| Abstract | Plant PR10 is one of the pathogenesis related proteins, induced upon exposure to different stress conditions including fungal infection. PR10 proteins have been implicated in fungal disease resistance in some species; however its transcriptional regulation is not well understood. In the present work we cloned a PR10 gene from European plums (Prunus domestica L.) and monitored the quantitative changes in its transcript levels as a result of fungal infection in two varieties. We also studied the possible involvement of the membrane degrading enzyme phospholipase D-alpha (PLDα). In the susceptible variety, ‘Veeblue’, infection with the brown rot fungus Monilinia fructicola induced PLDα and PR10 expression, while in the resistant variety, ‘Violette’, a constitutive expression of PLDα and PR10 transcripts levels were observed. Resistance to M. fructicola also coincides with a sharp decrease in the expression of ABI1, a protein phosphatase and elevated hydrogen peroxide content after infection. Further, inhibition of PLDα by hexanal treatment, up-regulated ABI1 and decreased PR10 expression, suggesting a possible relationship between the two. We further confirm these results in Arabidopsis abi1 mutant that shows a higher level of PR10 transcripts. |

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.
