| Abstract | In France, oilseed rape is getting highly infected since 1990 by the branched broomrape Phelipanche ramosa (L.) Pomel. Branched broomrape infection causes serious yield losses ranging from 5 to 100 %, notably in the Mediterranean area. P. ramosa is parasiting the plant roots. The growth of P. ramosa on Brassicaceae weeds has not been studied quantitatively so far, except for the model species Arabidopsis thaliana. Since P. ramosa has a fast development rate on the fast-growing A. thaliana, P. ramosa development should be slower on other slower-growing Brassicaceae species. Here, we cultivated in the laboratory seven Brassicaceae weed species including Capsella bursa-pastoris, Capsella rubella, Cardamine hirsuta, Lepidium campestre, Lepidium draba, Sinapis arvensis and A. thaliana as control, during 3 weeks. We counted the number of P. ramosa individuals that have reached the following growth stages: germination, attachment, tubercle, bud and underground stem. We then assessed the development rate of P. ramosa by calculating the odds ratio of attachment or higher development stages of P. ramosa on Brassicaceae, with A. thaliana as the reference. We found that five Brassicaceae species had an odds ratio ranging from 0.9 to 2.4. These ratios are thus similar or higher than that of the A. thaliana reference. This finding shows for the first time that P. ramosa develops faster on the five Brassicaceae species. This finding is also unexpected because A. thaliana is a fast-growing plant, whereas the five Brassicaceae species have a longer life cycle. Therefore, this observation demonstrates for the first time that P. ramosa development depends on others factors than the speed of plant host development. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
