Three-dimensional reconstruction and multiomics analysis reveal a unique pattern of embryogenesis in Ginkgo biloba

PLANT PHYSIOLOGY, Journal Year: 2024, Volume and Issue: 196(1), P. 95 - 111

Published: April 17, 2024

Abstract Ginkgo (Ginkgo biloba L.) is one of the earliest extant species in seed plant phylogeny. Embryo development patterns can provide fundamental evidence for origin, evolution, and adaptation seeds. However, architectural morphological dynamics during embryogenesis G. remain elusive. Herein, we obtained over 2,200 visual slices from 3 stages embryo using micro-computed tomography imaging with improved staining methods. Based on 3-dimensional (3D) spatiotemporal pattern analysis, found that a shoot apical meristem 7 highly differentiated leaf primordia, including axillary buds, present mature embryos. 3D rendering front, top, side views showed 2 separate transport systems tracheids located hypocotyl cotyledon, representing unique embryogenesis. Furthermore, dynamic analysis secretory cavities indicated their strong association cotyledons development. In addition, identified genes GbLBD25a (lateral organ boundaries domain 25a), GbCESA2a (cellulose synthase 2a), GbMYB74c (myeloblastosis 74c), GbPIN2 (PIN-FORMED 2) associated vascular regulation, GbWRKY1 (WRKYGOK 1), GbbHLH12a (basic helix–loop–helix 12a), GbJAZ4 (jasmonate zim-domain 4) potentially involved formation cavities. Moreover, flavonoid accumulation embryos could enhance postgerminative growth seedling establishment harsh environments. Our spatial reconstruction technique combined multiomics opens avenues investigating developmental architecture molecular mechanisms lays foundation evolutionary studies maturation.

Integration of kinks and creases enables tunable folding in meta-ribbons

Matter, Journal Year: 2024, Volume and Issue: 7(9), P. 3007 - 3023

Published: May 15, 2024

Foldable structures find diverse applications. Folding of thin into compact shapes involves the interplay nonlinear mechanics and topology. In this study, we employ discrete models, theoretical analysis, tabletop experiments to systematically investigate geometrically folding process ring-shape elastic ribbons through in-plane kinks out-of-plane creases. We that initiate continuous supercritical bifurcation, while creases trigger abrupt snapping via subcritical bifurcation. Master curves summarize energy landscapes for with varying numbers are obtained. By integrating creases, a "meta-ribbon" can be created, which shows tunable behavior, transitioning from snapping, or vice versa, by strategically engineering angles guided constructed map. As product folding, demonstrate snapping-induced vibration accomplished dynamic as well multistability meta-ribbons saddle-like configurations their transformation.

Abstract Biological pattern formation is essential for generating and maintaining spatial structures from the scale of a single cell to tissues even collections organisms. Besides biochemical interactions, there an important role mechanical geometrical features in generation patterns. We review theoretical principles underlying different types mechanochemical across scales levels biological organization.

Alterations in the Anatomy and Ultrastructure of Leaf Blade in Norway Maple (Acer platanoides L.) Growing on Mining Sludge: Prospects of Using This Tree Species for Phytoremediation

Plants, Journal Year: 2024, Volume and Issue: 13(10), P. 1295 - 1295

Published: May 8, 2024

Alterations in leaf architecture can be used as an indicator of the substrate toxicity level well potential a given plant species phytoremediation polluted areas, e.g., mining sludge. In this work, we demonstrated, for first time, nature and scale alterations at tissue cellular levels occurring Norway maple growing on sludge originating from copper mine Lubin (Poland). The differs other wastes, calamine or serpentine soils, due to extremely high arsenic (As). anatomy predominantly included following: (1) significant increase upper epidermis thickness; (2) decrease palisade parenchyma width; (3) more compact organization; (4) occurrence two three cell layers contrast one control; (5) significantly smaller size cells building parenchyma. At level, mainly local wall thickenings—predominantly lower epidermis—and symptoms accelerated senescence. Nevertheless, many chloroplasts showed almost intact chloroplast ultrastructure. Modifications could symptom morphogenesis but may also related adaptation water deficit stress. thickenings considered defence strategy involved enlargement apoplast volume toxic elements (TE) sequestration alleviation oxidative Importantly, ultrastructure was not markedly disturbed. results suggested that have good potential. However, general shape plant, leaves, senescence indicated experiment. Hence, such substrate, specifically including use maple, should preceded by some amendments—which are highly recommended.

Productivity in strawberry is dependent on carbon assimilation the leaves. The main scenarios for climate change include an increase concentration of CO2 atmosphere and temperature. This review examined relationship between leaf growth temperature strawberry. Leaf follows a linear, sigmoid or Gaussian pattern over season variable depending weather. There was linear with temperatures below 26°C, decrease above 26°C. In other studies, mean lower optimum 90% maximum 18.3° ± 3.9°C, median 19.6°C, range from 7.2° to 22.0°C (N = 11). higher 27.3° 3.6°C, 27.4°C, 21.1° 33.5°C 12). under 30°C 30°C. Limited studies suggest that elevated will not counteract impact high growth. Climate cool areas warm areas. locations contribute yields global warming.
