Heat-Stress-Induced Changes in Physio-Biochemical Parameters of Mustard Cultivars and Their Role in Heat Stress Tolerance at the Seedling Stage.

In the era of global warming, heat stress, particularly at the seedling stage, is a major problem that affects the production and productivity of crops such as mustard that are grown in cooler climates. Nineteen mustard cultivars were exposed to contrasting temperature regimes-20 °C, 30 °C, 40 °C and a variable range of 25-40 °C-and evaluated for changes in physiological and biochemical parameters at the seedling stage to study their role in heat-stress tolerance. Exposure to heat stress showed detrimental effects on seedling growth as revealed by reduced vigor indices, survival percentages, antioxidant activity and proline content.

Seed coat colour of Indian mustard [ (L.) Czern. and Coss.] is associated with homologs identifiable by targeted functional markers.

Seed coat colour is an important trait in Indian mustard. Breeding for seed coat colour needs precise knowledge of mode of inheritance and markers linked to it. The present study was focussed on genetics and development of functional markers for seed coat colour.

Deciphering the Genetic Inheritance of Tocopherols in Indian Mustard ( L. Czern and Coss).

Tocopherol is vital for the nutritional value and stability of Indian mustard ( L. Czern and Coss) oil; nonetheless, the lack of information on genetic control is hampering its improvement. In this study, six populations (P, P, F, F, BCP, and BCP) of RLC3 × NPJ203 were evaluated in a family block design to evaluate the inheritance pattern, gene effects, and various other genetic parameters of tocopherol content (α, γ, and total), using generation mean analysis.

Genetic diversity and population structure in onion ( L.) accessions based on morphological and molecular approaches.

Unlabelled: Bulb onion is cultivated throughout the world for consumption as vegetable and processed products. Although having high global demand and economic significance, information about genetic diversity and genomic resources is limited. This study investigated the variability of 96 accessions representing seventeen countries.

Agro-morphological and molecular diversity in different maturity groups of Indian cauliflower (Brassica oleracea var. botrytis L.).

The present study analysed the molecular and agro-morphological diversity in a set of 92 diverse cauliflower genotypes and two each of cabbage and broccoli. Field evaluation of the genotypes was done in randomized block design (RBD) at two locations (i.e.

Understanding population structure and detection of QTLs for curding-related traits in Indian cauliflower by genotyping by sequencing analysis.

Curd initiation and development are complex traits and highly responsive for different temperature ranges in cauliflower. The present study was aimed to identify QTLs for eight traits associated with curding behaviour in diverse germplasm of Indian cauliflower. For this, 92 genotypes of cauliflower and 2 each of tropical broccoli and cabbage were genotyped through genotyping by sequencing (GBS).

Unraveling the Relationship Between Seed Yield and Yield-Related Traits in a Diversity Panel of Using Multi-Traits Mixed Model.

The response to selection in any crop improvement program depends on the degree of variance and heritability. The objective of the current study was to explain variance and heritability components in Indian mustard (L). Czern & Coss to recognize promising genotypes for effective breeding.

Exploitation of Novel ICPs for the Management of (Hübner) in Cotton ( L.): A Transgenic Approach.

Cotton is a commercial crop of global importance. The major threat challenging the productivity in cotton has been the lepidopteron insect pest or cotton bollworm which voraciously feeds on various plant parts. Biotechnological interventions to manage this herbivore have been a universally inevitable option.

Development and validation of functional CAPS markers for the FAE genes in and their use in marker-assisted selection.

Low erucic acid is a major breeding target to improve the edible oil quality in . The single nucleotide polymorphism (SNP) in ( and ) gene was exploited to expedite the breeding program. The paralogs of gene were sequenced from low erucic acid genotype Pusa Mustard 30 and SNPs were identified through homologous alignment with sequence downloaded from NCBI GenBank.

Lack of genetic diversity of a critically endangered important medicinal plant Chlorophytum borivilianum in Central India revealed by AFLP markers.

Chlorophytum borivilianum is a traditional medicinal plant distributed throughout the tropics and subtropics. In the present investigation, AFLP analysis was used to assess the genetic similarity among 34 accessions. Nine primer sets of AFLP amplified 612 fragments, of which 246 fragments were found to be polymorphic.

Recombination suppression at the dominant Rhg1/Rfs2 locus underlying soybean resistance to the cyst nematode.

Host resistance to "yellow dwarf" or "moonlight" disease cause by any population (Hg type) of Heterodera glycines I., the soybean cyst nematode (SCN), requires a functional allele at rhg1. The host resistance encoded appears to mimic an apoptotic response in the giant cells formed at the nematode feeding site about 24-48 h after nematode feeding commences.

The nematode resistance allele at the rhg1 locus alters the proteome and primary metabolism of soybean roots.

Heterodera glycines, the soybean cyst nematode (SCN), causes the most damaging chronic disease of soybean (Glycine max). Host resistance requires the resistance allele at rhg1. Resistance destroys the giant cells created in the plant's roots by the nematodes about 24 to 48 h after commencement of feeding.

Re-annotation of the physical map of Glycine max for polyploid-like regions by BAC end sequence driven whole genome shotgun read assembly.

Background: Many of the world's most important food crops have either polyploid genomes or homeologous regions derived from segmental shuffling following polyploid formation. The soybean (Glycine max) genome has been shown to be composed of approximately four thousand short interspersed homeologous regions with 1, 2 or 4 copies per haploid genome by RFLP analysis, microsatellite anchors to BACs and by contigs formed from BAC fingerprints. Despite these similar regions,, the genome has been sequenced by whole genome shotgun sequence (WGS).
