How ELONGATED HYPOCOTYL5 helps protect plants from UV-B rays.
Most of us do what we can to avoid the DNA-damaging effects of UV-B rays. While plants can’t slap on sunscreen, put on a nice hat, or move to a shady spot, they too have ways to protect themselves from (and acclimate to) damaging UV-B radiation. For example, plants undergo UV-B-dependent photomorphogenic changes (see figure), including reduced hypocotyl and leaf expansion, increased stomatal cl...
متن کاملGlutathione and ascorbic acid protect Arabidopsis plants against detrimental effects of iron deficiency.
Iron is an essential micronutrient required for a wide variety of cellular functions in plant growth and development. Chlorosis is the first visible symptom in iron-deficient plants. Glutathione (GSH) and ascorbic acid (ASC) are multifunctional metabolites playing important roles in redox balancing. In this work, it was shown that GSH and ASC treatment prevented chlorosis and the accumulation o...

متن کاملUV-B radiation effects on terrestrial plants – A perspective
Both terrestrial and aquatic plants, the primary producers supporting life on earth, can be threatened by global climate change and particularly by UV-B radiation due to the depletion of the ozone layer in both Poles. The injurious effects of UV-B have been assessed mainly through in vitro studies and vary greatly according the dose received, the exposition period and the sensitivity of the spe...
متن کاملOxalate-degrading bacteria can protect Arabidopsis thaliana and crop plants against botrytis cinerea.
Botrytis cinerea and Sclerotinia sclerotiorum secrete oxalic acid as a pathogenicity factor with a broad action. Consequently, it should be possible to interfere with the infection process by degrading oxalic acid during the interaction of these pathogens with their hosts. We have evaluated the potential of oxalate-degrading bacteria to protect plants against pathogenic fungi. Such bacteria wer...
