Exploring Host Resistance against Chilli Leaf Curl Disease in a Tolerant Chilli Genotype.

In tropical countries, combating leaf curl disease in hot peppers has become important in improvement programs. Leaf curl disease is caused by whitefly () transmitted begomoviruses, which mainly include chilli leaf curl virus (ChiLCV). However, multiple begomoviruses have also been found to be associated with this disease.

Anther-derived microspore embryogenesis in pepper hybrids orobelle and Bomby.

Background: Traditional breeding methods have long been employed worldwide for the evaluation and development of pepper cultivars. However, these methods necessitate multiple generations of screening, line development, evaluation, recognition, and crossing to obtain highly homozygous lines. In contrast, in vitro anther-derived microspore culture represents a rapid method to generate homozygous lines within a single generation.

Correlation of stages of microsporogenesis with bud and anther morphology in pepper genotypes through DAPI staining with different levels of mordant in cytological fixative.

The haploid and doubled haploid plants serve as valuable tools for breeders due to their ability to expedite the mapping of genes of agronomic importance, as well as accelerate the breeding cycle for generation of novel hybrids and improved homogenous varieties. Successful anther/microspore culture largely depends on the use of microspores at appropriate developmental stages at the time of culture, which can be specific for each plant species and genotype. In the present study, we described the visible morphological characteristics of flower buds and anthers at different developmental stages to identify the optimal microspore stage within the anther/buds of two pepper hybrids, Indra and Lakshmi.

Genetic Diversity and Population Structure Analyses in Bitter Gourd ( L.) Based on Agro-Morphological and Microsatellite Markers.

Bitter gourd ( L.) is an important vine crop of the Cucurbitaceae family and is well known for its high nutritional and medicinal values. However, the genetic variation remains largely unknown.

Genetic analysis of heat tolerance in hot pepper: insights from comprehensive phenotyping and QTL mapping.

High temperatures present a formidable challenge to the cultivation of hot pepper, profoundly impacting not only vegetative growth but also leading to flower and fruit abscission, thereby causing a significant reduction in yield. To unravel the intricate genetic mechanisms governing heat tolerance in hot pepper, an F population was developed through the crossing of two distinct genotypes exhibiting contrasting heat tolerance characteristics: DLS-161-1 (heat tolerant) and DChBL-240 (heat susceptible). The F population, along with the parental lines, was subjected to comprehensive phenotyping encompassing diverse morphological, physiological, and biochemical heat-related traits under high temperature conditions (with maximum temperature ranging from 31 to 46.

Genetics and Expression Analysis of Anthocyanin Accumulation in Curd Portion of Sicilian Purple to Facilitate Biofortification of Indian Cauliflower.

The present study was undertaken to know the genetics of purple color of cauliflower curds using a Sicilian purple 'PC-1' and a white curding mid-late group genotype of Indian cauliflower. For this, a cross was attempted between 'DC-466' (white curd) and 'PC-1' (purple curd) and observed intermediate level of purple pigmentation on curds in F plants. Segregation of F population (173) revealed that the purple color of the curd was governed by a single gene dominant over white, but the expression of trait was incomplete.

Morphological and molecular changes on cytoplasmic male sterility (CMS) introgression in Asiatic carrot (Daucus carota L.).

MAIN CONCLUSION: 'Petaloid' cytoplasmic male sterility is commonly used as a stable genetic mechanism in carrot hybrid breeding. Its introgression in tropical carrot showed morphometric changes and molecular markers were identified for detection at early stage. Cytoplasmic male sterility (CMS) is the only genetic mechanism in carrot for commercial exploitation of heterosis and production of low cost affordable hybrid seeds.

DNA barcoding for specific and sensitive detection of Cuminum cyminum adulteration in Bunium persicum.

Background: Bunium persicum commonly called as Kala zeera, a very high value herbaceous spice used for medicinal purposes is often adulterated with Cuminum cyminum or Safed zeera, a closely related species. Lack of distinctive morphological features makes the identification of genuine kala zeera from its adulterant difficult, the problem is even exaggerated in case of powdered material.

Methodology: Genomic DNA was extracted from all the plant materials by using CTAB-SDS method (Möller et al.

Conservation and Dispersion of Genes Conferring Resistance to Tomato Begomoviruses between Tomato and Pepper Genomes.

In the present climate change scenario, controlling plant disease through exploitation of host plant resistance could contribute toward the sustainable crop production and global food security. In this respect, the identification of new sources of resistance and utilization of genetic diversity within the species may help in the generation of cultivars with improved disease resistance. Begomoviruses namely, (TYLCV) and (ChLCV) are known to cause major yield losses in several economically important crop plants of the family Solanaceae.

Validation of PCR based detection system for aflatoxin producing molds.

Aflatoxins are polyketide secondary metabolites that are produced by certain fungal species in the Aspergillus section Flavi, particularly Aspergillus flavus and Aspergillus parasiticus which contaminate human food as well as animal feed. These are among the most carcinogenic substances known. Due to the toxic and carcinogenic properties of aflatoxins, there is a need to develop reliable methods to detect the presence of aflatoxigenic Aspergilli in contaminated food and feed.

Food adulteration: Sources, health risks, and detection methods.

Adulteration in food has been a concern since the beginning of civilization, as it not only decreases the quality of food products but also results in a number of ill effects on health. Authentic testing of food and adulterant detection of various food products is required for value assessment and to assure consumer protection against fraudulent activities. Through this review we intend to compile different types of adulterations made in different food items, the health risks imposed by these adulterants and detection methods available for them.

Molecular Detection of Foodborne Pathogens: A Rapid and Accurate Answer to Food Safety.
