GENERATION MEAN ANALYSIS OF WATER STRESS TOLERANCE PARAMETERS IN INDIAN MUSTARD [ Brassica juncea (L.) Czern & Coss] CROSSES
Little information is available on the genetics of physiological traits for drought tolerance in Indian mustard. Generation mean analysis was performed using two crosses (Maya x BPR543-2) and (BPR543-2 x BPR2) to study the nature and magnitude of gene effects on seed yield and physiological characters in Indian mustard. The F1, F2, BC1 and BC2 of these crosses, along with P1 and P2, were studie...
متن کاملBioregulatory Role of “thiourea” in Multistress Tolerance of the Indian Mustard (brassica Juncea)
Thiourea (TU) application has been identified as a novel bioregulator technology, for imparting stress tolerance in crop plants. TU application has shown normal growth of Brassica juncea seedlings under salinity stress. In order to study the molecular mechanism underlying TU mediated response, genome wide transcriptome profiling of Brassica juncea seeds was undertaken. In one hour soaking time,...
متن کاملCadmium tolerance and accumulation in Indian mustard is enhanced by overexpressing gamma-glutamylcysteine synthetase.
To investigate rate-limiting factors for glutathione and phytochelatin (PC) production and the importance of these compounds for heavy metal tolerance, Indian mustard (Brassica juncea) was genetically engineered to overexpress the Escherichia coli gshI gene encoding gamma-glutamylcysteine synthetase (gamma-ECS), targeted to the plastids. The gamma-ECS transgenic seedlings showed increased toler...
متن کاملOverexpression of glutathione synthetase in indian mustard enhances cadmium accumulation and tolerance
An important pathway by which plants detoxify heavy metals is through sequestration with heavy-metal-binding peptides called phytochelatins or their precursor, glutathione. To identify limiting factors for heavy-metal accumulation and tolerance, and to develop transgenic plants with an increased capacity to accumulate and/or tolerate heavy metals, the Escherichia coli gshII gene encoding glutat...
متن کاملGrowth response modulation by putrescine in Indian mustard Brassica juncea L. under multiple stress.
Plants, in general, are put to various kinds of stress, biotic and abiotic, both natural and manmade. Infestation by insect pests and diseases, and extreme conditions such as salinity, temperature, etc., as well as heavy metal contamination affect their growth performance. Here, we studied the impact of salinity and heavy metal pollution on the growth performance of Indian Mustard Brassica junc...
