Sequence analysis of rDNA intergenic spacer region (IGS) as a tool for phylogenetic studies in Trichoderma spp. 下载免费PDF全文

Different from ribosomal genes, which contain highly conserved sequences that are detected in all organisms, the intergenic spacer of rDNA (IGS) appears to be the most rapidly-evolving spacer region. For this reason we tested this region for phylogenetic studies. This report focuses on the study of IGS sequences of isolates belonging to Trichoderma section (T. viride, T. koningii, T. hamatum, T. erinaceus, T. asperellum) and Pachybasium section (T. harzianum, T. crassum, T. fascicu… 相似文献

Red clover (Trifolium pratense L.) is the third major forage species in Europe, but there is limited information on the biodiversity and the genetic structure
of landraces and natural populations which evolved in this region. The objective of this study was producing such information
for Italian germplasm on the ground of molecular and morphophysiological diversity. The study included 16 Italian natural
populations from a wide range of environments, four landraces representing the four traditional commercial ecotypes, and two
varieties. Eight morphophysiological traits were assessed in a replicated trial under field conditions, whereas two AFLPs
primer combinations with 140 polymorphic markers were recorded on a random sample of 13 genotypes per population. Ordination
and classification results based on morphophysiological data clearly kept track of the type of germplasm (i.e. landrace or
natural population) and its geographic origin, unlike results based on molecular markers. Euclidean distances among populations
based on morphophysiological traits were not correlated with Nei’s genetic distances based on molecular markers according
to Mantel’s test. Geographical distances among landrace or natural population material was correlated with distances based
on morphophysiological traits but not with those based on molecular markers. The average within-population variation estimated
via molecular markers was about 2.6-fold higher than that among populations, preventing an acceptable discrimination among
most populations. On average, natural populations tended to have within-population variation similar to varieties and somewhat
lower than landraces. Our results have implications for collection, conservation, exploitation and registration in a sui generis system of red clover genetic resources. 相似文献

During laboratory tests, mineral oil in water emulsion (2%), containing Brassicaceae seed meals (2 g l−1), induced total mortality (100%) among adult female California red scales on detached orange fruits, whereas only 47.5% of
insect mortality was observed with the same mineral oil when used alone. These results were partially confirmed by two preliminary
field trials. With the aim of improving biodegradability and the environmental impact of the insecticidal formulation, mineral
oil was replaced by a vegetable oil without observing any significant variation of the product’s efficacy. In addition, a
clear “dose-effect” of meal in mineral and vegetable oil was also demonstrated. The formulation, essentially based on oil,
meals and some minor additives, shows the following advantages: (1) high insecticidal activity against an insect pest difficult
to control such as Aonidiella aurantii (Maskell); (2) simultaneous control of several pathogens seems to be possible; (3) non-appearance of resistance phenomena
in plant pathogens; and finally, (5) absence of phytotoxicity. 相似文献

The maize weevil Sitophilus zeamais Motschulsky, 1855 (Coleoptera: Curculionidae) is a worldwide pest on stored products, as maize, wheat and rice grains. However, in South Brazil, these weevils have been found attacking fruits in field conditions. It was reported that adults attack fruits to feeding, but there was no information of oviposition and larval development on these hosts. Furthermore, due to monitoring apple orchards, was observed that some fruits showed distinct kind of punctures, suggesting a oviposition by these weevils. The present study reports first record an unusual behavior of S. zeamais by oviposition and larval development in peach and apple fruits. The study was conducted in laboratory conditions (temperature: 25?±?1 °C, RH: 70?±?10% and photophase of 14 h). Peach and apple fruits were offered to S. zeamais females. The oviposition and duration of immature stages in peach were measured in fruits and in corn grains, used as control observation. The oviposition and larval development occurred in peach and apple fruits, with a development until to adult. The average of egg-to-adult was 47.4 d in peach and and 45.1 d apple fruits, respectively, while in corn grains, its natural host, the duration was 38.2 d. These results show that the damage caused by S. zeamais in peach and apple fruits may be due to oviposition and the development of immature stages. So, the novelty is in demonstrating that the maize weevil does not just feed as an adult opportunistically on the fruits, but can complete a full life cycle using fresh fruits. 相似文献

Control of IBR and BVD should be possible in Europe. Effective vaccines and reliable tools for monitoring are available. Systematic approach and strict implementation of control measures are essential. Voluntary or mandatory programs are ongoing on regional or national level in a lot of countries. Successful programs put pressure on surrounding regions/countries to initiate control program as well. 相似文献

This study aimed to evaluate the effect of concentrate-to-forage ratio (C:F) on the performance, blood profile, and milk physicochemical characteristics of mid-lactation cows fed a corn silage-based diet. Twenty four Holstein cows, with BW 575?±?70 kg, body condition score (BCS) 3.1?±?0.2, milk yield 18.4?±?3.0 kg, and days in milk (DIM) 121?±?21 were randomly allocated into three treatments with C:F ratios of 35:65, 45:55, and 55:45 on a dry matter (DM) basis. Data was submitted to analyses of variance and regression. Increasing C:F from 35 to 55 % linearly enhanced milk production (22 to 23.6 kg day?1) and serum urea nitrogen (16.8 to 19.6 mg/dL), while it linearly reduced lactose and fat in milk (4.8 to 4.6 %; 3.9 to 3.6 %, respectively). Body weight, BCS, milk acidity, ethanol stability, coagulation time, and milk and blood mineral contents did not differ among treatments. During the last period of measurements, increased C:F reduced urinary pH and milk urea nitrogen. Changes of concentrate-to-forage proportion from 35 to 55 % increased milk yield, altered chemical composition without changing BW, BCS, acidity, stability, and mineral content of milk and blood attributes. 相似文献
