Heading date; miRNA; Prediction model; Real-time PCR; Rice

Rice (Oryza sativa L.) is one of the most important food crops in the world. In Taiwan, due to the warm climate, there are two harvests annually. However, the yield and quality of rice can vary between each crop season in any given year. Previous reports have shown that microRNAs (miRNAs) play a crucial role in many developmental and physiological processes in plants. In this ... more

Quantitative trait loci; Rice; Seed-shattering genes; Sequence characterized amplified region marker; Simple sequence repeat

Seed shattering of wild plant species is thought to be an adaptive trait to facilitate seed dispersal. For rice breeding, seed shatter­ing is an important trait for improving breeding strategies, particularly when developing lines use interspecific hybrids and introgression of genes from wild species. We developed F3:4 recombinant inbred lines from an interspecific cross ... more

Abiotic stress; Aluminum; Gene expression; MicroRNAs

MicroRNAs are small 21-nucleotide RNA molecules with regulatory roles in development and in response to stress. Expression of some plant miRNAs has been specifically associated with responses to abiotic stresses caused by cold, light, iron, and copper ions. In acid soils, aluminum solubility increases, thereby causing severe damage to plants. Although physiological aspects of aluminum ... more

Abiotic stress; Drought stress; Sorghum bicolor; Sorghum breeding; Sorghum yield

Twenty-five cultivars of grain sorghum [Sorghum bicolor (L.) Moench] were examined under both drought stress and normal conditions in 4 experiments. In each condition, genotypes were evaluated in a factorial experiment using a randomized complete block design with 3 replications. Eight drought tolerance indices including stability tolerance index, mean productivity (MP), ... more

Abiotic stress; Genetic engineering; GmIMT1gene; Soybean

Here, we aimed to clone and identify the GmIMT1 gene related to the salt stress response in soybean. The full-length cDNA sequence of the GmIMT1 gene was amplified in soybean using degenerate primers of Mesembrythmum crystallium. To understand the stress response, the GmIMT1 gene was cloned and sequenced. Then, the expression vectors of the gene were ... more

Biochemical mechanisms; Biotic stress; Pathogenesis-related proteins; Resistance to diseases

Pathogenesis-related proteins (PRs) are among the defense mechanisms of plants that work as an important barrier to the development of pathogens. These proteins are classified into 17 families according to their amino acid sequences, serology, and/or biological or enzyme activity. The present study aimed to identify PRs associated with the pathosystem of Capsicum baccatum var. ... more

Biotic stress; Chorismate mutase 2; Cytosolic; Sugarcane

Xanthomonas albilineans causes leaf scald disease, one of the most economically important diseases of sugarcane. Leaf scald is a systemic and vascular disease that can severely reduce productivity. The best and primary method of leaf scald control is the use of tolerant cultivars. Knowing that cell wall lignification is a plant defense ... more
