International Classification:

A01H005/00

US Classification:

Abstract:

The present invention involves the isolation and characterization of the first discovered phytochrome-regulated transcriptional factor, a protein designated CCA1 which binds to the promoter region of the chlorophyll binding protein gene (Lhcb1*3) of Arabidopsis. The Lhcb1*3 gene of Arabidopsis is known to be regulated by phytochrome in etiolated seedlings where a brief illumination by red light results in a large increase in the level of mRNA from this gene. A DNA binding activity, designated CA-1, that interacts with the promoter region of Lhcb1*3 was previously discovered in cellular extracts. This binding activity was used to obtain a cDNA clone for a transcription factor that binds specifically to the Lhcb1*3 promoter. Modification of the expression of CCA1 using techniques of genetic engineering results in unexpected changes in the timing of plant flowering. When CCA1 is overexpressed, it appears that the normal circadian rhythms of the plant are disrupted. The plants take a significantly longer time to reach flowering even in the presence of day length conditions that normally induce flowering. Thus, a method of extending vegetative growth and delaying flowering is provided.

Abstract:

Using a metadata of a layer, a prediction factor including a level of participation of the layer in a set of container images is computed. Each container image includes a corresponding set of layers and is usable to configure a container in a container-based virtualized data processing environment. Using a set of levels of participation corresponding to a set of layers, and using a condition in a prediction algorithm, a subset of layers that have to be pre-provisioned at a node is predicted. The subset of layers is adjusted, to form an adjusted subset of layers, by looking ahead at a container requirement of a workload that is planned for processing at a future time. The adjusted subset of layers is caused to be provisioned on the node prior to the future time.
