Host-driven morphological variability in Orobanche crenata (Orobanchaceae)
2018
Studies on interactions between Orobanche species and their hosts are mainly focused on resistance, radical interactions, and haustorium development. The influence of the host plant on morphology of the parasite under environmental controlled conditions is not reported in the literature. With the aim of filling this gap, the results of cultivation experiments of Orobanche crenata on Vicia faba, V. sativa, Pisum sativum, Cicer arietinum, and Lathyrus clymenum are presented. The tested population of O. crenata infected all the studied hosts but showed preferences toward Vicia and Pisum and, in particular, toward a foreign V. sativa cv. The higher resistance of the evaluated local cv. could be…
Research onOrobanche crenata management in sicily from the 19 th to the early 20 th century
2006
In order to offer hints for new research, the agronomic techniques used to manageOrobanche crenata in Sicily in the late 19 th and early 20 th Century are examined; the publications in which they were originally described can be obtained only with difficulty. Hand pulling, resistant cultivars and late sowing are the techniques used nowadays. Screening for resistance to broomrape of the traditional cultivars of broad bean, and for the influence of sowing density on broomrape infestations, is still to be done.
A proteomic approach to studying plant response to crenate broomrape (Orobanche crenata) in pea (Pisum sativum)
2004
Abstract Crenate broomrape ( Orobanche crenata ) is a parasitic plant that threatens legume production in Mediterranean areas. Pea ( Pisum sativum ) is severely affected, and only moderate levels of genetic resistance have so far been identified. In the present work we selected the most resistant accession available (Ps 624) and compared it with a susceptible (Messire) cultivar. Experiments were performed by using pot and Petri dish bioassays, showing little differences in the percentage of broomrape seed germination induced by both genotypes, but a significant hamper in the number of successfully installed tubercles and their developmental stage in the Ps 624 compared to Messire. The prote…
The status of Orobanche crenata in Sicily and preliminary observations on Orobanche crenata susceptibility in Vicia faba
2013
Since more than 10 years we are recording Orobanche crenata populations variations and testing traditional remedies to assess their applicability in a low impact agriculture that may be applied also in developing countries. Starting from the observation that often in C Sicily dense fields of Broadbean show lower Broomrape infestation, we did some preliminary observations on Orobanche crenata susceptibility in Vicia faba var. faba and Vicia faba var. equina with different agricultural techniques. First results show a higher resistance of the latter sowed at higher densities.
Differential expression proteomics to investigate responses and resistance to Orobanche crenata in legumes
2007
International audience; In order to study the plant response to parasitic plants and the molecular basis of the resistance we have used a proteomic approach. The root proteome of two accessions of the model legume Medicago truncatula and crop pea displaying differences in their resistance phenotype, in control as well as in infected plants have been compared. We report quantitative as well as qualitative differences in the two-dimensional gel electrophoresis (2-DE) maps between plant genotypes and treatments (control, non-infected, and infected). Differential spots spots were successfully identified by peptide mass fingerprinting (PMF) following MALDI-TOF mass spectrometry. Many of the prot…
