Abstract Age-related declines in fertilization success have been reported for a wide range of species. The fertilization of parasitic wasps is closely related to egg production and sperm storage. Aenasius bambawalei (Hymenoptera: Encyridae) is a key parasitic wasp of the important invasive mealybug Phenacoccus solenopsis (Hemiptera: Pseudococcidae). The female offspring ratio of this parasitic wasp was declined with parental age in mass rearing under laboratory conditions. To investigate the molecular mechanisms involved in the reproduction of A. bambawalei, an extensive analysis of the impact of age on transcriptome profile of mated ovaries of this wasp was performed by comparing the gene… More >

Abstract Drought is the main abiotic stress that restricts wheat production. The rapid development of sequencing technology and its widespread application to various fields have revealed the structural characteristics and regulation of related genes through gene expression analysis. Here, we studied responses of wheat plants under drought and re-watering conditions, using morphological and physiological indicators. Moreover, a transcriptome analysis was conducted on Jingmai 12, a drought-resistant wheat strain, to explore the mechanism underlying the response of drought-resistant wheat seedlings to drought stress at the transcriptome level. Drought stress caused morphological and physiological changes in both drought-resistant and -sensitive varieties, but to… More >

Abstract The halophilic unicellular green alga Dunaliella salina is characterized as the distinct tolerance to high salt in the field. Normally the organism is concurrently subjected with salt and alkali stress, but the feature of D. salina in response to high alkali stress was not investigated before. In this study, we used high pH stress to simulate high alkali stress and found D. salina also showed tolerance to high alkali stress, even grown under pH at 11.0, with high cell density and chlorophyll biosynthesis. High-throughput transcriptome analysis revealed the dramatically different expression of genes associated with nitrogen metabolism, lipid and β-carotene… More >

Abstract Abiotic stresses such as drought, heat, cold, nutrient deficiency, excess salt and hazardous metals can hamper plantgrowth and development. Intensive agriculture of only a few major staple food crops that are sensitive and intolerant to environmental stresses has led to an agrarian crisis. On the other hand, nutritionally rich, gluten free and stress tolerant plants like millets are neglected and underutilized. Millets sustain about one-third of the world’s population and show exceptional tolerance to various abiotic and biotic stresses. Millets are C4 plants that are adapted to marginal and dry lands of arid and semi-arid regions, and survive low rainfall… More >
