Plant Biology: Journey to the Center of the Casparian Strip [PDF]

open access: yesCurrent Biology, 2020
Diffusion barriers in roots play an important role in regulating the movement of compounds between the soilenvironment and the vasculature. A new study provides new mechanistic insights into how a pair of copper-binding proteins facilitate the formation of a lignified nanodomain within Casparian strips.

Directed growth and fusion of membrane-wall microdomains requires CASP-mediated inhibition and displacement of secretory foci

open access: yesNature Communications, 2023
Casparian strips are extracellular diffusion barriers in plant roots. Here, Barbosa et al. provide evidence that CASP proteins shape Casparian strips by displacing vesicle tethering factors and organizing cell wall ...

The microstructure of the root of Euryale ferox Salisb. (Nymphaeaceae) from the Russian Far East

open access: yesТрансформация экосистем, 2023
Roots of Euryale ferox Salisb. a rare hydrophyte of the family Nymphaeaceae from the Russian Far East, are anatomically studied. These roots are characterized by a primary structure with typical proportions of histological and topographic zones. There is

CASP microdomain formation requires cross cell wall stabilization of domains and non-cell autonomous action of LOTR1

open access: yeseLife, 2022
Efficient uptake of nutrients in both animal and plant cells requires tissue-spanning diffusion barriers separating inner tissues from the outer lumen/soil. However, we poorly understand how such contiguous three-dimensional superstructures are formed in

Development of Casparian strip in rice cultivars [PDF]

open access: yesPlant Signaling & Behavior, 2011
The development of Casparian strips (CSs) on the endo- and exodermis and their chemical components in roots of three cultivars of rice (Oryza sativa) with different salt tolerance were compared using histochemistry and Fourier transform infrared (FTIR) spectroscopy. The development and deposition of suberin lamellae of CSs on the endo- and exodermis in

Iron toxicity: effects on the plants and detoxification strategies

open access: yesActa Botânica Brasílica, 2022
Iron (Fe) is an essential micronutrient for plants, as a cofactor in multi-heme cytochromes and within iron-sulfur clusters. However, Fe can be toxic at high concentrations.

Plant root suberin: A layer of defence against biotic and abiotic stresses

open access: yesFrontiers in Plant Science, 2022
Plant roots have important functions, such as acquiring nutrients and water from the surrounding soil and transporting them upwards to the shoots. Simultaneously, they must be able to exclude potentially harmful substances and prevent the entry of ...

Comparative vegetative anatomy of Neotropical Goodyerinae Klotzsch (Orchidaceae Juss.: Orchidoideae Lindl.) [PDF]

open access: yesActa Botânica Brasílica, 2020
The Neotropical genera Aspidogyne and Microchilus (Goodyerinae, Cranichideae, Orchidaceae) comprise ca. 200 rainforests terrestrial species. Although species of Goodyerinae are described with similar anatomy to other taxa of Cranichideae, some anatomical

Growth Hormones in Broad Bean (Vicia faba L.) and Radish (Raphanus raphanistrum subsp. sativus L.) Are Associated with Accumulated Concentrations of Perfluoroalkyl Substances

open access: yesToxics, 2023
In this study, we grew radish (Raphanus raphanistrum subsp. sativus L.) and broad beans (Vicia faba L.) in a greenhouse on soils spiked with a mixture of 15 per- and polyfluoroalkyl substances (PFASs) and investigated the association between accumulated ∑

Casparian strip membrane domain proteins in Gossypium arboreum: genome-wide identification and negative regulation of lateral root growth

open access: yesBMC Genomics, 2020
Background Root systems are critical for plant growth and development. The Casparian strip in root systems is involved in stress resistance and maintaining homeostasis. Casparian strip membrane domain proteins (CASPs) are responsible for the formation of
