LIFEGUARD proteins support plant colonization by biotrophic powdery mildew fungi [PDF]

open access: yes, 2013
Pathogenic microbes manipulate eukaryotic cells during invasion and target plant proteins to achieve host susceptibility. BAX INHIBITOR-1 (BI-1) is an endoplasmic reticulum-resident cell death suppressor in plants and animals and is required for full ...

The plant-pathogen haustorial interface at a glance [PDF]

open access: yes, 2020
Many filamentous pathogens invade plant cells through specialized hyphae called haustoria. These infection structures are enveloped by a newly synthesized plant-derived membrane called the extrahaustorial membrane (EHM).

Social context prevents heat hormetic effects against mutagens during fish development

open access: yesFEBS Letters, EarlyView.
This study shows that sublethal heat stress protects fish embryos against ultraviolet radiation, a concept known as ‘hormesis’. However, chemical stress transmission between fish embryos negates this protective effect. By providing evidence for the mechanistic molecular basis of heat stress hormesis and interindividual stress communication, this study ...

Sorting Activities in Plant Cells

open access: yesCHIMIA, 2003
Eucaryotic cells (plants, animals, fungi, etc.) are subdivided in membrane-bound compartments (organelles), such as the nucleus, mitochondria, chloroplasts, vacuoles, etc.

Cell-to-cell movement of mitochondria in plants [PDF]

open access: yesProceedings of the National Academy of Sciences, 2016
Significance We report cell-to-cell movement of mitochondria through a graft junction of two tobacco species, Nicotiana tabacum and Nicotiana sylvestris . The flowers of the N.

Autophagy in cancer and protein conformational disorders

open access: yesFEBS Letters, EarlyView.
Autophagy plays a crucial role in numerous biological processes, including protein and organelle quality control, development, immunity, and metabolism. Hence, dysregulation or mutations in autophagy‐related genes have been implicated in a wide range of human diseases.

Transmembrane potential, an indicator in situ reporting cellular senescence and stress response in plant tissues

open access: yesPlant Methods, 2023
Background Plant cells usually sustain a stable membrane potential due to influx and/or efflux of charged ions across plasma membrane. With the growth and development of plants, different tissues and cells undergo systemic or local programmed decline ...

Cell-to-cell movement of plastids in plants [PDF]

open access: yesProceedings of the National Academy of Sciences, 2012
Our objective was to test whether or not plastids and mitochondria, the two DNA-containing organelles, move between cells in plants. As our experimental approach, we grafted two different species of tobacco, Nicotiana tabacum and Nicotiana sylvestris .

Functional analysis of plant Mei2-like proteins : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Biochemistry at Massey University, Palmerston North, New Zealand [PDF]

open access: yes, 2003
Molecular techniques were used to analyse the function of a novel class of RNA-bindmg proteins in plants, termed Mei2-like. The biochemical function of this class of proteins is unclear Although the conserved presence of three RNA recognition motifs ...

Petal Senescence: New Concepts for Ageing Cells [PDF]

open access: yes, 2009
Senescence in flower petals can be regarded as a form of programmed cell death (PCD), being a process where cells or tissues are broken down in an orderly and predictable manner, whereby nutrients are re-used by other cells, tissues or plant parts.
