Abstract:
The early terrestrial fossil record contains numerous Siluro-Devonian problematic Thallophyta which have morphological and habitat characteristics intermediate between the algae and the embryophytic plant kingdom. Three new species of the genus Nematothallus Lang (N. taenia, N. lobata, and N. elliptica) are described from a coaly lens in the Bloomsburg Formation (Ludlow). They are included in the order Nematophytales, which is placed in a new informal taxonomic group, Paraphyta, intended to include enigmatic, terrestrial plant-like fossils. These species designations are based upon the gross morphology of carbonized thalli which consist of an underlying anatomy of flattened tubular elements. The association and attachment of cuticles and axes of ?Prototaxites to Nematothallus is clearly demonstrated in these collections. The morphological and anatomical variety expressed in the numerous fragments of thalli from the deposit implies moderate levels of organic diversity in a “flora” of nonvascular, terrestrial plant-like thallophytes which predates the adaptive radiation of the embryophytes.

Abstract:
Two species of the enigmatic algaChaetocladus, C. ruedemanni(new species) andC. dubius(previously regarded as a graptolite incertae sedis), are described from the Silurian Lockport Group of New York and Ontario, Canada, respectively. A comprehensive investigation reveals that these and otherChaetocladustaxa occur in distinctive Konservat-Lagerstätten in association with other thallophytic algae, annelid worms, and lightly sclerotized arthropods. The sedimentology, taphonomy, and biotic composition ofChaetocladus-bearing deposits indicate that this alga thrived in shallow, stagnant, occasionally storm-agitated marine environments. In these settings, preservation of thallophytic algae and associated soft-bodied animals apparently was facilitated by a combination of obrution, anoxia, and early diagenesis of the burial muds.The morphology ofChaetocladuscorresponds to that characteristic of the green alga order Dasycladales, and it is herein referred to this long-ranging taxon as a representative of a new subtribe (Chaetocladinae, new subtribe) within the tribe Salpingoporelleae (emended herein), family Triploporellaceae (emended herein). This euspondyl, endosporate genus extends the range of the euspondyl dasyclads significantly, from the Early Devonian back to the Middle Ordovician, and bridges an evolutionary gap between early Paleozoic aspondyl, endosporate forms and middle Paleozoic euspondyl, cladosporate forms.

Abstract:
ABSTRACTAlgae or seaweed is the dominant part of marine plants. Morphological-ly, it is categorized as non-vascular plants (Thallophyta) because it has no specific structural configuration such as roots, stems and leaves. This marine algae is found abundantly in the waters of Pulau Nain. Algae from these waters was tested in the laboratory to obtain pharmaceutical preparations to be used as antibacterial active ingredients. This study was carried out to determine the antibacterial activity of the Caulerpa racemosa algae. Antibacterial activity test showed that the test solution of C. racemosa algae has antibacterial activity on all five test bacteria. The size of inhibition zones formed was relatively smaller, when compared to the size of inhibition zone formed by the comparative antibiotic compounds.Keywords: Caulerpa racemosa, seaweed, antibiotic.ABSTRAKAlga atau ganggang laut (seaweed) adalah bagian terbesar dari tumbuhan laut, dimana secara morfologi dapat dikelompokkan kedalam golongan tumbuhan tidak berpembuluh (Thallophyta) karena tidak memiliki perbedaan susunan kerangka seperti akar, batang dan daun. Berdasarkan pengamatan di lapangan, alga laut banyak ditemukan di daerah perairan Pulau Nain. Dari perairan ini selanjutnya dilakukan pengujian secara laboratories untuk memperoleh sediaan farmasi yang digunakan sebagai bahan aktif antibakteri. Penelitian ini dilakukan dengan tujuan untuk menentukan aktivitas antibakteri dari alga Caulerpa racemosa. Hasil pengujian aktivitas antibakteri menunjukkan bahwa larutan uji dari alga C. racemosa memiliki aktivitas antibakteri pada ke 5 bakteri uji yang diujikan. Ukuran zona hambat yang terbentuk relatif lebih kecil, jika dibandingkan dengan ukuran zona hambat yang dibentuk oleh senyawa antibiotika pembanding.Kata kunci: Caulerpa racemosa, ganggang laut, antibiotik.

Les echantillons sont analyses du point de vue petrologique par microspectrofluorimetrie et du point de vue geochimique par pyrolyse et chromatographie en phase gazeuse. La roche mere des hydrocarbures est le silurien; leur generation, suivie de peu par la migration date probablement de la fin du primaire. L'orogenie hercynienne est responsable de la mise en place des pieges structuraux.

Abstract:
L’effet du phoséthy-Al et du métalaxyl a été étudié sur le couple Lycopersicum esculentum Phytophthora capsici, ainsi que celui de l'acide phosphoreux, métabolite actif du phoséthyl-Al sur le même parasite in vitro. L'acide phosphoreux incorporé dans le milieu de culture, à une concentration de 200 µg ml-1, permet de constater en microscopie électronique que, l'organisme fongique ne présente pas un aspect proche de la léthalité. La paroi et le plasmalemme sont affectés et particulièrement les mitochondries. Ce phénomène est également retrouvé, et de façon régulière lorsque le parasite est observé à l'intérieur des feuilles de Tomate traitées au phoséthyl-Al à une concentration de 500 µg ml-1. L'action du métalaxyl sur le P. Capsici à une concentration de 50 µg ml-1, in vivo, est plus accentuée par rapport à celle du phoséthyl-Al, car il entraîne la destruction des mitochondries et altère considérablement la structure du plasmalemme. En comparant l'action du phoséthyl-Al et du métalaxyl in vivo, on constate que ce dernier agit à des doses plus faibles en détruisant le parasite très tôt. Les deux substances permettent d’augmente la résistance des cellules hôtes par la mise en place de corps X, dont la nature est polyphénolique
The effects of fosethyl A1, phosphorous acid and metalaxyl were investigated among Phytophthora capsici Lycopersicum esculentum interaction. Electron microscopie observations showed some slight modification of the cell-wall, plasmalemma and mitochondria of the fungus when cultivated on 200 mg ml-1 phosphorous acid. Similar modification were observed on infected tomato leaf-lets treated with 500 mg ml-1 fosetyl-Al. The in vivo effect of metalaxyl (500 mg ml-1) on P. Capsici is more acute than the fosetyl-Al one. The fungicide affects greatly plasmalemma and mitochondria structure. Low concentrations of metalaxyl were extremely effective vivo in affecting the fungus earlier than fosetyl-Al. The two fungicides enhance host-celle resistance in producing "X bodies. Containing polyphenols

Abstract:
Synthetic dyes cause hazardous health-related problems in humans and affect the biological system underwater. They also have a negative impact on the nutritive value of soils and thereby on crops. Until now there is no effective method to remove the harmful component of dyes from the environment. However, the integrated treatment using bio agents with implication of physical and chemical processes can be effective in the treatment of dye effluents. From the complex azo dyes to their dissociation via thallophytes is a new scope for sustenance. Various studies have supported that laccases have the capability to degrade synthetic dyes that have different chemical structures. Thallophytes have been used to degrade the complex dyes with varying ranges of temperature and pH. Thallophytes have recently been used to treat the textile effluents with effective higher temperature and alkaline pH with decreasing BOD and thus cleaning them from environment in an eco-friendly and cost-efficient manner.
