The formation of multifunctional vascular tissues represents a significant advancement in plant evolution. Differentiation conductive cells is specific, involving two main pathways, namely protoplast clearance and cell wall modification. In xylogenesis, autophagy crucial process for complete elimination tracheary elements, whose also undergoes strong changes. Knowledge pertaining to living sieve which lose most their during phloemogenesis, remains limited. We hypothesized that plays role,...
Abstract Background and Aims The transformation of sieve elements from meristematic cells, equipped with a full complement organelles, to specialized transport tubes devoid nucleus has long been enigmatic. We hypothesized strong involvement various degradation pathways, particularly macroautophagy in this context, emphasizing the importance autophagic selectivity remaining viability these cells. Methods Experiments were performed on pioneer roots Populus trichocarpa cultivated rhizotrons...
Beech seeds are produced irregularly, and there is a need for long-term storage of these forest management practices. Accumulated reactive oxygen species broadly oxidize molecules, including amino acids, such as methionine, thereby contributing to decreased seed viability. Methionine oxidation can be reversed by the activity methionine sulfoxide reductases (Msrs), which enzymes involved in regulation many developmental processes stress responses. Two types Msrs, MsrB1 MsrB2, were...
Although both subspecies of Pteridium aquilinum (subsp. and subsp. pinetorum) are widespread in Poland, our knowledge about the occurrence significance extrafloral nectaries on frond stipes (petioles) is very limited. Their loca¬tion abaxial stipe surface pairs at subsequent pinna-bases often overlooked. The study concerns morphological/ anatomical structure, distribution, function bracken nectaries. Observations sugar secretions their local associations with ants indicated a dependence age,...
Abstract Two subspecies of Pteridium aquilinum (L.) Kuhn: subsp. and pinetorum occurring in Poland have been studied with respect to their micromorphological traits, order facilitate differentiation. The micromorphology marginal sori typical are described. Differences were found the width outer membrane indusium, features its edge (straight/notched) size shape indusium cells. Moreover, differentiating turned out be frequency length cillia on indusium.
The paper presents a new locality of Cephalanthera rubra identified in summer 2015 the Milicz Forest District, northern Lower Silesia, as well describes potential threats, characteristics and habitat population.
