The importance of cyanobacterial polysaccharides of biological soil crusts in sand surface stabilization and soil nutrient retention has been long acknowledged. However, the role of cyanobacterial polysaccharides as a source of nutrition to vascular plants in crusted areas is ignored. In this study, the chemical composition of the polysaccharide sy...

... Ціанобактерії відомі своєю здатністю переносити високий рівень водного дефіциту в оточуючому середовищі (Caiola et al., 1996). Вони стійкі до зневоднення завдяки різноманітним захисним механізмам клітини, а саме: модифікації структури та складу оболонки клітин, зменшенню дихання (Potts, 1994); зниженню регуляції фотосинтезу (Harel et al., 2004), виробленню ферментів, які усувають активні форми кисню (Chen et al., 2012), а також поглинають ультрафіолет і захищають від сонячної радіації (Roos, Vincent, 1998); накопичуючі цукри, такі як трегалоза, стабілізують ліпідні мембрани (Klähn, Hagemann, 2011;Chen et al., 2012), виділяючи позаклітинні полісахариди, що утримують вологу та запобігають висиханню (Tamaru, Takani, 2005). ...
... Additionally, cyanobacteria can directly influence the development and establishment of vascular plants through the production and release of biologically active molecules, like extracellular polymeric substances (EPS) [25,26], vitamins [27,28], proteins and amino acids [29], as well as phytohormones [30]. This influence can be, on one hand, positive, with several studies reporting that biomolecule-producing cyanobacteria promote germination, root length, shoot length, fresh weight, and dry weight, and other physiological parameters such as pigment content or phytohormone pool [29,31,32]. ...
... They increase soil fertility in dryland regions ( Zhao et al., 2010), where N, together with water, is a major limiting factor for ecosystem functioning (Noy-Meir, 1973). Cyanobacteria also provide a favorable microhabitat for soil biota ( Liu et al., 2011) and improve vascular and annual plant performance ( Xu et al., 2013;Lan et al., 2014). Due to these features and their high pervasiveness in every environment on Earth, cyanobacteria can be rightfully encompassed between ecosystem engineers, and regarded as potential soil restoration tools in drylands ( Rossi et al., 2017). ...
