Transcriptomic and metabolomic analysis reveal that fullerol improves drought tolerance in Brassica napus L.

ABSTRACT: The fullerenes, a kind of carbon nanoparticles, have potential for enhanced stress tolerance in plants. While the positive effects of polyhydroxy fullerene—fullerol on plants in response to drought at the physiological level have been documented, the molecular mechanism in Brassica napus are not entirely understood. In this study, exogenous fullerol was applied to the leaves of B. napus seedlings given drought. The leaves of B. napus seedlings in each treatment (sufficient water condition, drought, and drought combined with fullerol) were used to conduct the molecular mechanism using transcriptomic analysis.

RNAseq of Brassica napus seed

Project description:mRNA expression profiling of the embryo, endosperm (micropylar, peripheral, chalazal), and seed coat (outer, inner, chalazal, chalazal proliferating tissue) of the developing Brassica napus seed. Tissues were isolated using laser microdissection (LMD) from Brassica napus seeds at the globular, heart, and mature green stages of seed development.

Brassica napus control vs. heat stress

Project description:High temperature stress results in yield loss and alterations to seed composition during seed filling in oilseed rape (Brassica napus). However, the mechanism underlying this heat response is poorly understood. In this study, we employed a microarray analysis with silique walls and seeds from the developing siliques (20 days after flowering) of Brassica napus that had undergone heat stress.

Comparative proteomics analysis of Brassica napus in response to drought stress

Project description:Drought is one of the most severe stresses leading to retardation of plant growth and development and loss of crop yield. Here we examined the proteome changes of an important oil seed crop canola Brassica napus under drought stress over a 14 day period. Using iTRAQ LC-MS/MS, we identified 2,244 proteins expressed during drought stress. Among them, 412 proteins showed significant changes in abundance under stress, and 67, 243, 287, and 79 proteins were differentially expressed in 3rd, 7th, 10th, and 14th day of drought stress, respectively. Functional analysis of the 412 proteins indicated that the number of proteins associated with “Metabolism”, “Protein synthesis”, and “Signaling” decreased, while those related to “Photosynthesis” and “Stress and defense” increased in response to drought stress. In particular, the proteome profiles at the 7th and 10th day were similar to each other, although there were much more post-translational modifications (PTM) at the 10th day of drought. Interestingly, 286 of 2,244 proteins exhibited PTMs in response to drought stress, 82 of which were differentially changed in drought-stressed plants, and 60 were observed at the 10th day. Furthermore, comparison of protein expression changes with those of gene transcription showed that there was positive correlation in B. napus, although there were different patterns between transcripts and proteins at each time point. As drought stress prolongs, most of the protein abundance changes may be attributed to gene transcription, and PTMs clearly contribute to the protein diversity and functions.

Activation of plant defence in Brassica napus L. cv. Westar and transgenic MINELESS plants after attack by Mamestra brassicae (cabbage moth)

Project description:Plants within the Brassicaceae family have a unique defence mechanism known as the “glucosinolate-myrosinase” system. Upon tissue disruption by insect herbivores, glucosinolates are hydrolysed by the enzyme myrosinase (EC 3.2.1.147) into a variety of degradation products, which can deter insect herbivory. This process has been termed as “The Mustard Oil Bomb”. Seeds of Brassica napus have been genetically modified to remove myrosinase containing myrosin cells. The modified plants have been named MINELESS due to a lack of toxic mines in seeds. This study aimed to get insights into defence responses of B. napus wild-type and MINELESS seedlings, after being challenged by larvae of the generalist herbivore Mamestra brassicae. The microarray analysis showed 494 and 159 genes to be differentially regulated after M. brassicae feeding on wild-type and MINELESS seedlings, respectively. Many of the observed transcriptional responses i B. napus and the MINELESS mutant are related to those found in Arabidopsis thaliana plants when they are exposed to insects.

The molecular response of two Brassica napus cultivars to submergence

Project description:Heavy rainfall causes flooding of natural ecosystems as well as farmland, negatively affecting crop performance and yield. While the response of the wild model organism Arabidopsis thaliana to such stress conditions is well understood, we hardly know anything about the response of its relative, the important oil crop plant Brassica napus. Here, we analyzed the molecular response of leaves of rapeseed seedlings to full submergence under illumination. RNAseq experiments revealed a strong carbon starvation response under submergence, but no indication for a low-oxygen response. We used two cultivars in this study, one Asian flooding-tolerant cultivar and one European hybrid cultivar, but those genotypes did not show strong differences in their responses to submergence.

Gene expression profilling of six species of Brassica and early four generation of resynthesized B. napus (F1-F4)

Project description:Analysis of the different gene expression profiles of natural and resynthesized Brassica polyploids with Illumina deep sequencing technology could help to improve our knowledge of polyploid genome evolution. We obtained approximately 6 million sequence tags per sample,and 6018254, 5930726, 6022170, 5950123, 5991210, 5798939, 5823113, 5772449,5858527 and 5657697 clean tags were obtained in libraries of B. rapa, B. oleracea, B. napus-F1, B. napus-F2, B. napus-F3, B. napus-F4, natural B. napus, B. nigra, B. juncea and B. carinata, respectively.16574, 15970, 22059, 18155, 16479, 18196, 17448, 13867, 19424 and 16645 genes of B. rapa genome were unambigously mapped by sequence tags of these ten DGE libraries, respectively. Differentially expressed genes during polyploidization were broadly discovered by comparing the tetraploids with their progenitors. mRNA obtained from young leaves of 28-days-old seedlings were compared during polyploidization.
