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

open access: yesPhotosynthetica, 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 ...

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

open access: yesJournal 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.

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

open access: yesPLoS 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.

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

open access: yesJournal 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,

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

open access: yesSemina: 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 (

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

open access: yesMolecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

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

open access: yesPLoS 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 ...

Complementarity of Long‐Reads and Optical Mapping in Parkinson's Disease for Structural Variants

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Long‐read sequencing and optical genome mapping technologies have the ability to detect large and complex structural variants. This has led to the discovery of novel pathogenic variants in neurodegenerative movement disorders. Thus, we aimed to systematically compare the SV detection capabilities of OGM and ONT in Parkinson's disease.

RNA Sequencing Resolves Cryptic Pathogenic Variants in Mitochondrial Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Mitochondrial diseases are the most common inherited metabolic disorders, characterized by pronounced clinical and genetic heterogeneity that complicates molecular diagnosis. Although DNA‐based sequencing approaches have become standard in genetic testing, up to half of patients remain without a definitive diagnosis.
