In plants, basic leucine zipper (bZIP) proteins regulate numerous biological processes such as seed maturation, flower and vascular development, stress signalling and pathogen defence. We have carried out a genome-wide identification and analysis of 125 bZIP genes that exist in the maize genome, encoding 170 distinct bZIP proteins. This family can be(More)
Structured programming principles are not strong enough to control complexity and guarantee high reliability of software at the module level. Stronger organizing principles and stronger properties of components are needed to make significant gains in the quality of software. Practical proposals, based on the definition of normal forms which have a(More)
Loops with multiple-exits and flags detract from the quality of imperative programs. They tend to make control-structures difficult to understand and, at the same time, introduce the risk of non-termination and other correctness problems. A systematic, generally applicable procedure, called loop rationalization, which removes such features and simplifies(More)
The cost of developing and maintaining high quality software remains at a premium. In this paper we introduce a practical approach for enhancement of software quality, based on calculation of strongest postconditions of program components. The method provides a powerful means for detecting and removing by transformation various forms of redundancy and(More)
Protein phosphatases (PPs) play critical roles in various cellular processes through the reversible protein phosphorylation that dictates many signal transduction pathways among organisms. Recently, PPs in Arabidopsis and rice have been identified, while the whole complement of PPs in maize is yet to be reported. In this study, we have identified 159(More)
There is increasing evidence that nicotine is involved in learning and memory. However, there are only few studies that have evaluated the relationship between nicotine and memory reconsolidation. In this study, we investigated the effects of nicotine on the reconsolidation of novel object recognition memory in rats. Behavior procedure involved four(More)
Plant C2H2-type zinc finger proteins (ZFPs) play essential roles in developmental control and stress responses. The whole complement of ZFP genes has been identified in Arabidopsis and rice, while the genome-scale identification and functional analysis of maize ZFPs is not yet reported. Hence, we performed a comprehensive analysis, including gene structure,(More)
Plants respond to survive under water deficit conditions via turning on or off a series of genes that further alter plant physiology and morphology, which allows a plant to tolerate, escape or avoid drought stress. These gene products are either functional (such as aquaporins and the enzymes of osmoprotectant biosynthesis) or regulatory (such as protein(More)
