Summary: The researchers investigated the rate and trajectory of mitochondria in Arabidopsis thaliana mesophyll cells using confocal laser-scanning microscopy. They discovered that mitochondria migrate through wiggling during their association with chloroplasts, shedding light on the impact of mitochondria-chloroplast interaction on mitochondrial movement.

Summary: Plants relocate their chloroplasts to maximize photosynthesis and reduce photodamage based on light intensities. Another blue light receptor, FLAVIN-BINDING KELCH REPEAT F-BOX1 (FKF1), regulates chloroplast photorelocation by interacting with chloroplast unusual positioning protein 1 (CHUP1). FKF1 overexpression compromises the photodamage avoidance response, while its absence enhances chloroplast movements under high light. JAC1 and THRUMIN1 may play a role in the FKF1-mediated chloroplast avoidance response, but their functional roles need further investigation.

Summary: This experimental study aimed to clarify the protective role of Adiantum capillus-veneris linn plant extracts (ACVL) in female rat reproductive organs intoxicated by carbendazim pesticide (CBZ). The results showed that CBZ toxicity induced histopathological changes and the ACVL plant extract acted as a protective factor by decreasing the synthesis of NF-kappa B-P65.

Summary: The study evaluated the use of leaves from the Adiantum capillus-veneris plant as an adsorbent to remove textile dyes from wastewater. The adsorbent showed better performance compared to commercial adsorbents. It can be concluded that the leaves of the Adiantum capillus-veneris plant are a cost-effective biosorbent that can be used for wastewater treatment and protecting water bodies from toxic pollution.

Summary: Directional movements in plants are regulated by the protein RPT2, which is phosphorylated by phot1 and phot2. This phosphorylation is important for leaf positioning, phototropism, and chloroplast accumulation movement, and highlights the significance of the C-terminal region of NRL proteins in phot receptor signaling.

Summary: The study investigates the relict vegetation in Georgia, which is dominated by the fern Adiantum capillus-veneris and wetland bryophytes. The classification analysis reveals two main vegetation communities, including the Caucasian community and the Colchic community. These communities belong to the Adiantion alliance and require conservation attention due to their rarity and presence of relict and endemic species.

Summary: This study evaluates the possible hepatoprotective effects of Adiantum capillus-veneris L. (ACVL) extract in Carbendazim (CBZ)-treated rats. GC-MS analysis reveals that ACVL extract contains bioactive hydrocarbon components and fatty acids that protect the liver by reducing oxidative stress and decreasing inflammation. Additionally, ACVL extract restores liver function and histopathological markers in CBZ-treated rats.

Summary: This article introduces a significant cellular process, autophagy, which degrades unwanted or damaged macromolecules and organelles through the lysosome or vacuole for recycling. Selective autophagy was found to play a crucial role in regulating chloroplast protein import and enhancing stress tolerance in plants.

Summary: Green light can reduce blue-light-induced chloroplast avoidance movement, but only when presented simultaneously with blue light, while green light alone has no effect on chloroplast position. The action spectrum of green light in duckweed reveals peaks at 510, 550, and 590 nm, and some Arabidopsis mutants are not affected by green light.

Summary: The study investigates the role of cytokinin in the senescence process of detached Arabidopsis leaves. It finds that cytokinin inhibits photosynthesis activity and chlorophyll content while promoting anthocyanin accumulation and ROS production. Additionally, cytokinin stimulates starch accumulation and alters the expression of extracellular cell wall enzyme genes.

Summary: Various proteins in plant chloroplasts are regulated by thiol-based redox processes for light-responsive control. A specific form of phosphofructokinase (PFK), PFK5, is a novel redox-regulated protein that is suppressed upon reduction, while also being activated through oxidization by specific Trx proteins. This redox regulation of PFK5, together with other proteins like FBPase, plays a crucial role in switching light/dark metabolism in chloroplasts.

Summary: FtsH12 plays a crucial role in seedling development of Arabidopsis thaliana, affecting plastid import machinery and chloroplast development. Changes in FtsH12 abundance lead to alterations in protein composition and structure of the chloroplast, impacting overall plant growth and leaf coloration.

Summary: By using the organelle glue technique, we manipulated organelle interactions and controlled the plant metabolome at the pathway level. This study demonstrates the potential for designing plants with desirable metabolic activities by artificially controlling organelle interactions through genetic modification.
