<p>Se analizó la variación espacio-temporal de la abundancia de las mariposas de la subfamilia Biblidinae (Lepidoptera: Nymphalidae) en un fragmento de Bs-T en la Reserva Campesina La Montaña (RCM), Atlántico, Colombia; desde enero hasta agosto de 2011. Se marcaron cuatro puntos dentro del área de estudio, donde se ubicaron trampas Van Someren–Rydon cebadas con calamar en descomposición, fruta fermentada y con una mezcla de los anteriores cebos. Adicionalmente, se realizó una caracterización de la vegetación por punto, para lo cual se tomaron datos de diámetro a la altura del pecho (DAP), altura y tamaño de la copa para todas aquellas plantas leñosas con DAP mayor o igual a 2,5 cm. Se capturaron 76 individuos agrupados en seis especies y cuatro géneros; destacándose <em>Hamadryas februa</em> (Hübner) como la más dominante con 32 individuos. El mes de marzo presentó la mayor riqueza y abundancia (6 especies y 25 individuos) durantes las primeras lluvias en la zona. El punto 3 presentó los valores más altos de diversidad y abundancia de Biblidinae (5 especies y 37 individuos) y la mayor densidad de árboles (D= 0,28 individuos/m<sup>2</sup>). Se demuestra que la estructura de este grupo de mariposas presenta un patrón temporal y espacial en esta reserva. El análisis de componentes principales demostró que el área basal total (ABT) y la Densidad (D) de plantas leñosas, pueden considerarse como un factor determinante en la distribución y abundancia de las especies de la subfamilia Biblidinae en la RCM.</p><p align="center"><strong>Plant Composition, Feeding Preferences and Abundance of Biblidinae (Lepidoptera: Nymphalidae) in a Tropical Dry Forest Fragment in the Department of Atlántico, Colombia</strong></p><p>The abundance and spatio-temporal variation of butterflies of the Biblidinae subfamily (Lepidoptera: Nymphalidae) in a fragment of Tropical dry forest at the Reserva Campesina La Montaña (RCM), Atlántico, Colombia; from January until August 2011, was analyzed. Within the study area four points were marked; Van Someren-Rydon traps were placed.in each point using rotten squid, fermented fruit and a mixture of both as bait. In addition, a characterization of the vegetation by point was performed, taking data of the diameter to the breast height (DBH), height and size of treetop of all woody plants with a DBH greater than or equal to 2.5 cm. In total 76 butterfly individuals grouped in six species and four genera were captured; being <em>Hamadryas februa</em> (Hübner) the most dominant with 32 individuals. The greatest richness and abundance was recorded in March (6 species and 25 individuals), during the first rains in the study area. The point 3 presented the highest values of diversity and abundance (five species and 37 individuals) of Biblidinae and the higher density of trees (D= 0,28 individuals/m2). The structure of this butterflies group presents a spatio-temporal pattern in this reserve. The principal components analysis showed that the total basal area (ABT) and the density (D) of woody plants, can be considered a determining factor in the distribution and abundance of species of the subfamily Biblidinae at the RCM.</p>

Using one purification procedure, endogenous indol-3-ylacetic acid (IAA), a known regulator of vascular development in woody plants, was characterized by capillary gas chromatography–mass spectrometry in developing secondary xylem of 6 conifers, 16 hardwoods, and 4 additional species of woody plants indigenous to the northern temperate zone. The results suggest IAA may be ubiquitous throughout the Tracheophyta.

BackgroundDaldinia eschscholtziiis a filamentous wood-inhabiting endophyte commonly found in woody plants. Here, we report the identification and characterization of nineD. eschscholtziiisolates from skin scrapings, nail clippings, and blood.MethodsThe nine isolates were identified based on colony morphology, light microscopy, and internal transcribed spacer (ITS)-based phylogeny.In vitroantifungal susceptibility of the fungal isolates was evaluated by the Etest to determine the minimum inhibitory concentration (MIC).ResultsThe nine isolates examined were confirmed asD. eschscholtzii. They exhibited typical features ofDaldiniasp. on Sabouraud Dextrose Agar, with white felty colonies and black-gray coloration on the reverse side. Septate hyphae, branching conidiophore with conidiogenous cells budding from its terminus, and nodulisporium-like conidiophores were observed under the microscope. Phylogenetic analysis revealed that the nine isolates were clustered within theD. eschscholtziispecies complex. All the isolates exhibited low MICs against azole agents (voriconazole, posaconazole, itraconazole, and ketoconazole), as well as amphotericin B, with MIC of less than 1 µg/ml.DiscussionEarly and definitive identification ofD. eschscholtziiis vital to reducing misuse of antimicrobial agents. Detailed morphological and molecular characterization as well as antifungal profiling ofD. eschscholtziiprovide the basis for future studies on its biology, pathogenicity, and medicinal potential.

The Relationship

Two apple [Malus sylvestris (L.) Mill. var. domestica (Borkh.) Mansf.] homologous fragments of FLO/LFY and SQUA/AP1 (AFL and MdAP1, respectively) were analyzed to determine the relationship between floral bud formation and floral gene expression in `Jonathan' apple. The AFL gene was expressed in reproductive and vegetative organs. By contrast, the MdAP1 gene, identified as MdMADS5, which is classified into the AP1 group, was expressed specifically in sepals concurrent with sepal formation. Based on these results, AFL may be involved in floral induction to a greater degree than MdAP1 since AFL transcription increased ≈2 months earlier than MdAP1. Characterization of AFL and MdAP1 should advance the understanding of the processes of floral initiation and flower development in woody plants, especially in fruit trees like apple.

Genes Encoding

Cold acclimation in temperate, woody plants involves distinct changes in gene activity and protein expression. We have been identifying proteins and genes that are associated with seasonal changes in cold hardiness. Seasonal changes in a 60-kDa dehydrin and its corresponding transcript have been identified, as well as seasonal changes in 16- and 19-kDa storage proteins. Further screening of a cDNA library, constructed from cold-acclimated bark tissues collected in December, identified a 700–800-bp clone that was seasonally expressed in Northern blots. The transcript began to accumulate in October, reached a peak in November–December, and then began to decline. By April, the transcript was no longer present in bark tissues. The transcript size indicates that this gene my be related to either the 16- or 19-kDa storage proteins previously identified; however, an amino acid sequence of the protein for comparison has not yet been obtained. Interestingly, the transcript is also expressed during the early stages of peach fruit development. A similar pattern between seasonal expression and fruit development has been observed for a peach dehydrin transcript. Analysis of a partial sequence of the clone has indicated a similarity to genes encoding proteinase inhibitors and thionins (a class of biocidal proteins). More definitive characterization of the gene and identification of its corresponding protein are in progress.

Binding Lectin

The Gastrodia antifungal protein (GAFP-1) is a mannose-binding lectin that can confer increased disease resistance in transgenic tobacco and plum. In all previously generated, transgenic lines, the gene was under the control of the 35SCaMV promoter. In this study, transgenic plum lines were created from seeds derived from open pollination of the cultivar Bluebyrd (BB-OP) with gafp-1 under the control of the polyubiquitin promoter bul409 and evaluated for Phytophthora root rot (PRR) and Root knot nematode (RKN) susceptibility. One of nine transgenic lines synthesizing GAFP-1 exhibited increased tolerance to PRR caused by P. cinnamomi. The same line (BB-OP-1) was also significantly more tolerant to RKN infection caused by Meloidogyne incognita. BB-OP-1 was more resistant to PRR and equally resistant to RKN compared with the cultivar Stanley-derived 4J line, which expresses gafp-1 under the control of the 35SCaMV promoter. GAFP-1 synthesis in BB-OP-1 was not elevated by pathogen infection, suggesting that the bul409 promoter is not inducible in the plum/GAFP-1 system. This study confirms the usefulness of the gafp-1 gene in various cultivars of transgenic plum and establishes that the bul409 promoter is at least equal in effectiveness to the 35SCaMV promoter for gafp-1 expression in transgenic lines of woody plants.
