Spinach (Spinacia leracea L.) diseases in Cota (Cundinamarca) and control of downy mildew (Peronosporal farinosa, Byford)
No full textSe identificaron las principales enfermedades en el cultivo de espinaca en Cota (Cundinamarca), considerando tres etapas del ciclo vegetativo: germinación, desarrollo de hojas y cosecha. Durante la germinación, la enfermedad con mayor incidencia fue “Damping-off ” o volcamiento, causado por el complejo Fusarium oxysporum, Pythium sp. y Rhizoctonia solani (8,19%). Durante el desarrollo de hojas, el mildeo velloso (Peronospora farinosa) tuvo la mayor incidencia (32,05%), seguida por hongos foliares: Cladosporium sp., Alternaria sp. y Stemphylium sp. (5,91%) y pudrición blanda de corona, causada por Erwinia carotovora (≤2%). Durante la cosecha, se presentaron manchas foliares causadas por Pseudomonas syringae (5,13%) y la incidencia del mildeo velloso disminuyó a 10,8%. Siendo el mildeo velloso la principal enfermedad en espinaca, se evaluó el efecto preventivo de tres fungicidas químicos (Metalaxil+Mancozeb, Propamocarb y Fosetil Aluminio), tres productos botánicos
comerciales (hidrolatos de manzanilla, ajo-ají y cola de caballo) y tres productos biológicos comerciales (Tri¬choderma harzianum, T. lignorum y Bacillus subtilis) sobre el patógeno en condiciones controladas, utilizando una escala de severidad (0-4). Los productos químicos inhibieron en 100% la germinación de esporangios de P. farinosa y la expresión de la enfermedad en plántulas. Los tres hidrolatos y los hongos antagonistas presentaron poco efecto inhibitorio sobre P. farinosa, mientras que B. subtilis, inhibió en 92% la germinación de esporangios y presentó un valor bajo (1,8), en la escala de severidad, mostrando buen potencial para el control de este patógenoThere were identified the principle spinach diseases in Cota, Cundinamarca, talking into account there stages of the vegetative cycle; germination, leaf development and crop harvest. During the germination, the major incident disease was “Dampiung-Off”, caused by the complex Fusarium axysporum, Pythium sp. And Rhizoctonia solani (8.19%). During the leaf development, downy milde (Peronospora Farinosa) had the major incidence (32.05%), followed by foliage fungi Cladosporium sp, and Stemphylium sp, (5.91%) and rotting of crown, caused by Erwinia carotovora (>2%)

Detection of the pathogenic fungus Cordyceps farinosa in the Thitarodes armoricanus soil-rearing environment based on nucleic acid targets
No full textCordyceps farinosa, an entomopathogenic fungus, infects and leads to high mortality of Thitarodes armoricanus larvae. T. armoricanus larvae die soon after the infection of C. farinose, usually before the colonization of Ophiocordyceps sinensis owing to competitive inhibition and fruiting body formation. Therefore, monitoring C. farinosa in the O. sinensis cultivation environment is critical for minimizing the C. farinosa infection-induced losses. In this study, we initially designed a PCR primer pair (Tar-1F/Tar-1R) through Open Reading Frame prediction and homology comparison of the C. farinosa genome sequence. This primer pair can detect both C. farinosa and Samsoniella hepiali. To further distinguish, primers (ITS5-172/ITS4-95) were then designed to selectively amplify the large ribosomal subunit sequences in the C. farinosa genome. All these primers were applied in combination for detection of C. farinosa in soil samples. The sensitivity reached a detection limit of 1 106 spores/g soil. In addition, these primers can detect the presence of C. farinosa in dead T. armoricanus larval samples. This newly established rapid detection method provides important information for C. farinosa control during O. sinensis cultivation.The presentation of the authors' names and (or) special characters in the title of the pdf file of the accepted manuscript may differ slightly from what is displayed on the item page.

The complete mitochondrial genome of Clonostachys farinosa (Bionectriaceae, Hypocreales)
No full textThe complete mitochondrial genome of Clonostachys farinosa was assembled using the strain CSC22A0184 that was isolated from the lichen Parmotrema clavuliferum. The total length of the mitogenome was 51,551 bp and contained 49 genes: 15 protein-coding genes, two ribosomal RNA genes, 26 transfer RNA genes, and six open reading frames. The GC content of the mitogenome was 28.5% and had a base composition of 36.4% A, 12.6% C, 15.9% G, and 35.1% T. Phylogenetic analysis based on 14 protein-coding genes indicates that C. farinosa is clustered in the family Bionectriaceae. This is the first study of the mitogenome of C. farinosa, which is helpful for understanding the evolution of species within the genus Clonostachys

Distribution Sinetectula farinosa gen. et comb. nov. has a remarkably wide range, from eastern Africa (KF) to Japan (Okutani 2000: 477, pl. 237 fig. 113, as Hindsia nivea), Hawaii (Pease 1860: 142) and the Marshall Islands (KF). Remarks Sinetectula farinosa gen. et comb. nov. is recognisable by its broad, ovate shell in combination with a rather cancellate sculpture. The furrowed edge of the labral lip is typical of the genus, very similar in shape to S. egregia, with a similar tendency to arrange the cusps in pairs, but the slightly deeper basal notches accentuate the basal cusp much less (see Fig. 4B, F). The protoconch is multispiral, consisting of 2 to 2½ whorls, the last whorl with a tiny suprasutural spiral keel (see Fig. 4D). Sinetectula egregia gen. et comb. nov. differs from S. farinosa gen. et comb. nov. by its lower number of protoconch whorls (1 vs 2 to 2½), the slender shape with a higher spire, the weaker sculpture with finer spiral cords and finer axial ribs, the weaker denticles on the columella and the higher number (usually 12) but weaker knobs inside the outer lip.Published as part of Fraussen, Koen & Vermeij, Geerat J., 2021, Sinetectula gen. nov., a new genus of Pisaniidae (Gastropoda: Buccinoidea) from the tropical Indian and Pacific Oceans, pp. 155-176 in European Journal of Taxonomy 748 on pages 166-168, DOI: 10.5852/ejt.2021.748.1351, http://zenodo.org/record/477023
Flavonoids from triplex farinosa
No full textTwo flavonol glycosides, isorhamnetin 3-0-rhamnosyl (1-6) glucopyranoside and isorhamnetin 7-0-glucopyranoside have been isolated from Atriplex farinosa in addition to two known flavanone glycosides, naringin and naringenin 7-0-glucoside. The latter two glycosides have been observed for the first time among the members of the plant family Chenopodiaceae while isorhamnetin 7-0- glucopyranoside has been isolated for the first time in nature. Structures of the isolated flavonoids were elucidated by spectroscopic methods

Holotypus: IRAN: “In jugo Elbrusensi; inter Astrabad et Schahrud”, 6000'–7000' [1830–2130 m], 17.V.1858, Bunge s.n. (G-BOIS [G00330322]; iso-: B [B100241934], K [K000693491], LE [LE00013098], P [P00731148, P00731149, P00731150, P00731151]). Notes. – Of the four isotypes at P, only P00731151 carries the exact date and locality in Bunge’s handwriting “ Matthiola farinosa, m. prope Tasch. 17. mai. 1858”. With that sheet are mounted fragmentary duplicates of P00731148 and P00731149. Except for P00731151, all other duplicates, including the holotype, have printed labels. Unfortunately the holotype is rather fragmentary with flow-er and fruit fragments in a packet, though it has the original species description in Bunge’s handwriting and was the only material examined by Boissier.Published as part of AL-Shehbaz, Ihsan A. & Barriera, Gabrielle, 2019, Typification of Edmond Boissier's Cruciferae (Brassicaceae) names enumerated in Flora Orientalis, pp. 1-193 in Boissiera 72 on page 19, DOI: 10.5281/zenodo.763043

Cycloaspeptides F and G, Cyclic Pentapeptides from a <i>Cordyceps</i>-Colonizing Isolate of <i>Isaria farinosa</i>
No full textCycloaspeptides F (1) and G (2), two new cyclic pentapeptides, and the known cycloaspeptides A (3), C (4), and bisdethiodi(methylthio)hyalodendrin (5) have been isolated from the crude extract of the fungus Isaria farinosa that colonizes Cordyceps sinensis. The structures of 1 and 2 were elucidated primarily by NMR and MS methods. The absolute configuration of 1 was assigned using Marfey’s method on its acid hydrolysate. Compounds 1 and 2 showed cytotoxic effects against HeLa and MCF7 cell lines, displaying the same magnitude of activity toward the MCF7 cells as the positive control 5-fluorouracil
