Numerous studies have shown that the endophytic fungus Piriformospora indica has a broad range of promoting effects on root development and plant growth in host plants. However, there are currently no reports on the application of this fungus on Cerasus humilis. This study first compared the colonization ability of P. indica on 11 C. humilis varieties and found that the colonization rate of this fungus on these varieties ranged from 90% to 100%, with the colonization rate of the varieties ‘09-01’ and ‘Nongda 7’ being as high as 100%. Subsequently, the effect of P. indica on root development and plant growth of C. humilis was investigated using cuttings of ‘09-01’ and ‘Nongda 7’ as materials. P. indica colonization was found to increase the biomass of ‘09-01’ and ‘Nongda 7’ plants; root activity, POD enzymes, and chlorophyll content were also significantly increased. In addition, indole-3-acetic acid (IAA) content in the roots of C. humilis plants increased after colonization, while jasmonic acid (JA) and 1-aminocyclopropane-1-car- boxylic acid (ACC) content decreased. In conclusion, it has been demonstrated that P. indica can promote the growth of C. humilis plants by accelerating biomass accumulation, promoting rooting, and enhancing the production of photosynthetic pigments, as well as regulating hormone synthesis.

“…Combined with molecular biology these new systems have the potential to extend and reshape traditional light harvesting capacity. Research related to harvesting far red light and inputting that energy into the photosynthetic process started with the discovery of chlorophyll d reaction center systems in photosynthetic bacteria ( Allakhverdiev et al., 2016 ; Scheer, 2022 ), and has since been extended to chlorophyl f and infrared absorbing proteorhodopsin. In the other direction, in a spectral sense, the concept of “filling the green gap” makes intuitive sense as most major pigments absorb weakly in some portion of the 500-600 nm region, and this represents a significant portion of the total irradiance that reaches the Earth’s surface ( Gundlach et al., 2009 ).…”

Current work in photosynthetic engineering is progressing along the lines of cyanobacterial, microalgal, and plant research. These are interconnected through the fundamental mechanisms of photosynthesis and advances in one field can often be leveraged to improve another. It is worthwhile for researchers specializing in one or more of these systems to be aware of the work being done across the entire research space as parallel advances of techniques and experimental approaches can often be applied across the field of photosynthesis research. This review focuses on research published in recent years related to the light reactions of photosynthesis in cyanobacteria, eukaryotic algae, and plants. Highlighted are attempts to improve photosynthetic efficiency, and subsequent biomass production. Also discussed are studies on cross-field heterologous expression, and related work on augmented and novel light capture systems. This is reviewed in the context of translatability in research across diverse photosynthetic organisms.

A suitable case study is farnesol, the ester-bound alcohol side chain of bacteriochlorophyll c , d , e (Scheer, 1991 ), and g (Airs et al , 2001 ), which are light-harvesting pigments more or less specific of green sulfur ( c , d , and e ) (Caple et al , 1978 ), non-sulfur ( c and d ) (Gloe and Risch, 1978 ), or purple sulfur bacteria. Thus, relatively high values of stable carbon isotope fractionation in farnesol (δ 13 C values of ca.…”

An Overview of Lipid Biomarkers in Terrestrial Extreme Environments with Relevance for Mars Exploration

et al. 2023

Lipid molecules are organic compounds, insoluble in water, and based on carbon-carbon chains that form an integral part of biological cell membranes. As such, lipids are ubiquitous in life on Earth, which is why they are considered useful biomarkers for life detection in terrestrial environments. These molecules display effective membrane-forming properties even under geochemically hostile conditions that challenge most of microbial life, which grants lipids a universal biomarker character suitable for life detection beyond Earth, where a putative biological membrane would also be required. What discriminates lipids from nucleic acids or proteins is their capacity to retain diagnostic information about their biological source in their recalcitrant hydrocarbon skeletons for thousands of millions of years, which is indispensable in the field of astrobiology given the time span that the geological ages of planetary bodies encompass. This work gathers studies that have employed lipid biomarker approaches for paleoenvironmental surveys and life detection purposes in terrestrial environments with extreme conditions: hydrothermal, hyperarid, hypersaline, and highly acidic, among others; all of which are analogous to current or past conditions on Mars. Although some of the compounds discussed in this review may be abiotically synthesized, we focus on those with a biological origin, namely lipid biomarkers. Therefore, along with appropriate complementary techniques such as bulk and compound-specific stable carbon isotope analysis, this work recapitulates and reevaluates the potential of lipid biomarkers as an additional, powerful tool to interrogate whether there is life on Mars, or if there ever was.
