Characterization of CYCLOPHILLIN38 shows that a photosynthesis-derived systemic signal controls lateral root emergence
(American Society of Plant Biologists, 2021)
Photosynthesis in leaves generates fixed-carbon resources and essential metabolites that support sink tissues, such as roots. Two of these metabolites, sucrose and auxin, promote growth in root systems, but the explicit ...

H2AK121ub in Arabidopsis associates with a less accessible chromatin state at transcriptional regulation hotspots
(Springer Nature, 2021)
Although it is well established that the Polycomb Group (PcG) complexes maintain gene repression through the incorporation of H2AK121ub and H3K27me3, little is known about the effect of these modifications on chromatin ...

CfrA, a novel carbon flow regulator, adapts carbon metabolism to nitrogen deficiency in cyanobacteria
(American Society of Plant Biologists, 2020)
Cyanobacteria unable to fix atmospheric nitrogen have evolved sophisticated adaptations to survive to long periods of nitrogen starvation. These genetic programs are still largely unknown—as evidenced by the many proteins ...

Interactions of PatA with the divisome during heterocyst differentiation in anabaena
(American Society for Microbiology, 2020)
The Anabaena organismic unit is a filament of communicating cells. Under conditions of nitrogen scarcity, some cells along the filament differentiate into heterocysts, which are specialized in the fixation of atmospheric ...

ALGAEFUN with MARACAS, microALGAE FUNctional enrichment tool for MicroAlgae RnA-seq and Chip-seq AnalysiS
(BMC, 2022)
Background Microalgae are emerging as promising sustainable sources for biofuels, biostimulants in agriculture, soil bioremediation, feed and human nutrients. Nonetheless, the molecular mechanisms underpinning microalgae ...

Nitrogen-regulated antisense transcription in the adaptation to nitrogen deficiency in Nostoc sp. PCC 7120
(Oxford University Press, 2023-06-02)
Transcriptomic analyses using high-throughput methods have revealed abundant antisense transcription in bacteria. Antisense transcription is often due to the overlap of mRNAs with long 5′ or 3′ regions that extend beyond ...

A chloroplast redox relay adapts plastid metabolism to light and affects cytosolic protein quality control
(American Society of Plant Biologists, 2021)
In chloroplasts, thiol-dependent redox regulation is linked to light since the disulfide reductase activity of thioredoxins (Trxs) relies on photo-reduced ferredoxin (Fdx). Furthermore, chloroplasts harbor an NADPH-dependent ...

Biochemical characterization of the amylase activity from the new haloarchaeal strain haloarcula sp. Hs isolated in the odiel marshlands
(Multidisciplinary Digital Publishing Institute (MDPI), 2021)
Alpha‐amylases are a large family of α,1‐4‐endo‐glycosyl hydrolases distributed in all kingdoms of life. The need for poly‐extremotolerant amylases encouraged their search in extreme environments, where archaea become ideal ...

Photorespiration: regulation and new insights on the potential role of persulfidation
(Oxford University Press, 2023-07-24)
Photorespiration has been considered a 'futile' cycle in C3 plants, necessary to detoxify and recycle the metabolites generated by the oxygenating activity of Rubisco. However, several reports indicate that this metabolic ...
