Genetic diversity is important for crop improvement. An experiment was conducted during 2011 to study genetic variability, character association, and genetic diversity among 27 soybean mutants and four mother genotypes. Analysis of variance revealed significant differences among the mutants and moth...

The negative effects of heat stress on maize growth and reproduction is often expressed in terms of significant yield penalty. Germplasm selection based on yield potential along with heat stress adaptive secondary traits, and establishing their interaction under stress helps in identifying suitable ...

Plant growth and development can be adversely affected by cold stress, limiting productivity. The glutathione S-transferase (GST) family comprises important detoxifying enzymes, which play major roles in biotic and abiotic stress responses by reducing the oxidative damage caused by reactive oxygen s...

BACKGROUND: MicroRNAs (miRNAs) are short non-coding RNAs that can influence gene expression via diverse mechanisms. Tomato is a fruit widely consumed for its flavor, culinary attributes, and high nutritional quality. Tomato fruit are climacteric and fleshy, and their ripening is regulated by endogen...

Plants with purple leave attain interest because of their biological importance. A new rice mutant, purple leaf (pl) was isolated from an indicia cultivar Zhenong 34, which was induced by ethyl methane sulfonate (EMS) mutagenesis. The genetic analyses substantiated that pl was corroborated by one re...

Anthocyanins are the resultant end-point metabolites of phenylapropanoid/flavonoid (F/P) pathway which is regulated at transcriptional level via a series of structural genes. Identifying the key genes and their potential interactions can provide us with the clue for novel points of intervention for ...

Isolating and characterizing mutants with altered senescence phenotypes is one of the ways to understand the molecular basis of leaf aging. Using ethyl methane sulfonate mutagenesis, a new rice (Oryza sativa) mutant, brown midrib leaf (bml), was isolated from the indica cultivar ‘Zhenong34’. The bml...

Anthocyanins are plant secondary metabolites with key roles in attracting insect pollinators and protecting against biotic and abiotic stresses. They have potential health-promoting effects as part of the human diet. Anthocyanin biosynthesis has been elucidated in many species, enabling the developm...

Lily belongs to family liliaceae, which mainly propagates vegetatively. Therefore, sufficient number of polymorphic, informative, and functional molecular markers are essential for studying a wide range of genetic parameters in Lilium species. We attempted to develop, characterize and design SSR (si...

Background: Cabbage (Brassica oleracea var. capitata) is popular worldwide for consumption as a leafy vegetable. Premature flowering is triggered by low temperature, and deteriorates quality of cabbage as vegetable. In general, growers prefer late-flowering varieties to assure good quality compact h...

Bacterial blight (BB) is caused by Xanthomonas oryzae pv. oryzae and is one of the most important diseases in rice. It results in significantly reduced productivity throughout all rice-growing regions of the world. Four BB resistance genes have been reported; however, introgression of a single gene ...

BACKGROUND: CONSTANS-like (CO-like, COL) are putative zinc-finger transcription factors known to play vital role in various plant biological processes such as control of flowering time, regulation of plant growth and development and responses to stresses. However, no systematic analysis of COL famil...

Phytoene synthase (PSY) is the first committed enzyme in carotenoid biosynthesis, which plays important role in ripen fruit colour. However, the roles of CaPSY genes are not explained detail in ripen pepper fruit colour. In this study, three CaPSY genes (CaPSY1, CaPSY2 and CaPSY3) were identified th...

Vegetables in Brassica are some of the world’s most commonly cultivated plants and have a wide range of consumable plant organs. Improvement of this group of vegetables is limited at the species level due to limited genetic variability. Interspecies hybridization could be a powerful alternate tool f...

The world's low-lying rice (Oryza sativa) cultivation areas are under threat of submergence or flash flooding due to global warming. Rice plants manifest a variety of physiological and morphological changes to cope with submergence and hypoxia, including lowering carbohydrate consumption, inhibiting...
