Temperatures that extend beyond normal levels of tolerance cause severe stress to plants, especially during the reproductive and grain filling/ripening stages. Heat stress leads to serious yield losses in many crop plants, including rice (

Gibberellins (GAs) are important hormones at every plant developmental stage including vegetative and reproductive. It is reported in many plant species that many dwarfism and male sterile mutants have defective GA biosynthesis genes. RNA interference (RNAi) technology can reduce expression of specific genes at the transcription level. Also, promoters can control the spatial and temporal expression of genes. Specific promoters containing the RNAi vector can control specific genes’ spatial and temporal expression at the transcriptional level. In this study, at first, five anther specific promoters were chosen and verified by examining their tissue specific expression using promoter::GUS transgenic analysis. RNAi vectors, which contain five anther specific promoters and one constitutive promoter fused to GA biosynthesis related genes, were constructed for controlling of GA biosynthesis in stem and floral tissue.

The faba bean produces medicinally useful phenolic compounds naturally, and is also a good source of food and animal feed. This study quantified the functional compounds and antioxidant activities of five faba bean genotypes selected on the basis of their seed yield and L-dopa content. The highest total tannin content (TTC) and total proanthocyanidin content (TPAC) were observed in the PI252004 genotype and the lowest content in the PI366039 genotype. The total phenolics content (TPC) and total flavonoid content (TFC) of the PI430715 genotype were higher than those of the other genotypes. LC-MS analyses identified 22 different phenolic compounds in the faba bean genotypes. The most abundant proanthocyanidin compounds were prodelphinidin and catechin and the predominant flavonols and flavones were myricetin, quercetin, apigenin, kaempferol, and luteolin-free aglycones or glycosides. The TFC was correlated with ferric-reducing antioxidant power activity (FRAP) (

Repetitive DNA elements are ubiquitous in plant genomes. Although repeats provide relevant information for cytogenetic, evolutionary, and genomic studies, identifying and characterizing their sequence and chromosomal distribution are not always easily achieved through conventional methods. However, a high-throughput identification of genomic repeats can be obtained with short reads from next-generation sequencing data. Here, we identified the telomeric and two chromosome-specific repeats in

Plants adapt to hostile environmental condition through specialized cellular processes which require coordinated regulation of multiple transport mechanisms. Low-affinity cation transporter (LCT) 1 is a membrane transporter gene exclusive only to members of the grass family, and the rice genome contained only one copy of the gene. Accumulating evidence highlighted the important role of this gene in the regulation of various cations transport into the plant cells including heavy metals. To further characterize the role of this membrane transporter
