised by a series of major novelties in their vegetative and reproductive traits that have led to greater complexity. Underpinning this diversification the genome. When viewed at scale plant kingdom, genome punctuated conspicuous instances gene whole‐genome duplication, horizontal transfer extensive loss. The periods dynamic often coincide with key traits, demonstrating coevolution genomes phenotypes macroevolutionary scale. Conventionally, complexity diversity considered through lens duplication role loss remains comparatively unexplored. However, light reductive across multiple lineages, association between phenotypic warrants attention.

Apostasia Mitochondrial Genome Analysis and Monocot Mitochondria Phylogenomics

International Journal of Molecular Sciences, Год журнала: 2023, Номер 24(9), С. 7837 - 7837

Опубликована: Апрель 25, 2023

Apostasia shenzhenica belongs to the subfamily Apostasioideae and is a primitive group located at base of Orchidaceae phylogenetic tree. However, A. mitochondrial genome (mitogenome) still unexplored, relationships between monocots mitogenomes remain unexplored. In this study, we discussed genetic diversity within its monocotyledon mitogenome. We sequenced assembled complete mitogenome shenzhenica, resulting in circular draft 672,872 bp, with an average read coverage 122× GC content 44.4%. contained 36 protein-coding genes, 16 tRNAs, two rRNAs, copies nad4L. Repeat sequence analysis revealed large number medium small repeats, accounting for 1.28% sequence. Selection pressure indicated high conservation related species. RNA editing identified 416 sites region. Furthermore, found 44 chloroplast genomic DNA fragments that were transferred from five plastid-derived genes remaining intact Finally, 28 other showed evolution classification most well determined. These findings enrich resources orchids provide valuable information on taxonomic molecular monocots.
