| Abstract | The effects of γ-aminobutyric acid (GABA) treatment on parameters of photosynthesis and antioxidant defense system were measured in pepper (Capsicum annuum L.) leaves under low-light (LL) stress. Seedlings exposed to LL stress showed increased chlorophyll content as well as decreased net photosynthetic rate (P n), stomatal conductance (g s), maximum quantum yield of PSII (F v/F m), actual PSII photochemical efficiency (ΦPSII), electron transport rates and photochemical quenching coefficient (q p). However, almost all the photosynthetic parameters above were enhanced markedly in seedlings treated with GABA under LL stress. Moreover, LL stress increased malondialdehyde (MDA) content, superoxide anion radical (O2 ·−) and hydrogen peroxide (H2O2) production. GABA-treated, LL-stressed seedlings exhibited lower MDA, O2 ·− and H2O2 production, and showed an activated antioxidant defense system, including increased activities of superoxide dismutase, catalase, ascorbate peroxidase, glutathione peroxidase, monodehydroascorbate reductase, dehydroascorbate reductase, glutathione reductase, ascorbate and glutathione. Moreover, seedlings subjected to LL stress showed increased endogenous GABA levels, and the level was further improved by application of exogenous GABA. These results suggest that GABA mitigates the LL-induced stress via regulating the antioxidant defense system and maintaining a high level of photochemical efficiency in pepper seedlings. |

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.
