Stress-Induced Flowering in Pharbitis—A Review
Many plant species are induced to flower by stress. Stress-induced flowering has been studied mostly in the short-day plant pharbitis (also called Japanese morning glory; Ipomoea nil, formerly Pharbitis nil). In this article, physiological characteristics, the regulation by salicylic acid (SA) and the expression of flowering-related genes in stress-induced flowering in pharbitis are reviewed. P...
متن کاملEnvironmental stress and flowering time
After the f loral transition the shoot apical meristem (SAM) changes its identity switching from vegetative to reproductive. In annual Arabidopsis ecotypes, the transition to f lowering is strongly promoted by variations in day length (photoperiod). The photoperiodic pathway promotes f lowering when Arabidopsis plants are exposed to long days (LDs) conditions (typical of spring and summer). Pho...
متن کاملEnvironmental stress influencing plant development and flowering.
Plants are sessile organisms and unlike animals, cannot run away from adverse environmental conditions. Therefore, they have evolved sophisticated signaling and protective systems to overcome sub-lethal stress situations. Although, effect of stress on physiology and morphology were studied earlier, the research on molecular mechanisms of stress response is albeit new. Studies at the molecular l...
متن کاملStress-induced early flowering is mediated by miR169 in Arabidopsis thaliana.
Plants interact with their environment and they often flower earlier under stress conditions, but how such stress-induced flowering is regulated remains poorly understood. Here evidence is presented that the miR169 family plays a key role in stress-induced flowering in plants. The microRNA (miRNA) miR169 family members are up-regulated in Arabidopsis, maize, and soybean under abiotic stresses. ...
متن کاملIs early morning flowering an effective trait to minimize heat stress damage during flowering in rice?
Higher spikelet sterility due to heat stress exposure during flowering in rice is becoming a major threat for sustaining productivity in tropical and sub-tropical regions. Therefore, exploiting and incorporating early morning flowering (EMF) trait into ongoing breeding pipelines could be an effective strategy to minimize the damage. In this study, we have focused on quantifying the time of day ...
