2007年1月1日 · Starch is a primary product of photosynthesis in leaves. In most plants, a large fraction of the carbon assimilated during the day is stored transiently in the chloroplast as starch for use during the subsequent night.

2024年12月1日 · We were able to demonstrate that leaf starch degradation by ZmBAM8 enhanced maize drought tolerance. Our work expands the understanding of the process of leaf starch degradation in C 4 crops and provides insights into the significance of leaf starch turnover in plant stress adaptation. This contributes to the development of drought-tolerant ...

The starch amounts in crop leaves were significantly different at different times of the day; the highest starch contents in leaves were seen at 6:00 pm and the lowest at 6:00 am (Table 1). This is simply because leaf starch is synthesized during the day and degraded during the night.

2015年10月1日 · Control of the fine structure of transitory starch synthesized during the day in leaves is required for its normal degradation during the subsequent night. In this study, the molecular structure of transitory starch from Sorghum leaves over the diurnal cycle was characterized using size-exclusion chromatography.

We first investigated the impact of different daylengths on the rate of starch degradation. We measured leaf starch levels of Arabidopsis plants in a 16-h-light/8-h-night regime (long days [LD]) and an 8-h-light/16-h-night regime (short days [SD]). In Arabidopsis, transitory starch was accumulated and broken down almost linearly .

2023年6月1日 · We propose that leaf starch influences the timing of transpiration rhythm through an interplay between the circadian clock and sugars across tissues, while the energetic effect of starch-derived sugars is usually nonlimiting for endogenous stomatal movements.

2007年2月1日 · Starch is a primary product of photosynthesis in leaves. In most plants, a large fraction of the carbon assimilated during the day is stored transiently in the chloroplast as starch for use...

Leaf starch is synthesized in chloroplasts during the day and degraded during the night to produce neutral sugars such as maltose and glucose. Using biochemical and microscopy approaches, we monitored the nocturnal changes of leaf starch in Nicotiana benthamiana.

2016年7月15日 · Starch is synthesised in leaves during the day and is mobilised at night. The rate of leaf starch degradation at night is closely controlled by mechanisms linked to the circadian clock so that starch is eliminated just before the beginning of day.

The present review provides an overview of starch biosynthesis, starch structure and starch degradation in the leaves of plants, focusing on recent advances in each area and highlighting outstanding questions. Starch is a primary product of photosynthesis in leaves.
