trehalose is an important disaccharide signal metabolite in plants which is involved in various aspects of plant function such as response to stress, photosynthesis and carbon allocation and partitioning. a mutant of arabidopsis lacking trehalose-6-phosphate synthase activity (tps1) accumulates ascorbate. exogenous ascorbate application ameliorates trehalose induced growth inhibition of wild ty...

Chrysanthemummorifolium is one of the four major cut flowers in world, with high ornamental and economic value. Flowering time an important characteristic chrysanthemum that affects its value market. In Arabidopsis, FRUITFULL (FUL) gene plays a key role inducing flowering. Here, we isolated FUL clade MADS-box gene, CmFL3, from inflorescence buds. CmFL3 localized cellular membrane nucleus, showe...

Phosphoinositides play important roles in plant growth and development. Several SAC domain phosphoinositide phosphatases have been reported to be for Here, we show functional analysis of SUPPRESSOR OF ACTIN 6 (SAC6) SAC8 Arabidopsis, a subfamily containing SAC-domain two transmembrane motifs. We isolated an Arabidopsis mutant ncp2 that lacked cotyledons seedling embryo pid, background defective...

Leaf senescence constitutes the last stage of leaf development in plants and proceeds through a highly regulated program in order to redistribution of micro- and macro-nutrients from the senescing leaves to the developing/growing plant organs. Initiation and progression of leaf senescence is accompanied by massive sequential alterations at various levels of leaf biology including leaf morpholog...

Drought stress critically endangers the growth and development of crops. Glutathione S-transferase plays a vital role in response to abiotic stress. However, there are few studies on glutathione maize drought In this study, significantly downregulated expression ZmGST26 roots under was analyzed by qRT-PCR. Promoter analyses showed that were several cis-acting elements related involved oxidative...

Large-scale histone H3 reprogramming during male germline differentiation is conserved between animals and plants. A new report now shows that histone H3 reprogramming also occurs in the female germline of the flowering plant Arabidopsis thaliana.

In a new study, the Papaver rhoeas (poppy family) self-incompatibility system has been transferred into Arabidopsis thaliana, a distantly related plant with a very different floral structure. The simple poppy self-incompatibility system may finally make it possible to introduce this potentially valuable trait into any plant.

Nearest shrunken centroids (NSC) is a popular classification method for microarray data. NSC calculates centroids for each class and "shrinks" the centroids toward 0 using soft thresholding. Future observations are then assigned to the class with the minimum distance between the observation and the (shrunken) centroid. Under certain conditions the soft shrinkage used by NSC is equivalent to a L...
