Title

Functional Identification of ICE Transcription Factors in Rubber Tree

Yan Li; Caihong Quan; Shuguang Yang; et al. Forests 2022. doi:10.3390/f13010052

Other claims from this paper (14)

Observation Five ICE genes were isolated from rubber tree.
Observation The ICE genes shared a conserved domain region.
Observation The ICE factors localized to the nucleus.
Observation HbICE transcript abundance and expression patterns differed across cold and drought stress and clones.
Association HbICE expression was higher in cold-tolerant than cold-sensitive rubber tree clones.
Intervention effect HbICE1 overexpression enhanced cold tolerance in transgenic Arabidopsis and tobacco.
Intervention effect HbICE2 overexpression enhanced cold tolerance in transgenic Arabidopsis and tobacco.
Intervention effect HbICE4 overexpression enhanced cold tolerance in transgenic Arabidopsis and tobacco.
Intervention effect The transgenic plants had increased chlorophyll content under early cold stress.
Intervention effect The transgenic plants had decreased conductivity under early cold stress.
Intervention effect HbICE2 overexpression enhanced drought tolerance in Arabidopsis.
Intervention effect HbICE4 overexpression enhanced drought tolerance in Arabidopsis.
Intervention effect HbICE1 overexpression enhanced drought tolerance in Arabidopsis.
Mechanism Rubber tree cold tolerance is positively controlled by HbICE1, HbICE2 and HbICE4 expression.

Title

Response of Oryzacystatin I Transformed Tobacco Plants to Drought, Heat and Light Stress

K. Demirevska; L. Simova‐Stoilova; I. Fedina; et al. Journal of Agronomy and Crop Science 2009. doi:10.1111/j.1439-037x.2009.00396.x

Other claims from this paper (8)

Intervention effect Drought inhibited photosynthesis.
Intervention effect Drought decreased chlorophyll content.
Intervention effect Drought increased malondialdehyde and proline accumulation.
Intervention effect Heat alone did not significantly affect tobacco plants.
Intervention effect Heat intensified the effect of drought stress.
Intervention effect High light further increased proline content.
Intervention effect OC-I transformed tobacco had higher superoxide dismutase and guaiacol peroxidase activities and isoforms than controls in low light under stress and non-stress conditions.
Intervention effect OC-I expression did not highly affect catalase activity.
