Abstract
This is the first study to show that polyamine spermine, a low-molecular-weight nitrogen-containing compound, can induce autophagy in plants. This process is accompanied by an increased generation of reactive oxygen species and nitric oxide, which play a signal role and are required for triggering autophagy.

Efficient regeneration potential is closely related to auxin exposure time and catalase metabolism during the somatic embryogenesis of immature embryos in Triticum aestivum L.

Abstract
Regeneration of cultured tissue is a prerequisite of Agrobacterium- and biolistic-mediated plant transformation. In this study, an efficient protocol for improving wheat (Triticum aestivum L.) immature embryo regeneration was developed. Based on the statistical analysis of embryogenic callus induction efficiency, green spot differentiation efficiency, and plant regeneration efficiency from five wheat accessions, improved culture conditions were found to be more effective for embryogenic callus production than the traditional conditions. Using semi-quantitative reverse transcription polymerase chain reaction, a candidate gene, designated as TaCAT1, which encodes a catalase was identified to have a significant correlation with high-regeneration trait of wheat immature embryos. Three amino acid substitutions were found in TaCAT1 protein between high- and low-regeneration wheat accessions. Hydrogen peroxide content in the cultured calli increased from day 5 to 15, and then decreased sharply on day 20, followed by a second peak on day 25 during regeneration stage. Furthermore, a 3,500-bp 5' flanking region upstream of the first codon ATG of TaCAT1 was isolated using inverse polymerase chain reaction. In silico, analysis revealed that the TaCAT1 promoter contained two regulatory motifs associated with responses to auxin.

Abstract
The level of nitric oxide (NO) in roots of 2-day-old etiolated pea (Pisum sativum L.) seedlings was investigated by fluorescence microscopy using the fluorescent probe 4,5-diaminofluorescein diacetate. Segments representing transversal (cross) cuts of the roots having thickness of 100 to 150 µm (a segment of the root located 10 to 15 mm from the apex) were analyzed. A substantial concentration of NO in the roots was registered when the seedlings were grown in water (control). Addition of 4 mM sodium nitroprusside, 20 mM KNO₃, 2 mM NaNO₂, 2 mM L-arginine into the growth medium increased NO concentration with respect to the control by 1.7- to 2.3-fold. Inhibitors of animal NO-synthase - 1 mM Nω-nitro-L-arginine methyl ester hydrochloride and 1 mM aminoguanidine hydrochloride - reduced the intensity of fluorescence in the root segments in the presence of all the studied compounds. In medium with KNO₃, the inhibitor of nitrate reductase -150 µM sodium tungstate - lowered the fluorescence intensity by 60%. Scavengers of nitric oxide - 100 µM 2-phenyl-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide and 4 µM hemoglobin - lowered NO concentration in all the studied variants. Potassium ferrocyanide (4 mM) as the inactive analog of sodium nitroprusside inhibited generation of NO. These results are discussed regarding possible pathways of NO synthesis in plants.
