Detection of Histone Modifications in Plant Leaves [PDF]

Journal of Visualized Experiments, 2011
Chromatin structure is important for the regulation of gene expression in eukaryotes. In this process, chromatin remodeling, DNA methylation, and covalent modifications on the amino-terminal tails of histones H3 and H4 play essential roles. H3 and H4 histone modifications include methylation of lysine and arginine, acetylation of lysine, and ...

Impact of adding plant leaves powder on compressive strength and corrosion rate of steel mortar [PDF]

E3S Web of Conferences
Incorporating olive leaves powder into mortar may minimize corrosion rates and improve its compressive strength. Different amounts of carbon leaves filings (5 g, 10 g, and 15 g) and olive leaves powder (5 g, 10 g, 15 g, and 20 g) were combined to create ...

Physical Phenomenology of Phyllotaxis [PDF]

, 2011
We propose an evolutionary mechanism of phyllotaxis, regular arrangement of leaves on a plant stem. It is shown that the phyllotactic pattern with the Fibonacci sequence has a selective advantage, for it involves the least number of phyllotactic ...

Surface Density of the Spongy and Palisade Parenchyma Layers of Leaves Extracted From Wideband Ultrasonic Resonance Spectra

Frontiers in Plant Science, 2020
The wide band and air-coupled ultrasonic resonant spectroscopy together with a modified Simulated Annealing metaheuristic algorithm and a 1D layered acoustic-model are used to resolve the structure of plant leaves.

Anthocyanins in perilla plants and dried leaves [PDF]

Phytochemistry, 2018
High-quality perilla leaves are purple on upper and lower surfaces and have a good aroma. The Japanese Pharmacopoeia specifies the content of essential oils in perilla leaves but not that of anthocyanins. Several reports have described the chemical species of anthocyanins in red perilla, but a complete analysis of anthocyanins in perilla has not been ...

Barley plasma membrane intrinsic proteins (PIP aquaporins) as water and CO2 transporters [PDF]

, 2008
We identified barley aquaporins and demonstrated that one, HvPIP2;1, transports water and CO2. Regarding water homeostasis in plants, regulations of aquaporin expression were observed in many plants under several environmental stresses. Under salt stress,

Effect of Quarrying Dust on Leaves Weight and Plants Chlorophyll Content of Pawpaw (Carica papaya), Cassava (Manihot esculenta) and Okra (Abelmoschus esculentus) in Akamkpa, Cross River State, Nigeria

Journal of Applied Sciences and Environmental Management, 2023
Accumulation of dust and other particulate matter on crops could affect photosynthesis, respiration, transpiration and allow the penetration of phytotoxic gaseous pollutants, hence the agricultural crops show stunted growth, minimum leaf area, less ...
