Iron toxicity: effects on the plants and detoxification strategies

Acta 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

Frontiers 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]

Acta 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

Development of Casparian strip in rice cultivars [PDF]

Plant 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

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

BMC 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

Casparian strip development and its potential function in salt tolerance [PDF]

Plant Signaling & Behavior, 2011
The root system is particularly affected by unfavourable conditions because it is in direct contact with the soil environment. Casparian strips, a specialised structure deposited in anticlinal walls, are characterised by the impregnation of the primary wall pores with lignin and suberin. The Casparian strips in the endo- and exodermis of vascular plant

Functional and Evolutionary Analysis of the CASPARIAN STRIP MEMBRANE DOMAIN PROTEIN Family     [PDF]

Plant Physiology, 2014
AbstractCASPARIAN STRIP MEMBRANE DOMAIN PROTEINS (CASPs) are four-membrane-span proteins that mediate the deposition of Casparian strips in the endodermis by recruiting the lignin polymerization machinery. CASPs show high stability in their membrane domain, which presents all the hallmarks of a membrane scaffold. Here, we characterized the large family

Bioaccumulation of lead (Pb) and its effects in plants: A review

Journal of Hazardous Materials Letters, 2022
Heavy metals (HM) toxicity is becoming a major threat to living organisms in recent years due to the increase in population and anthropogenic activities. Lead (Pb) shares about 10% of total pollution produced by heavy metals.

Transcriptomic, cytological, and physiological analyses reveal the potential regulatory mechanism in Tartary buckwheat under cadmium stress

Frontiers in Plant Science, 2022
Rapid industrialization and urbanization have caused serious cadmium (Cd) pollution in soil. Tartary buckwheat is an important pseudocereal crop with the potential ability to tolerate various stresses.

The structure of the endodermis during the development of pea (Pisum sativum L.) roots

Acta Societatis Botanicorum Poloniae, 2014
It is shown on the basis of cytological studies that during the development of the pea root endodermis, the following structures were formed (in order of appearance): proendodermis, Casparian strips, suberin lamellae and secondary cell walls.
