Influence of NaCl treatments on growth and biochemical parameters of castor bean (Ricinus communis L.)

open access: yesActa Agriculturae Slovenica, 2012
Castor bean (Ricinus communis L.) is widely cultivated throughout the world for use as a medicinal plant and oil consumption purposes; however its salt tolerance has not been clarified.

On Approximating Restricted Cycle Covers [PDF]

open access: yes, 2006
A cycle cover of a graph is a set of cycles such that every vertex is part of exactly one cycle. An L-cycle cover is a cycle cover in which the length of every cycle is in the set L. The weight of a cycle cover of an edge-weighted graph is the sum of the

Methionine Sulfoxide Reductase B Regulates the Activity of Ascorbate Peroxidase of Banana Fruit

open access: yesAntioxidants, 2021
Ascorbate peroxidase (APX) is a key antioxidant enzyme that is involved in diverse developmental and physiological process and stress responses by scavenging H2O2 in plants. APX itself is also subjected to multiple posttranslational modifications (PTMs).

Characteristics of chlorophyll fluorescence and antioxidative system in super-hybrid rice and its parental cultivars under chilling stress

open access: yesBiologia Plantarum, 2010
Characteristics of chlorophyll fluorescence and antioxidative system were investigated in rice (Oryza sativa L.) super-hybrid Liangyoupeijiu (LYPJ), maternal cultivar Peiai64s, and paternal cultivar indica rice 9311 under chilling stress.

On unrooted and root-uncertain variants of several well-known phylogenetic network problems [PDF]

open access: yes, 2016
The hybridization number problem requires us to embed a set of binary rooted phylogenetic trees into a binary rooted phylogenetic network such that the number of nodes with indegree two is minimized.

Multi-omic characterization of bifunctional peroxidase 4-coumarate 3-hydroxylase knockdown in Brachypodium distachyon provides insights into lignin modification-associated pleiotropic effects

open access: yesFrontiers in Plant Science, 2022
A bifunctional peroxidase enzyme, 4-coumarate 3-hydroxylase (C3H/APX), provides a parallel route to the shikimate shunt pathway for the conversion of 4-coumarate to caffeate in the early steps of lignin biosynthesis.

Oracle Complexity Classes and Local Measurements on Physical Hamiltonians [PDF]

open access: yes, 2019
The canonical problem for the class Quantum Merlin-Arthur (QMA) is that of estimating ground state energies of local Hamiltonians. Perhaps surprisingly, [Ambainis, CCC 2014] showed that the related, but arguably more natural, problem of simulating local ...

Molecular characterization and transcriptional profiling suggested structural and functional divergence in ascorbate peroxidase (APX) and APX-related (APX-R) genes in Triticum aestivum L. [PDF]

open access: yes, 2019
Abstract Background: Ascorbate peroxidases (APXs) are heme-dependent H2O2 scavenging enzymes providing the antioxidant defense and regulating myriad biological processes. APX-related (APX-R) is an additional form of APX protein which lacks peroxidase activity but form dimer with the chloroplastic APX (chlAPX).
