Changes in photoassimilate partitioning between source and sink organs significantly affect fruit development and size. In this study, a comparison was made of tomato plants (Solanum lycopersicum L.) grown under a low fruit load (one fruit per truss, L1 plants) and under a standard fruit load (five fruits per truss, L5 plants), at morphological, biochemical, and molecular levels. Fruit load red...
Wintersweet (Chimonanthus praecox) is familiar as a garden plant and woody ornamental flower. On account of its unique flowering time and strong fragrance, it has a high ornamental and economic value. Despite a long history of human cultivation, our understanding of wintersweet genetics and molecular biology remains scant, reflecting a lack of basic genomic and transcriptomic data. In this stud...
This study was carried out to characterize antimicrobial, antioxidant and anticancer activities of Michelia champaca seed and flower extracts. The main objective of the present study was to reveal the medicinal values of M. champaca seed and flower for human uses. Antimicrobial property of M. champaca seed and flower extracts were revealed by using two fold microdilution method whereas antioxid...
Land-use intensification and resulting habitat loss are put forward as the main causes of flower visitor decline. However, the impact of urbanization, the prime driver of land-use intensification in Europe, is poorly studied. In particular, our understanding of whether and how it affects the composition and functioning of flower visitor assemblages is scant, yet required to cope with increasing...
APETALA2 (AP2) is best known for its role in the regulation of flower meristem and flower organ identity and development in Arabidopsis. We show here that AP2 also plays an important role in determining seed size, seed weight, and the accumulation of seed oil and protein. We demonstrate genetically that AP2 acts through the maternal sporophyte and endosperm genomes to control seed weight and se...
A Review of Research on Flower-Colored Mutants of Fragrant Cyclamens Induced by Ion-Beam Irradiation
Submit Manuscript | http://medcraveonline.com main component of flower color is anthocyanin, a type of flavonoid [1]. Numerous genes involved in anthocyanin biosynthesis have been analyzed in various plants, and their biosynthesis pathways determined [2,3]. In addition to anthocyanins, flavonols and organic acids also play a role in flower color as ‘co-pigments’ [4]. Fragrant cyclamen cultivars...
Insect floral herbivory can dramatically reduce plant reproductive success. Thus, plants should have evolved mechanisms that minimize the effect of insect herbivores, particularly in monocarpic species that must maximize fitness in a single flowering year. Tolerance is one such mechanism; however, few experiments to date evaluate underlying mechanisms of plant tolerance under natural conditions...
Flower color is a main target for flower breeding. A transgenic approach for flower color modification requires a transgene and a flower-specific promoter. Here, we expressed the B-peru gene encoding a basic helix loop helix (bHLH) transcription factor (TF) together with the mPAP1 gene encoding an R2R3 MYB TF to enhance flower color in tobacco (Nicotiana tabacum L.), using the tobacco anthocyan...
Cultivated for centuries, the varieties of rose have been selected based on a number of flower traits. Understanding the genetic and molecular basis that contributes to these traits will impact on future improvements for this economically important ornamental plant. In this study, we used scanning electron microscopy and sections of meristems and flowers to establish a precise morphological cal...
Phytochemical Analysis of the Leaf, Flower, and Bark of a Medicinal Plant, Crataeva Magna (lour.) Dc
Objective: The aim of this work was to perform preliminary screening of the phytoconstituents present in the leaf, flower, and bark of a valuable medicinal plant, Crataeva magna (Lour.) DC. Methods: Phytochemical analysis of the leaf, flower, and bark extracts was done using various solvent by standard methods as described by Harborne (1973). Results: Six different extracts each for leaf, flowe...
