Project description:Alkaline soils such as those found in some Mediterranean areas typically have a low phosphorus (P) and zinc (Zn) phytoavailability that detracts from plant growth and yield. We examined the effects of P and Zn fertilization individually and in combination on growth, yield and grain protein content in maize grown in pots filled with three Mediterranean soils. P and Zn translocation was impaired, and yield reduced by 8–85%, in plants treated with Zn or P alone. In contrast, joint fertilization with P and Zn enhanced translocation to grain and nutrient use efficiency, thereby increasing plant growth, yield (31–121%) and grain Zn availability. Fertilization with P or Zn also influenced the abundance of specific proteins affecting grain quality (viz., storage, lys-rich and cell wall proteins), which were more abundant in mature grains from plants fertilized with Zn alone and, to a lesser extent, P + Zn.
Project description:Purpose: transcriptome sequencing of Conopomorpha sinensis Methods: high-through Illumina HiSeqTM 2000 Results:66017 transcripts,35383 unigenes Conclusions:This study provided valuable transcriptome data for the litchi fruit borer, which was the first fundamental genomic basis for exploiting gene resources from the litchi fruit borer
Project description:In synchrony with deciphering the transcriptomic basis of pod borer resistance in C. platycarpus, the aim of the present work was to corroborate and understand how the leaf proteome in these two contrasting cajanus species explain the differential responses to herbivory. To the best of our knowledge this is the first investigative analysis applying proteomics to understand plant herbivore interactions in cajanus species. The study is one of the best approaches to assess cellular alterations from a multi-level perception and to enhance our understanding of resistance traits in the wild relatives.
Project description:Stalk borers are major pests for some of the most important crops in the world, such as maize or rice. Plant defense mechanisms against these herbivores have been poorly investigated. The maize´s stalk responds to insect feeding activating defense genes including hormone biosynthetic-related or proteinase inhibitor transcripts. The most outstanding conclusion is that cells in the maize´s stalk undergo cell wall fortification after corn borer tunneling. We performed a gene expression profiling to identify those genes differentially expressed in maize after infestation with the corn borer S. nonagrioides.
