Because this process involves sensing the reduction of nutrients and the remobilisation of pod reserves, we investigated the effect on sucrose non-fermenting related kinase 1 (SnRK1) activity during this process. Bean fruits removed from the plant at 20 days after flowering (DAF) demonstrated active remobilisation of nutrients from the pod to the seeds. After 5 days, the pod dry weight was reduced by 50%. The process was characterized by a rapid degradation of starch, with the greatest decrease observed on day 1 after the fruits were removed. The pod nutrients were insufficient for the needs of all the seeds, and only some seeds continueFrontiers in plant science196https://www.ebi.ac.uk/biostudies/studies/S-EPMC4030202biostudies-literatureThe activity of SnRK1 is increased in Phaseolus vulgaris seeds in response to a reduced nutrient supply.PMC4030202Martinez-Barajas ECoello PfalseThe activity of SnRK1 is increased in Phaseolus vulgaris seeds in response to a reduced nutrient supply.Phaseolus vulgaris seeds can grow and develop at the expense of the pod reserves after the fruits have been removed from the plant (Fountain etal., 1989).
