Regulation of carotenoid metabolism and ABA biosynthesis during blueberry fruit ripening.

Carotenoids and their derivates play critical physiologic roles in plants. However, these substrates and their metabolism have not been elucidated in fruit of blueberry (Vaccinium corymbosum). In this study, carotenoids and ABA were investigated by LC-MS and their biosynthesis were subject to proteomic analysis during fruit ripening.

PIF1, a phytochrome-interacting factor negatively regulates drought tolerance and carotenoids biosynthesis in tobacco.

The phytochrome-interacting factors (PIFs) function crucially in multiple physiological processes, but the biological functions of some PIFs remain elusive in some species. Here, a PIF transcription factor NtPIF1 was cloned and characterized in tobacco (Nicotiana tabacum L.).

Construction of an alanine dehydrogenase gene deletion strain for vaccine development against Nocardia seriolae in hybrid snakehead (Channa maculata ♀ × Channa argus ♂).

Nocardia seriolae is the main pathogen of fish nocardiosis. In our previous study, alanine dehydrogenase was identified as a potential virulence factor of N. seriolae.

Quantitative trait loci associated with straighthead-resistance used for marker assisted selection in rice ( L.) RIL populations.

Straighthead is a physiological disorder of rice ( L.) that causes dramatic yield loss in susceptible cultivars. This disorder is found worldwide and is reported to increasingly occur in the southern United States.

Naringenin confers defence against Phytophthora nicotianae through antimicrobial activity and induction of pathogen resistance in tobacco.

Tobacco black shank caused by Phytophthora nicotianae is a serious disease in tobacco cultivation. We found that naringenin is a key factor that causes different sensitivity to P. nicotianae between resistant and susceptible tobacco.

Identification of QTLs Associated With Agronomic Traits in Tobacco a Biparental Population and an Eight-Way MAGIC Population.

Agronomic traits such as plant height (PH), leaf number (LN), leaf length (LL), and leaf width (LW), which are closely related to yield and quality, are important in tobacco ( L.). To identify quantitative trait loci (QTLs) associated with agronomic traits in tobacco, 209 recombinant inbred lines (RILs) and 537 multiparent advanced generation intercross (MAGIC) lines were developed.

Bioinformatics study of 1-deoxy-D-xylulose-5-phosphate synthase (DXS) genes in Solanaceae.

Isoprenoids, the largest and most diverse class of secondary metabolites in plants, play an important role in plant growth and development. Isoprenoids can be synthesized by two distinct pathways: the methylerythritol-4-phosphate (MEP) pathway and the mevalonate (MVA) pathway. 1-Deoxy-D-xylulose-5-phosphate synthase (DXS) is the first step and a key regulatory enzyme of the MEP pathway in plants.

Proteins expression and metabolite profile insight into phenolic biosynthesis during highbush blueberry fruit maturation.

Blueberry is one of the richest phenolic sources, providing health benefits. To study blueberry phenolic biosynthesis, we investigated phenolics and proteomics at three typical fruit maturation phases. Multiple isoforms of enzymes and multiple members of transcription factors involved in phenolic biosynthesis were divergent and differently regulated.

NtMYB4 and NtCHS1 Are Critical Factors in the Regulation of Flavonoid Biosynthesis and Are Involved in Salinity Responsiveness.

High levels of salinity induce serious oxidative damage in plants. Flavonoids, as antioxidants, have important roles in reactive oxygen species (ROS) scavenging. In the present study, the tobacco R2R3 MYB type repressor, NtMYB4, was isolated and characterized.

Association Analysis of Arsenic-Induced Straighthead in Rice ( L.) Based on the Selected Population with a Modified Model.

A rice physiological disorder makes mature panicle keep erect with empty grains termed as "straighthead." Straighthead causes yield losses and is a serious threat to rice production worldwide. Here, a new study of association mapping was conducted to identify QTL involved in straighthead.

Development of genetic markers linked to straighthead resistance through fine mapping in rice (Oryza sativa L.).

Straighthead, a physiological disorder characterized by sterile florets and distorted spikelets, causes significant yield losses in rice, and occurs in many countries. The current control method of draining paddies early in the season stresses plants, is costly, and wastes water. Development of resistant cultivar is regarded as the most efficient way for its control.
