Karyotype analysis and FISH mapping using 45S rDNA sequences on 6 economically important plant species Anthuriumandraeanum Linden ex André, 1877, Monsteradeliciosa Liebmann, 1849, Philodendronscandens Koch & Sello, 1853, Spathiphyllumwallisii Regel, 1877, Syngoniumauritum (Linnaeus, 1759) Schott, 1829 and Zantedeschiaelliottiana (Knight, 1890) Engler, 1915 within the monocotyledonous family Ara...

In the present investigation attempts were made to estimate genetic parameters for yield and its components in 315 genotypes of cocoyam collected from thirteen aroid growing districts. Plant height, petiole length, petiole breadth, leaf number, leaf length, leaf breadth, LAI, Inflorescence length, peduncle length, spathe length, spathe breadth, corm length, corm breadth, cormel number, cormel l...

UNTIL Marks (1947) described Aedes (Finla)'a) fijiensis from Viti Levu, it had been generally accepted that the representative of the widespread kochi group occurring there was A. kochi (Danitz) itself. The easternmost limit of the latter species is now placed at, or at all events near, Nissan Island, Territory of New Guinea (Marks, 1947). The only indication that A. fijiensis may not be the so...

A new potyvirus, Zantedeschia mild mosaic virus (ZaMMV), was recently identified in calla lily ( Zantedeschia spp.) in Taiwan. The sequenced 3 ′ -terminal region indicated a unique amino acid sequence of ZaMMV, the N terminus of the capsid protein (CP), containing 39 glutamine residues before the DAG motif. In order to obtain antiserum for subsequent studies, a recombinant ZaMMV CP without poly...

We present here the draft genome sequences of bacterial pathogens of the Araceae family, Xanthomonas axonopodis pv. dieffenbachiae LMG 695 and Xanthomonas campestris pv. syngonii LMG 9055, differing in host range. A comparison between genome sequences will help understand the mechanisms involved in tissue specificity and adaptation to host plants.

A circadian rhythm in CO2 production was observed in three cultivars of Anthurium andraeanum Andre (‘Jaya’, ‘Fla-range’, ‘Leonette’) flowers. The rhythmicity was not affected by light, darkness, and detachment. However, the amplitude was dampened in darkness and after detachment. Spadix respiration accounted for 90% of the total flower respiration. Rhythmicity in CO2 production continued after ...
