Background: Understanding late pollen development, including the maturation and pollination process, is a key component in maintaining crop yields. Transcriptome data obtained through microarray or RNA-seq technologies can provide useful insight into those developmental processes. Six series of microarray data from a public transcriptome database,...

This paper investigates the effects of vertical integration on screening decisions using data from the Korean movie industry. We find that integrated theaters show their affiliated movies more than nonaffiliated movies, and more than nonintegrated theaters do. However, this gap reduces during the peak times of the day and after the opening week. Ou...

Bacterial leaf blight (BLB) caused by Xanthomonas oryzae pv. oryzae (Xoo) is one of the most serious threats to rice production. In this study, screening of rice for resistance to BLB was carried out at two different times and locations, i.e., in a greenhouse during winter and in an open field during summer. Pathogenicity of Xoo race K1 tested on 3...

This study was carried out to evaluate the expression of yellow endosperm color in the progeny of Psy-2A-CrtI (β-carotene gene, PAC) transgenic plants crossed with IR36. The selected 25 lines of F2 progeny exhibited stable expression of yellow endosperm color and high agronomic characteristics. IR36 and PAC transgenic plant of the grain length, wid...

Rice is the second most important cereal after maize in Ghana. Rice consumption has been growing rapidly, mainly around towns such as Accra. However, self-sufficiency rate remains to be about 46% of the national consumption. Ghana depends largely on imported rice to augment the domestic deficit in rice supply. High level of dependence on imported r...

During rice cultivation, brown planthopper (BPH, Nilaparvata lugens Stal.) and white-backed planthopper (WBPH, Sogatella furcifera) infestations cause decreased yield and rice quality. In this study, we attempted to develop multi-resistance plants and increase the marker-assisted selection (MAS) efficiency. The frequency of callus induction in 95 F...

This study examined the antioxidant activity of the dark purple rice seeds from the rice line, MGI079, derived from insertional mutagenesis. The contents of polyphenolic compounds were 1.3 and 1.9-fold higher in the MGI079-2-1 and MGI079-2-6 rice lines than in the donor cultivar MGI079. Flavonoid contents were 6.4-fold higher in the MGI079-2-1 line...
