Abstract:

The zygospore of the saccoderm desmid Spirotaenia diplohelica is described for the first time. The spore is most peculiar, for surrounded by a series of transparent, conical projections. In that feature it very much resembles the zygospore of Spirotaenia truncata. Contrary to Spirotaenia condensata and Spirotaenia obscura, no twin zygospores are produced and walls of empty gametangial cells do not solve in an early stage but tend to stick to the zygospore for some time. In view of those essentially different modes of sexual reproduction it is not to be excluded that species in the traditional

Abstract:

Induction and maturation of the sexual stage (oospores) of the facultative mosquito parasite Lagenidium giganteum (Oomycetes: Lagenidiales) are complex developmental processes regulated by calcium-dependent events. Use of developmentally synchronized cultures of L. giganteum allowed stage-specific disruption of calcium metabolism. A calcium chelator (EGTA), an ionophore (chlortetracycline), and inhibitors of the calcium-binding protein calmodulin (dibucaine, trifluoperazine, chlorpromazine) disrupted several discrete developmental steps associated with oosporogenesis: induction of antheridia,

An overview of sexual reproduction in the Peronosporomycetes leads to the recognition of constant features and variable traits. Variation in characters is accorded different weighting depending on its use for taxonomic identification or phylogenetic systematics. The phylogenetic significance of features of gametangial morphogenesis, such as vacuolation and the patterns of nuclear meioses and abortions, can be related to morphological characters such as the persistence of periplasm and oogonial and oospore wall deposition.

Previously placed in the genus Heydrichia on the basis of morpho-anatomical characters, phylogenetic analyses have shown that this northern New Zealand taxon is not resolved with either Heydrichia or Sporolithon, the two genera currently recognized in this order. Roseapetra displays the key diagnostic features of the order, namely the production of cruciately divided tetrasporangia singly within calcified sporangial compartments.

ABSTRACT A gene from Phytophthora infestans that was previously identified as being induced during the development of sexual spores was also found to be active during asexual sporulation. The gene, M90, was expressed as a 3.1-kb primary transcript containing two introns and was predicted to encode a member of the Puf family of translational regulators. The protein showed up to 51% amino acid identity to other Puf proteins within its 353-amino-acid RNA-binding domain. Little similarity extended beyond this region, as noted for other members of the family. Expression of M90 was measured by using

Several wild species of Ipomoea grow in the central highlands of Mexico. During the summer of 1999, in Metepec, Mexico, blighted leaves and petioles of Ipomoea purpurea were collected from diseased plants and placed in a moist chamber to induce sporulation. Sporangia that formed on the lesions were transferred with a piece of agar to selective rye agar medium (2). Phytophthora ipomoeae was consistently isolated. Species identification was based on sporangial and gametangial characteristics of five cultures grown on rye agar. Sporangia were mainly ellipsoid but occasionally ovoid, semipapillate

Abstract Controlling the life cycle of the green macroalga Ulva (Chlorophyta) is essential to maintain its efficient aquaculture. A fundamental shift in cultivation occurs by transforming the thallus cells into gametangia and sporangia (sporulation), with the subsequent release of gametes and zoids. Sporulation occurrence depends on algal age and abiotic stimuli and is controlled by sporulation inhibitors. Thus, quantification of sporulation intensity is critical for identifying the biotic and abiotic factors that influence the transition to reproductive growth. Here, we propose to determine t

Abstract:

Specimens of Fallacia tenera were collected from the surface sediment at in a river estuary in Japan. Auxosporulation occurred in a rough culture. Morphological structures of vegetative cells and auxospores were observed in detail. The vegetative cells have one H-shaped chloroplast. The striae were interrupted by two depressed lateral sterna internally and partly covered by a finely porous conopeum on the external surface. The lateral sterna and porous conopea formed two more or less curved longitudinal canals connecting with the exterior via opening pores on both sides of a terminal fissure.

Abstract:

The fern family Matoniaceae C. Presl (1847: 32) is a small group composed of only two genera, Matonia R. Brown in Wallich (1829: 16) and Phanerosorus Copeland (1909: 344) with three or four species characterized by rhizomes with polycyclic solenosteles covered with thick uniseriate hairs, anastomosing veins in fertile parts of the lamina, peltate and fugacious indusia, relatively large sporangia and gametangia, and tetrahedral, trilete spores (Kramer 1990, Kato & Setoguchi 1998). The two genera differ from each other in leaf architecture (pedate in Matonia and pinnate in Phanerosorus), hab

Abstract:

In the present paper, we provide a revised, comprehensive description of the sporophyte and gametophyte of the swamp fern, Blechnum serrulatum Rich., from neo- and paleotropical localities. External and internal characters of the sporophyte were analysed, including axes, laminae, pinnae, indusia and spores. Intercellular pectic connections of the parenchyma of the rhizomes are reported for the first time. In stipes, cell walls of the aerenchyma tissue contain filamentous protuberances that are composed primarily of cellulose but contain also fatty substances. The morphology of the gametophyte,

Abstract:

Different concentrations of IAA, GA3, 4CPA, kinetin, and 2,4-D were used to study their effect on growth and reproduction in Dipodascopsis uninucleata. Most of the concentrations of IAA, kinetin, and 2,4-D tested promoted growth, whereas GA3 had no effect. All substances used stimulated lateral branch formation and 2,4-D had the greatest effect. Most concentrations of the growth regulators either inhibited or had no effect on ascus formation; only 10−8 M 4CPA, 10−6 M 2,4-D, and 10−6 M GA3 enhanced ascus formation. The percentage of hyphae with aborted gametangia increased in cultures treated w

A revision of a group of ecorticate species of Chara is presented, on the basis of fresh, pressed and spirit-preserved material. The following seven species are recognised, characterised by a very simple morphology, with few or inconspicuous accessory cells (cortication, stipulodes, bract cells, bracteoles) and large gametangia: Chara australis R.Br., C. lucida (A.Braun) Casanova & Karol comb et. stat. nov., C. porteri Casanova, sp. nov., C. protocharoides Casanova & Karol, nom. nov.

Abstract:

Charophytes are commonly easily recognizable plants irrespective of their size due to the recurrent combination of very similar parts within their thalli. A few species are outstanding due to their unusual whip-like appearance with regularly distributed small nodules on the stems formed with whorls of short and nearly rudimentary branchlets. The central and north-European Chara filiformis A. Braun in Hertzsch (1855: 81) and mainly Middle-Asian C. kirghisorum Lessing (1834: 212) are examples of this distinctive habit. The species differ essentially in gametangia arrangement as well as in their
