Estructura genética de poblaciones de Oligonychus perseae y Oligonychus punicae (Acari: Tetranychidae) en huertos de aguacate.
Provedor de dados: 32
Autores: Guzmán Valencia, Stephanie.
La identidad y estructura genética de poblaciones de Oligonychus punicae y O. perseae (Acari: Tetranychidae) fue estudiada en siete localidades productoras de aguacate Persea americana var. Hass. La identidad de los ácaros fue determinada morfológica y molecularmente mediante la secuenciación de una fracción del gen Citocromo Oxidasa subunidad I (COI). La variación genética intraespecífica de diferentes poblaciones de ambas especies de ácaros fue estudiada mediante la secuenciación de las regiones ITS1 e ITS2 del rADN.  El análisis filogenético de las secuencias parciales del gen COI separó adecuadamente las dos especies de ácaros, confirmando los resultados de la identificación morfológica. El análisis de las secuencias de las regiones ITS1 e ITS2 del...

Secondary structure of nrDNA Internal Transcribed Spacers as a useful tool to align highly divergent species in phylogenetic studies

Abstract Recently, it has been suggested that internal transcribed spacer (ITS) sequences are under selective constraints to preserve their secondary structure. Here, we investigate the patterns of the ITS nucleotide and secondary structure conservation across the Passiflora L. genus to evaluate the potential use of secondary structure data as a helpful tool for the alignment in taxonomically complex genera. Considering the frequent use of ITS, this study also presents a perspective on future analyses in other plant groups. The ITS1 and ITS2 sequences presented significant differences for mean values of the lowest energy state (LES) and for number of hairpins in different Passiflora subgenera. Statistical analyses for the subgenera separately support...

Characterisation of a novel fruit type found in Ehretia (Ehretiaceae, Boraginales)
Provedor de dados: 16
Autores: Gottschling, M.; Hilger, H.H.
Ehretia (Ehretiaceae, Boraginales) has been divided into two major clades, characterised by fruits with four endocarpids (Ehretia I, including species of Ehretia formerly belonging to Rotula) and by fruits with two endocarpids (Ehretia II, plus E. microphylla (= Carmona retusa) with an undivided endocarp), respectively. Both molecular (ITS1) and morphological data support the recognition of an additional clade, Ehretia III (E. longiflora species group). Its representatives are characterised by four endocarpids (as in Ehretia I), but differ in the presence of distinct lamellae on the abaxial surface of each endocarpid (as in Bourreria, also belonging to Ehretiaceae). However, molecular data suggest a close relationship with Ehretia II. At least three...
