Forests are not only the most predominant of Earth's terrestrial ecosystems, but also core supply for essential products human use. However, global climate change and ongoing population explosion severely threatens health forest ecosystem aggravtes deforestation degradation. Forest genomics has great potential increasing productivity adaptation to changing climate. In last two decades, field advanced quickly owing advent multiple high-throughput sequencing technologies, single cell RNA-seq, clustered regularly interspaced short palindromic repeats (CRISPR)-mediated genome editing, spatial transcriptomes, as well bioinformatics analysis which have led generation multidimensional, multilayered, spatiotemporal gene expression data. These together with basic technologies routinely used in plant biotechnology, enable us tackle many important or unique issues biology, provide a panoramic view an integrative elucidation molecular regulatory mechanisms underlying phenotypic changes variations. this review, we recapitulated advancement current status 12 research branches genomics, then provided future directions focuses each area. Evidently, shift from simple biotechnology-based research, setup investigation interpretation development differentiation just begun emerge.

Wood of trees: Cellular structure, molecular formation, and genetic engineering

Journal of Integrative Plant Biology, Год журнала: 2023, Номер 66(3), С. 443 - 467

Опубликована: Ноя. 30, 2023

Wood is an invaluable asset to human society due its renewable nature, making it suitable for both sustainable energy production and material manufacturing. Additionally, wood derived from forest trees plays a crucial role in sequestering significant portion of the carbon dioxide fixed during photosynthesis by terrestrial plants. Nevertheless, with expansion global population ongoing industrialization, coverage has been substantially decreased, resulting challenges supply. practices have changed away natural forests toward plantation forests. Thus, understanding underlying genetic mechanisms formation foundation developing high-quality, fast-growing trees. Breeding ideal using technologies attracted interest many. Tremendous studies carried out recent years on molecular, genetic, cell-biological formation, considerable progress findings achieved. These indicate enormous possibilities prospects tree improvement. This review will outline assess cellular molecular as well genetically improving trees, address future development prospects.

Vascular cambium stem cells: past, present and future

New Phytologist, Год журнала: 2024, Номер 243(3), С. 851 - 865

Опубликована: Июнь 18, 2024

Secondary xylem and phloem originate from a lateral meristem called the vascular cambium that consists of one to several layers meristematic cells. Recent lineage tracing studies have shown only cambial cells in each radial cell file functions as stem cell, capable producing both secondary phloem. Here, we first review how phytohormones signalling peptides regulate formation activity. We then propose concept, familiar apical meristems, could be applied studies. Finally, discuss this concept set basis for future research.

Computational modeling of cambium activity provides a regulatory framework for simulating radial plant growth

eLife, Год журнала: 2023, Номер 12

Опубликована: Март 10, 2023

Precise organization of growing structures is a fundamental process in developmental biology. In plants, radial growth mediated by the cambium, stem cell niche continuously producing wood (xylem) and bast (phloem) strictly bidirectional manner. While this contributes large parts to terrestrial biomass, cambium dynamics eludes direct experimental access due obstacles live-cell imaging. Here, we present cell-based computational model visualizing activity integrating function central regulators. Performing iterative comparisons plant anatomies, conclude that receptor-like kinase PXY its ligand CLE41 are part minimal framework sufficient for instructing tissue organization. By tissue-specific wall stiffness values, moreover probe influence physical constraints on geometry. Our highlights role intercellular communication within shows limited number factors create production.

Stem Cells and Differentiation in Vascular Tissues

Annual Review of Plant Biology, Год журнала: 2024, Номер 75(1), С. 399 - 425

Опубликована: Фев. 22, 2024

Plant vascular tissues are crucial for the long-distance transport of water, nutrients, and a multitude signal molecules throughout plant body and, therefore, central to growth development. The intricate development is orchestrated by unique populations dedicated stem cells integrating endogenous as well environmental cues. This review summarizes our current understanding vascular-related cell biology tissue differentiation. We present an overview molecular cellular mechanisms governing maintenance fate determination highlight interplay between intrinsic external In this context, we emphasize role transcription factors, hormonal signaling, epigenetic modifications. also discuss emerging technologies large repertoire types associated with tissues, which have potential provide unprecedented insights into specialization anatomical adaptations distinct ecological niches.

The modern plant vascular system is a central feature of extant angiosperms and consists xylem, phloem, the intervening procambium (Lucas et al., 2013).During vegetative growth, apical meristem serves as continuous source procambial initial cells, which produce primary procambium.In secondary cambium, derived from procambium, acts stem cell reservoir continues to give rise xylem phloem cells.The formation tissue well-organized developmental process, whose step regulation fates.It governed by cell-to-cell communication, symplastic movement signaling molecules contributes development.Various secreted peptides well hormones play crucial roles in communication for regulating development (Fukuda Ohashi-Ito, 2019).Among peptides, several members CLAVATA3 (CLV3)/ EMBRYO SURROUNDING REGION, or CLE, family act at different points key processes (Hazak Hardtke, 2016;Fukuda 2019).The CLE genes are conserved among land plants.In Arabidopsis (Arabidopsis thaliana) genome, there 32 encoding 27 distinct (Yamaguchi 2016).CLE precursor proteins contain an N-terminal signal peptide least one C-terminal 12-14 amino acid domain, mature produced through proteolytic cleavage.The activity some processed increased modifications such hydroxylation on Pro residues, cases glycosylation with three arabinose residues (Ito 2006;Ohyama 2009;Matsubayashi, 2011;Shinohara Matsubayashi, development, CLE41/CLE44, CLE45, CLE9/CLE10 function processes.In addition, other phytosulfokine EPIDERMAL PATTERNING FACTOR-LIKE (EPFL) thought contribute (Ikematsu 2017;Holzwart 2018).Crosstalk between important current topic development.In this update, we focus recent advances our understanding fate emphasis signaling.
