We isolated and characterized a pollen-preferential gene, BAN102, from Chinese cabbage and analyzed the activity of its promoter. There were three or four copies of the BAN102 gene in the Chinese cabbage genome that specifically expressed in pollen and pollen tube. There were 2137 bp of BAN102

Mapping and resequencing of two allelic early bolting mutants ebm5-1 and ebm5-2 revealed that the BrSDG8 gene is related to bolting in Chinese cabbage (Brassica rapa ssp. pekinensis). Bolting influences the leafy head formation and seed yield of Chinese cabbage therefore being an important agronomic

Five cis-clerodane diterpenoids, stephanialides A-E, along with seven known cis-clerodanes, scaparvins A-C, parvitexins B and C, 3-chloro-4-hydroxy-parvitexin A, and scapanialide B, were isolated from the Chinese liverwort Scapania stephanii. Their structures were established unequivocally on the

The Brassica rapa oxidosqualene cyclase Bra032185 makes 60% astertarone A (1) and 20 minor triterpenes (0.1-11%). Mechanistic analysis indicates the absence of an enol intermediate to generate the 4 S epimer of 1, unless workup involves saponification. Bra032185 and its closest Arabidopsis thaliana

Mitochondria are the energy sources of plant cells and are involved in regulating cell development. Ubiquinol-cytochrome c reductase iron-sulfur protein, which is necessary for mitochondrial respiration, is a subunit of mitochondrial electron transport chain multimeric enzyme complexes. To better

Three Arabidopsis cDNAs, MAM1, CYP79F1, and CYP83A1, required for aliphatic glucosinolate biosynthesis were introduced into Chinese cabbage by Agrobacterium tumefaciens-mediated transformation. The transgenic lines overexpressing MAM1 or CYP83A1 showed wild-type phenotypes. However, all the lines

Plant WRKY transcription factors are known to regulate various biotic and abiotic stress responses. In this study we identified a total of 30 putative WRKY unigenes in a transcriptome dataset of the Chinese wild Hazel, Corylus heterophylla, a species that is noted for its cold tolerance. Thirteen

Malate dehydrogenases (MDHs) are key metabolic enzymes that play important roles in plant growth and development. In the present study, we isolated the full-length and coding sequences of BraMDH from Chinese cabbage [Brassica campestris L. ssp. pekinensis (Lour) Olsson]. We conducted bioinformatics

Piriformospora indica, an endophytic fungus of the order Sebacinales, interacts with the roots of a large variety of plant species. We compared the interaction of this fungus with Chinese cabbage (Brassica campestris subsp. chinensis) and Arabidopsis seedlings. The development of shoots and roots of

Leaf color mutants are widespread in higher plants and can be used as markers in crop breeding or as important material in understanding the regulatory mechanisms of chlorophyll biosynthesis and chloroplast development. A stably inherited plant etiolated mutation (pem) was obtained from its

Indole glucosinolates (IG) play important roles in plant defense, plant-insect interactions, and stress responses in plants. In an attempt to metabolically engineer the IG pathway flux in Chinese cabbage, three important Arabidopsis cDNAs, CYP79B2, CYP79B3, and CYP83B1, were introduced into Chinese

CONCLUSIONS Exposure of Arabidopsis callus to microgravity has a significant impact on the expression of proteins involved in stress responses, carbohydrate metabolism, protein synthesis, intracellular trafficking, signaling, and cell wall biosynthesis. Microgravity is among the main environmental

Phytocyanins (PCs) are a plant-specific family of small copper-containing electron transfer proteins. PCs may bind with a single copper atom to function as electron transporters in various biological systems, such as copper trafficking and plant photosynthesis. Evidence indicates that PCs may also

In our previous study, we identified a Rosa chinensis heat shock protein (HSP) gene, RcHSP17.8, which was induced by abiotic stresses, such as high temperature and osmotic stress. To analyze the expression of RcHSP17.8 and the function of cis-acting elements in the promoter region, a 1,910 bp

Nucleotide-sugar transporters (NSTs) form a family of structurally related transmembrane proteins that transport nucleotide-sugars from the cytoplasm to the endoplasmic reticulum and Golgi lumen. In these organelles, activated sugars are substrates for various glycosyltransferases involved in oligo-
