Disease relevance of Kalanchoe

• A slight reduction in the virulence of these mutant Agrobacterium strains on red potato plants, but not on tobacco, tomato, kalanchoe, or sunflower plants, was observed [1].
• Quercitrin (quercetin 3- O-alpha- L-rhamnopyranoside), one of the constituents of the biologically active aqueous extract obtained from Kalanchoe pinnata, is demonstrated to be a potent antileishmanial compound (IC50 approximately 1 microg/mL) with a low toxicity profile [2].
• Flavonoids are known inhibitors of thyroid peroxidase (TPO) and some are components of Kalanchoe brasiliensis, a plant used in popular medicine to treat tissue injuries, enlarged ganglia and peptic ulcer [3].

High impact information on Kalanchoe

• Introduction of the wide host range (WHR) virA gene is essential for extending the host range to Kalanchoë daigremontiana [4].
• Electrophysiological studies using the patch-clamp technique were performed on isolated vacuoles from leaf mesophyll cells of the crassulacean acid metabolism (CAM) plant Kalanchoë daigremontiana to characterize the malate transport system responsible for nocturnal malic acid accumulation [5].
• Shoots of seven CAM species (Aloe vera, Hylocereus monocanthus, Kalanchoe beharensis, Kalanchoe daigremontiana, Kalanchoe pinnata, Vanilla pauciflora, and Xerosicyos danguyi) and two C(3) species (teak [Tectona grandis] and Clusia sp.) were grown in a cuvette, and net CO(2) exchange was monitored for up to 51 d [6].
• Adenosine 3':5'-cyclic monophosphate in higher plants: Isolation and characterization of adenosine 3':5'-cyclic monophosphate from Kalanchoe and Agave [7].
• All five exconjugants exhibited virulence on carrot, sunflower and kalanchoe plants [8].

Chemical compound and disease context of Kalanchoe

• Cardiac glycoside poisoning was produced in calves given (in descending order of toxicity) flower heads of the hybrid Bryophyllum (Kalanchoe) daigremontianum x B. tubiflorum, of B. pinnatum, of B. tubiflorum (from previous work), whole plant of B. fedtschenkoi, flower heads of B. daigremontianum and whole plant of B. proliferum [9].

Biological context of Kalanchoe

• Plasmids containing defined regions of the virD operon were introduced into this strain, and virulence was tested by the strains' abilities to form tumors on Kalanchoe leaves, tomato stems, and potato tubers [10].
• Contribution of C3 carboxylation to the circadian rhythm of carbon dioxide uptake in a Crassulacean acid metabolism plant Kalanchoë daigremontiana [11].
• Correlation of epiphyllous bud differentiation with foliar senescence in crassulacean succulent Kalanchoe pinnata as revealed by thidiazuron and ethrel application [12].
• Rapid purification and reconstitution of a plant vacuolar ATPase using Triton X-114 fractionation: subunit composition and substrate kinetics of the H(+)-ATPase from the tonoplast of Kalanchoë daigremontiana [13].

Associations of Kalanchoe with chemical compounds

• Perturbations of malate accumulation and the endogenous rhythms of gas exchange in the Crassulacean acid metabolism plant Kalanchoë daigremontiana: testing the tonoplast-as-oscillator model [14].
• Here we report that by growth of chvB mutant cells in tryptone-yeast extract medium supplemented with 7 mM CaCl2 and 100 mM NaCl, the mutant cells become motile, attach to pea root hair tips, and are virulent on Kalanchoë leaves [15].
• Heat shock-controlled IAM and IAA synthesis was tested on two levels: biochemically by measuring IAM and IAA levels in Kalanchoe stem segments infected with the two constructs, and morphologically by IAA-dependent root formation on Kalanchoe plants, on carrot discs and on tobacco leaf fragments [16].
• Isolation and structure determination of daigremontianin, a novel bufadienolide from Kalanchoe daigremontiana [17].
• In the two Kalanchoë species, isocitrate levels were higher than citrate levels; the reverse was the case in pineapple [18].

Gene context of Kalanchoe

• One subclone containing only virE1 and virE2 as well as upstream promoter sequences was sufficient to restore full virulence on the host plant Kalanchoe daigremontiana [19].
• The three triple gene blocks (ORF2-4), ORF5 (coat protein) and 3'-proximal 16 kDa ORF6 genes were further analyzed, and phylogenetic trees for the coding regions indicate that the LSV was the most closely related to Kalanchoe latent virus and BlScV [20].
• Identification of multiple PEPC isogenes in leaves of the facultative Crassulacean acid metabolism (CAM) plant Kalanchoe blossfeldiana Poelln. cv. Tom Thumb [21].
• Day and night forms of phosphoenolpyruvate carboxylase (EC 4.1.1.31) (PEPC) were extracted from leaves of the CAM plants Kalanchoe daigremontiana, K. tubiflora and K. blossfeldiana previously fed with [32P] labelled phosphate solution [22].
• In the present work we have characterized the ATPase activity associated with vacuoles of the crassulacean-acid-metabolism plant Kalanchoë daigremontiana and compare it with other phosphohydrolases [23].
