In 1970s it was thought that two species of ‘farro’, namely emmer (Triticum dicoccon Schrank) and einkorn (T. monococcum L.), were no longer present in Italy, but in 1981, some populations were discovered in a mountain area of the Appennino Sannita
(central southern Italy). In 2006/2007 three monitoring missions were carried out to check the current situation of these
ancient hulled wheats, specifically in the same areas where they were formerly collected. The same zones were also investigated
by both paleo-ethnobotany and agrobiodiversity points of view. The results of this research have shown that nowadays einkorn
is completely extinct while emmer is still cultivated in very few traditional farms, mainly as a fodder crop. A strong genetic
erosion was detected also for emmer and several nowadays samples were contaminated by seeds of modern spelt (T. spelta L.) varieties. In the present study the causes of this genetic erosion and which safeguarding actions to be undertaken are
discussed. 相似文献

The methodology for the inclusion of tebuconazole (TBC) in beta-cyclodextrin (betaCD), spectroscopic characterization of the inclusion complex, and its activity for the control of a major soilborne disease of wheat caused by Fusarium culmorum are reported. Controlled release measured by chemical shift of the diagnostic protons H(3) and H(5) of betaCD confirmed stability of the complex at the solid state and in aqueous solution. Greenhouse and field experiments were conducted on durum wheat (Triticum durum cv. Prometeo) sown in substrate or in soil artificially infested with a virulent strain of F. culmorum. The inclusion complex betaCD-TBC, applied as seed dressing in combination or not with carboxymethylcellulose, reduced the disease incidence caused by F. culmorum and improved grain yield, showing effects that were generally comparable to those observed upon application of a commercial formulation of TBC. In the field experiment, only seed treatment with the inclusion complex betaCD-TBC allowed yield that was not different from that obtained from the uninoculated control. These results prove that by the use of the betaCD-TBC complex it is possible to obtain release of TBC and bioavailabilty of the fungicide without compromising its effectiveness. 相似文献

In this work we detected the extent of variability at nuclear and cytoplasmic DNA level of regenerated plants belonging to
Solanum genotypes with a different genetic background and somatic chromosome number. As for the nuclear characterization, a total
of 66 (18.5%) polymorphic bands were scored using 13 ISSR primers on 45 randomly selected regenerants. Our results show that
the regenerants obtained from clone cmm 1T and, at lower level, those from cph 1C are unstable under in vitro conditions or
rather more prone to in vitro-induced stress leading to somaclonal variation than the other genotypes used. Two types of changes
were observed: disappearance of parental ISSR fragments, termed “loss”; appearance of novel ISSR fragments, termed “gain”.
The most frequent event occurring in the regenerants was the loss of fragments (41 bands). Regenerated plants were analyzed
with seven plastid universal primers to determine the cytoplasmic composition at chloroplast level. All cpDNA primer pairs
tested produced amplicons of the same size in all genotypes analyzed and no polymorphic fragments were observed with any universal
primers used. Our results show that under in vitro culture conditions genotype affects the integrity of the genome. In addition,
the absence of polymorphism at plastid level confirms the greater genetic stability of cytoplasmic DNA. 相似文献

The aim of this study was to evaluate the effect of exogenous progesterone supplementation on superovulatory response in buffaloes
that has undergone a multiple ovulation program. Fourteen Mediterranean buffaloes were divided into two groups and received
a 4-day decreasing dosage of an equal mixture of 500 IU of FSH and LH starting on day 8 of the cycle. In group A (n = 7) a progesterone-releasing intravaginal device was removed on day 8, whereas in group B (n = 7) it was left till day 10, when PGF2a {\hbox{PG}}{{\hbox{F}}_{{2}\alpha }} was administered. Eighty hours later, buffaloes were artificially inseminated and after 6 days they undergone uterine flushing.
A higher (P < 0.05) number of corpora lutea (8.3 vs. 5.7) and embryo/flushing/buffalo (2.3 vs. 1.3) were recorded in group B vs. group
A if responsive buffaloes are considered (n = 12) and the number of corpora lutea was highly correlated with the number of embryos (r = 0.65; P < 0.05). In conclusion, progesterone supplementation during the first 2 days of the superovulation treatment seems to enhance
the recovery rate in buffalo species. A high ovulation rate, associated with a high number of corpora lutea, can represent
a parameter for estimating embryo recovery. 相似文献

Anthrax is a non-contagious disease, known since ancient times. However, it became a matter of global public interest after the bioterrorist attacks in the U.S.A. during the autumn of 2001. The concern of politicians and civil authorities everywhere towards this emergency necessitated a significant research effort and the prevention of new bioterrorist acts. Anthrax is primarily a disease that affects livestock and wildlife; its distribution is worldwide; and it can represent a danger to humans but especially more so when it occurs in areas considered to be free and in atypical seasons and climatic conditions. The atypicality of the phenomenon may lead health workers to misdiagnose and, consequently, an inappropriately manage of affected carcasses with a consequent and inevitable increase in the risk of human infection. This article emphasises the importance of paying increasing attention to this zoonosis. The biggest risk is its underestimation. 相似文献

In the world lentil is grown on more than 3 million hectares and is one of the most important, low-cost, food source of protein.
In Italy lentil has been cultivated since ancient times, but in the last decades its cultivation has been confined to marginal
areas, small islands and hilly, mountainous areas of central and southern Italy. Local varieties are still common and are
often greatly appreciated for their taste and cooking qualities. Several accessions from the Santo Stefano di Sessanio area,
Abruzzo Region, were collected and phenotypically and genotypically characterized in order to look for the existing variability
within and between populations. Image analysis of seeds was also used. Populations grown in Santo Stefano di Sessanio and
in the neighbouring area basically share most of their characteristics. However, some of the accessions anonymously gathered
from the local market were shown to be different from those collected from farmers. The paper reports and discusses how this
local product needs be characterized and promoted in order to avoid fraud that could negatively affect the local economy and
put valuable, adapted, genetic resources at risk of erosion. 相似文献

When changing from spatially random to spatially connected appearances as conditions become wetter in their seasonal time dynamics, soil moisture spatial patterns show a behaviour similar to phase transition processes. In a previous work, once implemented an ad-hoc methodology, we have demonstrated that such a phase change shows critical point behaviour. Moreover, the value of the critical probability seems to be an intrinsic characteristic of a catchment, being insensitive to renormalization (rescaling), as well as to model parameterization. 相似文献

A common seagull (Larus fuscus) was found near the southern coast of Italy by the veterinarians of the local wild animal rescue center. Physical examination of the bird revealed an ulcerated mass involving a majority of the oral cavity; the mass did not allow for normal feeding. After the bird died necropsy was performed and the mass was histologically and immunohistochemically examined. The morphology and the immunoreactivity for Melan-A and S-100 antigens led to a diagnosis of malignant melanoma. This is the first case of malignant melanoma described in a seagull, and herein we compare the characteristics of the present case with malignant melanoma already described in domestic animals. 相似文献
