In addition to plant-derived, fungal pigments have become an alternative in respect to synthetic ones. Besides sp., several pigment-producing fungi do not have culture conditions well-established yet. In this research, media composition, light wavelength and co-culture were evaluated, results were reported in Absorbance Units per gram of biomass (AU/Bgr). For a C:N ratio above 7 was advantageous, using both complex and defined media; blue LED light increased the AU/Bgr value from 18013 to 344; co-culture did not enhance pigment production. In a high C:N ratio with glucose as carbon source was ideal. When exposing cultures to light, UV and red light gave the highest pigmentation; moreover, differential UV-VIS spectra in all wavelengths suggested production of additional pigments. Particularly a pigment observed when cultured in green light was also found in co-culture with yeast and there was an improvement of AU/Bgr value of 52549%. This is the first report regarding light effect and co-culture for these fungi, as well as C:N ratio for .

Department of plant production and genetics, School of Agriculture, Shiraz University, Shiraz, Iran.
Background: Triticale and tritipyrum as a new artificial cereal were investigated as potential stress-resistant alternatives within the Triticeae tribe due to their notable adaptability to environmental stresses.
Objectives: The first purpose of this study was to determine the genetic variation of 14 genotypes on physiological traits in arid and semi-arid climate of Yazd province on primary trans chromosomal tritipyrum (PTCT) lines, promising triticale lines, and Iranian and Afghan bread wheat cultivars, and the second purpose was to investigate the genetic diversity and classification of genotypes using start codon targeted (SCoT) markers.
Materials And Methods: The photosynthesis pigments, proline, and catalase enzyme activity of 14 genotypes were determined.
CLEC12B regulates melanocyte immunity and homeostasis in the skin through the STAT1/IRF1 axis.

CLEC12B is a C-type lectin receptor involved in the inhibition of natural killers-mediated cytotoxicity. We have previously shown that CLEC12B is predominantly expressed on melanocytes, inhibits melanin production and pigmentation as well as proliferation of melanoma. To date, the role of CLEC12B in skin immunity is unknown.

Background: Amalgamation of metal-tolerant plant growth promoting rhizobacteria (PGPR) with biochar is a promising direction for the development of chemical-free biofertilizers that can mitigate environmental risks, enhance crop productivity and their biological value. The main objective of the work includes the evaluation of the influence of prepared bacterial biofertilizer (BF) on biometric growth parameters as well as physiological and biochemical characteristics of rapeseed ( L.) at copper action.

Introduction: In order to enhance the quality of cigar tobacco leaves (CTLs), a gradient variable temperature fermentation approach was employed.
Methods: The temperature gradient demonstrated a gradual increase from low temperature (35 ± 2°C) to moderate temperature (45 ± 2°C), and then to high temperature (55 ± 2°C). Each temperature gradient underwent a 10-day fermentation process, resulting in a total duration of 30 days.
