Project description:The plant hormone jasmonic acid (JA) has been known as a signal molecule that is induced by various stresses and mediates plant defense responses. Rice O. sativa inductively produces variety of defensive compounds upon abiotic and biotic stress conditions, such as wounding and insect attack. We identified wound-inducible genes by comparison with transcriptomes between wounded and untreated wild-type rice leaves. Expression profiling in wild-type rice leaves treated by wounding for 0.5, 1, 2 and 4 h was compared with that in untreated control using two-color method with two biological replicates.

Rice bHLH transcription factor RERJ1 dependent wound inducible genes in rice leaves

Project description:The plant hormone jasmonic acid (JA) has been known as a signal molecule that is induced by various stresses and mediates plant defense responses. Rice O. sativa inductively produces variety of defensive compounds upon abiotic and biotic stress conditions, such as wounding and insect attack. The bHLH transcription factor RERJ1 has previously been identified as JA-inducible factor whose expression is also rapidly induced by wounding. We identified RERJ1-dependent and wound-inducible genes by comparison with transcriptomes of wound treated wild-type and a Tos17-rerj1 defective mutant rice. Expression profiling between rice leaves of wild-type and tos17-rerj1 mutant treated by wounding for 0, 0.5, 1 and 2 h was compared using two-color method with two biological replicates.

Wound response of LapA-silenced tomato leaves

Project description:LapA encodes an acidic leucine aminopeptidase that is wound-inducible and found only in tomato (Solanum lycopersicum) and a small subset of the Solanaceae. LapA is expressed in developing flowers, fruit and in foliage after wounding, insect feeding (Manduca sexta), Pseudomonas syringae pv. tomato infection, salinity, and water-deficit stress. Using Agrobacterium tumefaciens, UC82b plants were transformed with a chimeric gene containing the CaMV 35S promoter and LapA cDNA in the sense orientation. Kanamycin-resistant plants were screened by RNA and protein blots to identify plants that did not accumulate and LAP-A protein upon wounding; these plants were designated LapA-silenced (LapA-SI) lines. The LapA-SI plants have an impaired wound response and do not accumulate wound response transcripts (proteinase inhibitors and polyphenol oxidase) to wild-type levels. LAP-A is the first aminopeptidase to be shown to have a regulatory role in plants. LapA-SI and UC82b plants were germinated on filter paper for 7 days before being planted in soil. Plants were grown in a growth chamber, (16 hour days at 28°C, 8 hour nights at 24°C, 50% humidity) for three weeks. Plants were wounded by crushing each leaflet on each of two lower leaves with pliers. Wounded leaves were collected at 0, 1 and 8 hr (local wounded tissue). Two upper, unwounded leaves were collected from the same plants at the same times (systemically wounded tissue). Five to seven plants were pooled for each time point. The experiment was repeated three times. RNA was extracted using a hot phenol/LiCl protocol and purified and DNase treated using the SV Total RNA Isolation Kit from Promega.

Transcriptome of Xanthoceras sorbifolia Bunge leaves under low nitrogen condition

Project description:Transcriptome sequencing (RNA-seq) was used to sequence the leaves of Xanthoceras sorbifolia Bunge under low nitrogen, so as to analyze the resistance of Xanthoceras sorbifolia Bunge to low nitrogen.
