A Role for Diacylglycerol Acyltransferase during Leaf SenescenceOxford University Press (OUP) - Tập 129 Số 4 - Trang 1616-1626 - 2002

Abstract
Lipid analysis of rosette leaves from Arabidopsis has revealed an accumulation of triacylglycerol (TAG) with advancing leaf senescence coincident with an increase in the abundance and size of plastoglobuli. The terminal step in the biosynthesis of TAG in Arabidopsis is catalyzed by diacylglycerol acyltransferase 1 (DGAT1; EC 2.3.1.20). When ...... hiện toàn bộ
The MYB96 Transcription Factor Mediates Abscisic Acid Signaling during Drought Stress Response in ArabidopsisOxford University Press (OUP) - Tập 151 Số 1 - Trang 275-289 - 2009

AbstractPlant adaptive responses to drought are coordinated by adjusting growth and developmental processes as well as molecular and cellular activities. The root system is the primary site that perceives drought stress signals, and its development is profoundly affected by soil water content. Various growth hormones, particularly abscisic acid (ABA) and auxin, pla...... hiện toàn bộ
Cotyledon-Generated Auxin Is Required for Shade-Induced Hypocotyl Growth in Brassica rapa Oxford University Press (OUP) - Tập 165 Số 3 - Trang 1285-1301 - 2014

Abstract
Plant architecture is optimized for the local light environment. In response to foliar shade or neighbor proximity (low red to far-red light), some plant species exhibit shade-avoiding phenotypes, including increased stem and hypocotyl growth, which increases the likelihood of outgrowing competitor plants. If shade persists, early flowering ...... hiện toàn bộ
Ubiquitin-Specific Proteases UBP12 and UBP13 Act in Circadian Clock and Photoperiodic Flowering Regulation in Arabidopsis Oxford University Press (OUP) - Tập 162 Số 2 - Trang 897-906 - 2013

Abstract
Protein ubiquitination is involved in most cellular processes. In Arabidopsis (Arabidopsis thaliana), ubiquitin-mediated protein degradation regulates the stability of key components of the circadian clock feedback loops and the photoperiodic flowering pathway. Here, we identified two ubiquitin-specific proteases, UBP12 and UBP13, involved i...... hiện toàn bộ
Ethylene and Auxin Control the Arabidopsis Response to Decreased Light IntensityOxford University Press (OUP) - Tập 133 Số 2 - Trang 517-527 - 2003

AbstractMorphological responses of plants to shading have long been studied as a function of light quality, in particular the ratio of red to far red light that affects phytochrome activity. However, changes in light quantity are also expected to be important for the shading response because plants have to adapt to the reduction in overall energy input. Here, we pr...... hiện toàn bộ
