RNA-seq reveals the downregulated proteins related to photosynthesis in growth-inhibited rice seedlings induced by low-energy N+ beam implantation

Q. F. Chen, Ya, H. Y., Wang, W. D., and Jiao, Z., “RNA-seq reveals the downregulated proteins related to photosynthesis in growth-inhibited rice seedlings induced by low-energy N+ beam implantation”, vol. 13, pp. 7029-7036, 2014.

Transcriptomic research based on RNA sequencing (RNA-seq) technology is innovative and will provide new opportunities and biological perspectives for the use of ion-beam implantation in plants. Using RNA-seq, transcriptomes of whole rice seedlings generated from seeds implanted with a low-energy N+ beam were analyzed 96 h after planting. We identified 544 transcripts that were differentially expressed genes (DEGs) in the non-growth-inhibited sample implanted by an N+ beam, including 262 upregulated transcripts and 282 downregulated transcripts.

Changes in protein profile detected in seedlings of Caesalpinia peltophoroides (Fabaceae) after exposure to high concentration of cadmium

L. M. C. Gomes, Gesteira, A. S., de Almeida, A. - A. F., de Castro, A. V., Dias, L. O., Pirovani, C. P., and Gomes, F. P., “Changes in protein profile detected in seedlings of Caesalpinia peltophoroides (Fabaceae) after exposure to high concentration of cadmium”, vol. 11, pp. 2694-2707, 2012.

Sibipiruna (Caesalpinia peltophoroides Benth) is a tree of the Brazilian Atlantic Forest. It is a flowering ornamental tree widely planted throughout Brazil and indicated for restoration of degraded areas. We examined protein profile changes in leaves of seedlings of C. peltophoroides grown in nutrient solution under greenhouse conditions, after exposure to cadmium (Cd; 32 mg/L). A two-dimensional gel was used to analyze proteins expressed in response to stress 24 and 72 h after initiation of treatment with Cd.
