Multiple circadian clock outputs regulate diel turnover of carbon and nitrogen reserves

A Flis, V Mengin, AA Ivakov, ST Mugford… - Plant, cell & …, 2019 - Wiley Online Library
Plants accumulate reserves in the daytime to support growth at night. Circadian regulation of
diel reserve turnover was investigated by profiling starch, sugars, glucose 6‐phosphate …

Arabidopsis coordinates the diurnal regulation of carbon allocation and growth across a wide range of photoperiods

R Sulpice, A Flis, AA Ivakov, F Apelt, N Krohn, B Encke… - Molecular plant, 2014 - cell.com
In short photoperiods, plants accumulate starch more rapidly in the light and degrade it more
slowly at night, ensuring that their starch reserves last until dawn. To investigate the …

Response of the Circadian Clock and Diel Starch Turnover to One Day of Low Light or Low CO2

TA Moraes, V Mengin, MG Annunziata, B Encke… - Plant …, 2019 - academic.oup.com
Diel starch turnover responds rapidly to changes in the light regime. We investigated if these
responses require changes in the temporal dynamics of the circadian clock. Arabidopsis …

Circadian control of carbohydrate availability for growth in Arabidopsis plants at night

A Graf, A Schlereth, M Stitt… - Proceedings of the …, 2010 - National Acad Sciences
Plant growth is driven by photosynthetic carbon fixation during the day. Some photosynthate
is accumulated, often as starch, to support nocturnal metabolism and growth at night. The …

Adjustment of diurnal starch turnover to short days: depletion of sugar during the night leads to a temporary inhibition of carbohydrate utilization, accumulation of …

Y Gibon, OE Bläsing, N Palacios‐Rojas… - The Plant …, 2004 - Wiley Online Library
A larger proportion of the fixed carbon is retained as starch in the leaf in short days,
providing a larger store to support metabolism and carbon export during the long night. The …

Photoperiod‐dependent changes in the phase of core clock transcripts and global transcriptional outputs at dawn and dusk in Arabidopsis

A Flis, R Sulpice, DD Seaton, AA Ivakov… - Plant, cell & …, 2016 - Wiley Online Library
Plants use the circadian clock to sense photoperiod length. Seasonal responses like
flowering are triggered at a critical photoperiod when a light‐sensitive clock output coincides …

How plants manage food reserves at night: quantitative models and open questions

A Scialdone, M Howard - Frontiers in Plant Science, 2015 - frontiersin.org
In order to cope with night-time darkness, plants during the day allocate part of their
photosynthate for storage, often as starch. This stored reserve is then degraded at night to …

Understanding circadian regulation of carbohydrate metabolism in Arabidopsis using mathematical models

AAR Webb, A Satake - Plant and Cell Physiology, 2015 - academic.oup.com
C3 plants assimilate carbon by photosynthesis only during the day, but carbon resources
are also required for growth and maintenance at night. To avoid carbon starvation, many …

Nutrient homeostasis within the plant circadian network

MJ Haydon, Á Román, W Arshad - Frontiers in plant science, 2015 - frontiersin.org
Circadian clocks have evolved to enhance adaptive physiology in the predictable,
fluctuating environment caused by the rotation of the planet. Nutrient acquisition is central to …

Downstream of the plant circadian clock: output pathways for the control of physiology and development

S Adams, IA Carré - Essays in Biochemistry, 2011 - portlandpress.com
The plant circadian clock controls many aspects of growth and development, allowing an
individual to adapt its physiology and metabolism in anticipation of diurnal and seasonal …
