In maize, the Rp3 gene confers resistance to common rust caused by Puccinia sorghi. Flanking marker analysis of rust-susceptible rp3 variants suggested that most of them arose via unequal crossing over, indicating that rp3 is a complex locus like rp1. The PIC13 probe identifies a nucleotide binding site-leucine-rich repeat (NBS-LRR) gene family that maps to the complex. Rp3 variants show losses...

Tebu (Saccharum officinarum) merupakan tanaman perkebunan penting sebagai penghasil utama gula di Indonesia. Penurunan produksi tebu dalam beberapa tahun terakhir tidak sejalan dengan permintaan yang kian meningkat. Pemuliaan diarahkan untuk mendapatkan varietas-varietas unggul diharapkan memiliki produktivitas tinggi dan tahan terhadap faktor-faktor gangguan dapat menurunkan tanaman. Pengamata...

Botanical pesticides have gradually become accepted for use in the control of agricultural pests. In order to clarify active compounds ginger (Zingiber officinale) shoot extract (GSE) and its inhibitory effect on growth sorghum aphids (Melanaphis sorghi). this study, LC-MS/MS was used determine major GSE, leaf disc method explore insecticidal response mechanism aphids. The results showed that p...

To understand the molecular basis of sugarcane-smut interaction, it is important to identify sugarcane genes that respond to the pathogen attack. High-throughput tag-sequencing (tag-seq) analysis by Solexa technology was performed on sugarcane infected with Sporisorium scitaminea, which should have massively increased the amount of data available for transcriptome profile analysis. After mappin...

Sporisorium reilianum has caused significant economical damages in Mexico, in temperate and relatively dry areas, where maize is cultivated. The knowledge about the spatial distribution of this pathogen is basic to elaborate integrated management programs, and precise and eff icient the development of sampling methods and control techniques. Unfortunately, in Mexico there are no studies on spat...
