Morphogenesis in Trichoderma : Suppression of Photoinduction by 5-Fluorouracil
Science, 1966Sporulation in the fungus Trichoderma viride is inducible with a short light pulse. 5-Fluorouracil applied prior to photoinduction and removed thereafter suppressed sporulation without greatly affecting growth. This compound also halved the rate of incorporation of uracil-C 14 into RNA but ...

Photoinduction of long-lived polarons
Science, 2015Polaron Dynamics Photosynthetic complexes and organic photovoltaics can rapidly create separated charges upon photoexcitation. However, unproductive charge recombination often occurs in the human-made system. This is in part because the charge acceptor and donor structures are much larger. Huber et al.

Entropy Transduction On Photoinduction
Proceedings of the Annual International Conference of the IEEE Engineering in Medicine and Biology Society Volume 13: 1991, 2005The transduction process is related with the characteristic change of entropy and system dissipation. Under the influence of photoinduction of the Fish - Anabas Testudineus, it is possible to estimate the transduction phase of the topological organisations in relation to the receptor organ of the fish. The entropy function, though difficult to estimate

Photoinduction of carotenoid synthesis of a mycobacterium sp.
Biochimica et Biophysica Acta, 1962Abstract The photoinduced carotenoid synthesis of a Mycobacterium sp. has been studied and found to closely resemble the same phenomenon that has been reported to occur in Neurospora crassa . It has been possible to divide photoinduced carotenogenesis of this Mycobacterium sp. into three distinct phases. 1. 1.

PHOTOINDUCTION OF PROTOPERITHECIA IN NEUROSPORA CRASSA BY BLUE LIGHT
Photochemistry and Photobiology, 1983AbstractBlue light induces the formation of Neurospora crassa protoperithecia.This photoinduction is completed in less than 24 h. Its threshold is about 4.2 J/m2. Red light is ineffective. The Bunsen‐Roscoe law is obeyed at the fluence of 12.6 J/m2 for fluence rates from 5.25 × 10 2 to 1.05 W/m2.

Photoinduction of glycoalkaloids in cured potatoes
American Potato Journal, 1981Curing of Sebago potatoes for 10 days at 25°C prior to common storage at 5°C, reduced the responsiveness of tubers to photoinduced glycoalkaloid synthesis. Continuous illumination with 15 and 25-Watt incandescent light for 10 days increased glycoalkaloid content of peelings (12–14% of tuber weight) in uncured potatoes by a factor of 3.2 and 2.8 ...

[25] Photoinduction of carotenoid biosynthesis
1993Publisher Summary The biosynthesis of carotenoids is almost universally regulated by light. A partial explanation is provided by the role of carotenoids in photosynthesis. Light is a source of information for many organisms that do not use it as a source of energy.

Photoinductive efficiency of soil extracted humic and fulvic acids
Chemosphere, 2002Humic and fulvic acids extracted from soils of different genesis were investigated for their ability to photoinduce the transformation of fenuron (2 x 10(-4) mol(-1)) at 365 nm. The ratio of the initial rate of fenuron consumption over the rate of light absorption by humic substances was found to be higher for fulvic acids (range 2.0 x 10(-3) to 9.0 x ...

Shape Evolution of Silver Nanoplates through Heating and Photoinduction
ACS Applied Materials & Interfaces, 2013Shape conversions of silver nanoplates were realized by heating and subsequent light irradiation. The initial silver nanoprisms were transformed into silver nanodisks gradually in the process of heating, which was possibly achieved through dissolving and readsorption of silver atoms on the surface of silver nanoplates.
