The effects of phenylpropanoid deficiency on plant growth, photosynthetic efficiency the photosystem II and freezing tolerance leaves were studied during acclimation winter oilseed rape plants ( Brassica napus L. var. oleifera cv Jantar) at low temperature. Application 2‐amino‐2‐indanophosphonic acid inhibited phenylalanine ammonia‐lyase (E.C. 4.3.1.5) activity by about 90%. This was followed a marked reduction soluble phenolics (in particular hydroxycinnamic acids) anthocyanins in leaves....
Background and AimsThe hypothesis was tested that pectin content methylation degree participate in regulation of cell wall mechanical properties this way may affect tissue growth freezing resistance over the course plant cold acclimation de-acclimation.
The cell wall emerged as one of the important structures in plant stress responses. To investigate effect cold on properties, content and localization pectins pectin methylesterase (PME) activity, were studied two maize inbred lines characterized by different sensitivity to cold. Low temperature (14/12 °C) caused a reduction PME activity leaves chilling-sensitive line, especially after prolonged treatment (28 h 7 days). Furthermore, immunocytohistological studies, using JIM5 JIM7 antibodies,...
Recent progress in selective breeding of maize (Zea mays L.) towards adaptation to temperate climate has allowed the production inbred lines withstanding cold springs with temperatures below 8 °C or even close 0 °C, indicating that despite its tropical origins is not inherently cold-sensitive. Here we studied acclimatory response three contrasting cold-sensitivity selected basing on multi-year routine field data. The observations were confirmed growth chamber. Under controlled conditions...
Plants mainly utilize inorganic forms of nitrogen (N), such as nitrate (NO3-) and ammonium (NH4⁺). However, the composition N source is important, because excess NH4⁺ promotes morphological disorders. cultured on sole exhibit serious growth inhibition, commonly referred to "ammonium toxicity syndrome." NH4⁺-mediated suppression may be attributable both repression cell elongation reduction division. The precondition for enlargement expansion wall, which requires loosening wall polymers....
In maize seedlings, severe cold results in dysregulation of circadian pattern gene expression causing profound modulation transcription genes related to photosynthesis and other key biological processes. Plants live highly cyclic life their response environmental stresses must allow for underlying rhythms. To study the interplay a stress rhythmic cue we investigated transcriptomic seedlings low temperature context diurnal expression. Severe had pronounced effect on rhythm substantial...
The aim of the presented investigation was to describe seasonal changes microbial community composition in situ different biocenoses on historical sandstone Northern Pergola Museum King John III’s Palace at Wilanow (Poland). biodiversity analyzed by application Illumina-based next-generation sequencing methods. metabarcoding analysis allowed for detecting lichenized fungi taxa with clear domination two genera: Lecania and Rhinocladiella. It also observed that, during winter, richness fungal...
In the years 2018‒2020, effectiveness of three synthetic active substances (acequinocyl, fenpyroximate, spirodiclofen), one substance derived from Streptomyces spp. (abamectin), a plant extract (orange oil) and silicone polymers in controlling Phyllocoptes gracilis two Polish raspberry plantations (v. ‘Glen Ample’) was assessed. All showed high comparable efficacy against tested pest, significantly reducing its population. However, their effects occurred at different times after application....
