DEAR4, a Member of DREB/CBF Family, Positively Regulates Leaf Senescence and Response to Multiple Stressors in Arabidopsis thaliana

Frontiers in Plant Science, 2020
Leaf senescence is a programmed developmental process regulated by various endogenous and exogenous factors. Here we report the characterization of the senescence-regulating role of DEAR4 (AT4G36900) from the DREB1/CBF (dehydration-responsive element ...

Studies on leaf senescence of super-highyield rice at flowing and grain formation stage

浙江大学学报. 农业与生命科学版, 2001
Flag leaf senescence of super-highyield rice—Peiai 64s/E32 and conventional rice Zhenong 952 after heading was studied with soil culture. The results indicate that photosynthetic rate decreased in the flag leaf after flowering.

Nitrogen deficiency regulates premature senescence by modulating flag leaf function, ROS homeostasis, and intercellular sugar concentration in rice during grain filling

Journal of Genetic Engineering and Biotechnology, 2021
Background Leaf senescence occurs in an age-dependent manner, but the rate and timing of leaf senescence may be influenced by various biotic and abiotic factors.

Uniconazole and nitrogen fertilization trigger photosynthesis and chlorophyll fluorescence, and delay leaf senescence in maize at a high population density

Photosynthetica, 2021
Reducing the leaf senescence rate could improve the grain yield in maize. In the present study, maize seeds were treated with uniconazole at concentrations of 0 and 25 mg kg-1, and nitrogen was applied at 0, 150, and 225 kg ha-1 to maize crop planted at ...

Overexpression of the maize transcription factor ZmVQ52 accelerates leaf senescence in Arabidopsis.

PLoS ONE, 2019
Leaf senescence plays an important role in the improvement of maize kernel yields. However, the underlying regulatory mechanisms of leaf senescence in maize are largely unknown.

Morphogenesis in pastures of Coastcross-1 and Tifton 85 mixed with forage peanut, submitted to cutting management

Semina: Ciências Agrárias, 2016
The objective of this study was to evaluate the effect of the presence of forage peanut (Arachis pintoi Krap. and Greg.) on the morphogenesis characteristics of two cultivars of Cynodon (Tifton 85 and Coastcross-1). The experimental design was factorial (

THE ROLES OF ASCORBIC ACID AND Α-TOCOPHEROL IN MINIMIZE OF SALT-INDUCED WHEAT FLAG LEAF SENESCENCE [PDF]

Journal of Plant Production, 2009
Experiments were conducted to study the α-tocopherol and ascorbic acid on modify the leaf senescence process of wheat grown under three salinity levels (0.8, 7.5, and 11.5 dSm-1). The parameters analyzed were soluble protein content, chlorophyll content,

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein

FEBS Letters, EarlyView.
Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.

De novo synthesis of short‐chain aldehydes and hydrocarbons secreted by the brown marmorated stink bug Halyomorpha halys

FEBS Open Bio, EarlyView.
The brown marmorated stink bug, Halyomorpha halys, mainly secretes 4‐oxo‐(E)‐2‐hexenal, (E)‐2‐decenal, dodecane and tridecane, a mixture representative of that released by many heteropterans. We demonstrated that H. halys can synthesise these secretory components de novo using dietary glucose.

Characterization of photosynthetic performance during senescence in stay-green and quick-leaf-senescence Zea mays L. inbred lines. [PDF]

PLoS ONE, 2012
The net photosynthetic rate, chlorophyll content, chlorophyll fluorescence and 820 nm transmission were investigated to explore the behavior of the photosynthetic apparatus, including light absorption, energy transformation and the photoactivities of ...
