Project description:Cultivated soybean has domesticated in China for a long history, and there are several significant phenotypic differences between wild and cultivated soybeans. Seed of cultivar is generally larger than wild soybean, therefore here we comprehensively analyzed transcriptomes of thirteen soybean accessions seeds including seven wild soybeans and six landraces through applying strand-specific RNA sequencing. Differential expressed genes related seed weight were identified, some of them were known to be associated with seed development in Arabidopsis. Noncoding RNAs are known to play important roles in plant development, and we profiled the expression pattern of long noncoding RNA (lncRNA) in cultivated and wild soybean seeds. We have identified 1,251 long intergenic noncoding RNA, 243 intronic RNA and 81 antisense lncRNA, transcriptional levels of a number of lncRNAs were significantly different between cultivated and wild soybeans, suggesting that lncRNA may be involved in soybean seed development.
Project description:We present metaproteome data from maize rhizosphere from sodic soil. Isolation of proteome from maize rhizosphere collected from Experimental Farm, ICAR-IISS, Mau, India was done with the standardized protocol at our laboratory and metaproteome analysis was done with the standardized pipepline. In total 696 proteins with different functions representing 245 genus and 395 species were identified. The proteome data provides direct evidence on the biological processes in soil ecosystem and is the first reported reference data from maize rhizosphere.
Project description:We report total mRNA library using Illumina Nova Seq high-throughput sequencing platform platform for analysis of transcriptome between the two relatives of the soybean ie weedy and cultivar growth types in F7 generation derived from the crossing of wild and cultivated soybean.
Project description:Interspecies interactions play a key role in soil-borne disease suppression in intercropping systems. However, there are limited data on the underlying mechanisms of soil-borne Phytophthora disease suppression. Here, a field experiment confirmed the effects of maize and soybean intercropping on Phytophthora blight of soybean caused by Phytophthora sojae. Experimentally, the roots and root exudates of maize were found to attract P. sojae zoospores and inhibit their motility and the germination of cystospores. Furthermore, five phenolic acids (p-coumaric acid, cinnamic acid, p-hydroxybenzoic acid, vanillic acid, and ferulic acid) that were consistently identified in the root exudates and rhizosphere soil of maize were found to interfere with the infection behavior of P. sojae. Among them, cinnamic acid was associated with significant chemotaxis in zoospores, and p-coumaric acid and cinnamic acid showed strong antimicrobial activity against P. sojae. However, in the rhizosphere soil of soybean, only p-hydroxybenzoic acid, low concentrations of vanillic acid, and ferulic acid were identified. Importantly, the coexistence of five phenolic acids in the maize rhizosphere compared with three phenolic acids in the soybean rhizosphere showed strong synergistic antimicrobial activity against the infection behavior of P. sojae. In summary, the types and concentrations of phenolic acids in maize and soybean rhizosphere soils were found to be crucial factors for Phytophthora disease suppression in this intercropping system.
