Starch is one of the most important quality characteristics of potatoes, which is widely used in the food, medical, petrochemical and other industries. The demand for starchy potato varieties in the market is increasing year by year. To explore the characteristics and key genes of starch accumulation and regulation of potato tuber, in this study, transcriptome profiling of creeping stems (a), pre-tuber expansion (b), mid-tuber expansion (c), late tuber expansion (d), and mature stage (e) of high and low starch potato cultivars DXY and DS1 were conducted by RNA sequencing analysis, and a total of 9494 differentially expressed genes (DEGs) were identified at five stages. Binding function annotation revealed that the differential genes were mainly enriched in molecular functions such as binding and catalytic activity. Metabolic pathway analysis revealed that the differential genes were mainly enriched in carbohydrate-related metabolic pathways, and 137 DEGs were associated with starch and sucrose metabolism. Nine key genes regulating starch synthesis were examined, and the relative expression level of the sucrose synthase gene PGSC0003DMG400013547 was higher during growth period of DXY than that at any stage. The relative expression level of the fructokinase gene PGSC0003DMG400026916 was significantly higher in DXY than in DS1 during the a and b periods. The relative expression level of amylase gene PGSC0003DMG400009891, PGSC0003DMG400001549, and glucan endo-1,3-β-glucosidase gene PGSC0003DMG400024642, PGSC0003DMG400003181 in DS1 was significantly higher than that in DXY with in DXY with starch-rich cultivars during the c and e periods. The described gene might be a key regulatory gene for starch synthesis and accumulation. This study provides a clue for the investigation of the regulatory mechanism of tuber starch metabolism in different potato cultivars. [ABSTRACT FROM AUTHOR]

The increasing problem of soil salinization has seriously threatened global agricultural development. Rapeseed (Brassica napus) is an important oil crop. At present, a series of progress has been achieved in QTL research on salt tolerance related traits of rapeseed. In this article, progress on damage and mitigation mechanism of salt stress to rapeseed growth were reviewed, effects of salt stress on rapeseed at different development stages was reviewed, and QTL researches on salt-tolerant related traits were summarized. Also, breeding achievement of salt-tolerant rapeseed varieties in China was prospected. It was expected to provide reference for further research on salt tolerance mechanism in rapeseed and breeding new salt-tolerant varieties. [ABSTRACT FROM AUTHOR]

To ascertain the influence of temperature on development, fecundity and population of Atractomorphasinensis (I.Bolivar) in field, duration of different developmental stages of the insect were compared in laboratory under constant temperature of 16°, 20°, 24°, 28° and 32°, with photoperiod of 16L:8D at RH 70%. With soybean leaves as food, duration, developmental rate of each life stage and reproduction were systematically observed. Developmental threshold temperature and effective accumulated temperature were further calculated. Population trends under different experimental temperatures were also analyzed by life table technology. Results showed that developmental period of each stage of A. sinensis were decreased from 16 to 32°, and a significant positive correlation between developmental rate and temperature was confirmed by fitting equation. Developmental threshold temperatures of egg, nymph and adult were 9.58, 10.55 and 11.40° respectively. Effective accumulated temperature were 449.80, 540.03 and 430.94 degree-days respectively. Insect fecundity was the highest at 28°, with average 66.12 eggs laid per female, followed by 60.30 eggs laid per female at 24° and the lowest was 28 eggs at 16°. Experimental population trend index was less than 1 under each test temperature, and the maximum was at 24°, which was 18.97. These results were expected to provide a scientific basis for field prediction and integrated management of A. sinensis (I.Bolivar). [ABSTRACT FROM AUTHOR]
