Morphogenetic response of shoot tips to cryopreservation by encapsulation-dehydration in a solid mutant and periclinal chimeras of Chrysanthemum × grandiflorum /Ramat./Kitam.

Cryopreservation is widely applied to many economically important species excluding chimera plants which are problematic for long-term conservation. Their storage problems can be circumvented only by cryopreserving meristems. This study looked at the morphogenetic response of shoot tips of periclinal chimera chrysanthemum ‘Lady Orange’ and ‘Lady Salmon’, as well as the solid mutant ...

Effect of TIBA, fluridone and salicylic acid on somatic embryogenesis and endogenous hormone and sugar contents in the tree fern Cyathea delgadii Sternb.

Somatic embryogenesis (SE) in the tree fern Cyathea delgadii was first described in 2015 and since then has been used to exploration of this phenomenon in cryptogamic plants. To deepen the knowledge about the hormonal control of SE, stipe explants were cultured on media supplemented with hormone biosynthesis and transport inhibitors (HBTIs). In the presence of 30 µM ...

Interplay between nitric oxide, ethylene, and gibberellic acid regulating the release of Amaranthus retroflexus seed dormancy

A very small percentage, below 10%, of Amaranthus retroflexus seeds were germinated at 25 °C in the light and thus the seeds were considered to be primary dormant. Nitric oxide (NO) applied for only 5 h stimulated germination of these non-deep physiologically dormant seeds. Likewise, ethephon, ethylene, 1-aminocyclopropane-1-carboxylic acid (ACC) and gibberellic acid (GA3) induced ...

Proton kinetics through the cuticle layer in maize

A Monte Carlo simulation was used to determine the dependence between the thickness of the cuticle layer of coleoptiles and the spectra of the H+ ions (i.e., protons) passing through this layer, which is treated as a potential barrier. The apparently simplistic model of a walled cylinder filled with H+ ions propagating through the cuticle layer was solved in silico. We showed that ...

Signalling regulators of abscisic and gibberellic acid pathways are involved in dormancy breaking of Norway maple (Acer platanoides L.) seeds

Physiological dormancy is a characteristic of the seeds of plants that are exposed to adverse harsh environmental conditions. Many tree seeds from the northern hemisphere have acquired deep dormancy as an adaptation to the winter period. Such kinds of dormancy can be removed by cold stratification. This physiological process is regulated through abscisic and gibberellic acids ...

Bioinformatic identification and expression analysis of new microRNAs from wheat (Triticum aestivum L.)

As an essential regulatory component in plants, microRNAs (miRNAs) have been intensively studied over the past decade. Although hundreds of miRNAs have been identified and analyzed in many important crops and model plants, very little is known about the function of common wheat (Triticum aestivum L.) miRNAs. In this study, we performed computational prediction of novel wheat miRNAs ...

Spontaneous action potentials and circumnutation in Helianthus annuus

Action potentials (APs) in plants are involved in fast leaf or trap closure as well as elongation, respiration, photosynthesis, and fertilization regulation. Here, spontaneous APs (SAPs) in relation to endogenous stem movement named circumnutation (CN) have been investigated in Helianthus annuus in different light conditions in freely circumnutating and immobilized plants. ...

Polyamines in yellow lupin (Lupinus luteus L.) tolerance to soil drought

Polyamines (PAs) are related to many physiological processes, including soil drought stress. Two yellow lupin ‘Morocco 4’ (drought tolerant) and ‘Taper’ (drought sensitive) were exposed to soil drought for 2 weeks. The half of the examined plants were additionally sprayed with a solution of polyamine biosynthesis inhibitor—dl-α-difluoromethylarginine (DFMA). Yellow lupin leaves ...

ABA pretreatment can limit salinity-induced proteome changes in growing barley sprouts

A proteomic study was conducted on caryopses of barley cv. Stratus (Hordeum vulgare). The caryopses were germinated in darkness at 20 °C, according to one of the three experimental setups: (a) in distilled water for 24 h, followed by 100 mM NaCl for another 24 h (salinity stress, SS); (b) in 100 µM abscisic acid for 24 h, with rinsing in distilled water to remove residual ABA, ...

Males and females of Juniperus communis L. and Taxus baccata L. show different seasonal patterns of nitrogen and carbon content in needles

Genders of dioecious species often show secondary sexual dimorphisms (not directly related to the sex organs), which may be related to reproductive demand for resources during the year. Our working hypothesis stated that phenology influences yearly sex-specific pattern of foliar nitrogen concentration in dioecious species. The concentration of carbon (C) and nitrogen (N) of last ...

Salicylic acid accumulation as a result of Cu, Zn, Cd and Pb interactions in common reed (Phragmites australis) growing in natural ecosystems
