A key enzyme in inorganic nitrogen assimilation, glutamine synthetase, is the target of multiple regulatory mechanisms. Here we describe the nitrogen stress-induced RNA 4 (NsiR4), a small regulatory RNA that reduces the expression of inactivating factor 7 (IF7), an inhibitory factor of glutamine synthetase in cyanobacteria. The expression of NsiR4 is under positive control through the nitrogen control transcription factor (NtcA).

Phytophthora sojae is an oomycete pathogen that causes the disease known as root and stem rot in soybean plants, frequently leading to massive economic damage. Additionally, P. sojae is increasingly being utilized as a model for phytopathogenic oomycete research. Despite the economic and scientific importance of P. sojae, the mechanism by which it penetrates the host roots is not yet fully understood

Rice blast is one of the most devastating rice diseases and continuous resistance breeding is required to control the disease. The rice blast resistance gene Pi54 initially identified in an Indian cultivar confers broad-spectrum resistance in India. We explored the allelic diversity of the Pi54 gene among 885 Indian rice genotypes that were found resistant in our screening against field mixture of naturally existing M. oryzae strains as well as against five unique strains.

Modern plant breeding has made a profound impact on food production and will continue to play a vital role in world food security. For sustainable agriculture, a compromise should be sought between maximizing crop yield under changing climate and minimizing crop failure under unfavorable conditions. Such a compromise requires better understanding of the impacts of plant breeding on crop genetic diversity. Efforts have been made over the last three decades to assess crop genetic diversity using molecular marker technologies.

The objective of this study was to construct a single nucleotide polymorphism (SNP)-based genetic map at the cultivated tetraploid level to locate quantitative trait loci (QTL) contributing to economically important traits in potato (Solanum tuberosum L.). The 156 F1 progeny and parents of a cross (MSL603) between “Jacqueline Lee” and “MSG227-2” were genotyped using the Infinium 8303 Potato Array. Furthermore, the progeny and parents were evaluated for foliar late blight reaction to isolates of the US-8 genotype of Phytophthora infestans (Mont.) de Bary and vine maturity.

A total of 992,682 single-nucleotide polymorphisms (SNPs) was identified as ideal for Illumina Infinium II BeadChip design after sequencing a diverse set of 17 common bean (Phaseolus vulgaris L) varieties with the aid of next-generation sequencing technology. From these, two BeadChips each with >5000 SNPs were designed. The BARCBean6K_1 BeadChip was selected for the purpose of optimizing polymorphism among market classes and, when possible,

Because genetic variation underlies evolution, a complete understanding of evolutionary processes requires identifying and characterizing the forces determining the stability of the genome. Using mutation accumulation and whole-genome sequencing, we found that spontaneous mutation rates in three widely diverged Escherichia coli strains are nearly identical.

A long awn is one of the distinct morphological features of wild rice species. This organ is thought to aid in seed dispersal and prevent predation by animals. Most cultivated varieties of Oryza sativa and Oryza glaberrima, however, have lost the ability to form long awns. The causal genetic factors responsible for the loss of awn in these two rice species remain largely unknown.

Plant traits exhibit variation as a result of genetic and epigenetic change. Genetic variation is used for breeding and crop improvement. Epigenetic variation, especially differences in DNA methylation, also contributes to phenotype. For example, epigenetic alleles of plant genes exist in nature, which are identical in DNA sequence, but show heritable differences in DNA methylation and gene expression.

In pollen grains, the known function of the vegetative cell is to extend a pollen tube to transport the two sperm cells to the embryo sac for fertilization. Because the vegetative cell is much larger and more metabolically active than sperm, it has been assumed that the vegetative cell also might supply various components to sperm, but there was no direct evidence to support this hypothesis.
