Plant Science publishes, in the minimum time, papers recommended by its referees in all areas of experimental plant biology, under the four major section headings of Physiology and Biochemistry, Genetics and Molecular Biology, Cell Biology, and General.Papers describing experimental work with multicellular plants and plant-like microorganisms (protists) including algae and fungi, and blue-green algae (cyanobacteria) are appropriate.Submission of manuscripts in the broad areas of biochemistry (including enzymology), bioenergetics, cell biology, development, genetics, molecular biology, physiology and structure in relation to function, as well as fundamental work in these areas related to agriculture and phytopathology are invited.
