The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

The Effect of Smoking Treatment on Infection Level, Dormancy, and Physiological Quality of Shallot Seed

Jurnal Teknik Pertanian Lampung, 2022
Plant-derived smokes has antimicrobial activity and have been reported to have the ability to promote germination for various kinds of plant seeds. The purpose of this study was to analyze the effect of coconut shell burning smoke against the level of ...

Water restriction: physiological quality of corn seeds

CONTRIBUCIONES A LAS CIENCIAS SOCIALES, 2023
Text of abstract in plants, stress caused by water deficiency is a major problem in agriculture. Therefore, it is necessary to seek alternatives that aim to maximize yielding with minimal water use and no economic loss. Thus, the objective of the present study was to assess the physiological quality of corn seeds produced under different conditions as ...

Relationship between seed harvesting method and seed physiological quality for a number of Pioneer maize hybrids [PDF]

, 2012
The seed germination and seed vigor of eight Pioneer Hi-Bred maize hybrids were evaluated immediately after harvesting and a year later. The aim was to determine whether the seed showed loss of germination and vigor when shelled mechanically.

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Physical and physiological quality of corn seeds

Research, Society and Development, 2020
The aimed to evaluate the physical and physiological quality, as well the field initial performance of different maize seeds size, produced in two growing environments.  It were used seeds of the Amarelo maize (Zea mays L.) genotype, where it were produced in two growing environments at Rio Grande do Sul, in the crops season of 2016/2017.

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

PHYSIOLOGICAL QUALITY OF STORED PEANUT SEEDS

Engenharia Agrícola
ABSTRACT Storage can reduce seed germination potential and viability, especially in high-lipid species, such as peanuts. This study evaluated the physiological quality of stored peanut seeds from different lineages under long-term storage conditions.

Biomagnification and environmental quality criteria: a physiological approach

ICES Journal of Marine Science, 1993
The method recently introduced in The Netherlands for setting acceptable levels (“quality criteria”) for toxic compounds in the environment is based on the extrapolation of laboratory toxicity data on effects of chronic exposure. With this method a safe concentration for the majority of the species (95%) can be derived (maximum permissible ...
