Brassinosteroid signaling network: implications on yield and stress tolerance. (2013). doi: 10.1007/s00425-009-1042-z, Tang, W., Charles, T. M., and Newton, R. J. (2011). 29, 259263. Brassinosteroids-induced systemic stress tolerance was associated with increased transcripts of several defence-related genes in the phloem in Cucumis sativus. In the spring barley (Hordeum vulgare L.), heat stress enhances the expression of HSPs. JA is also implicated in plant responses to abiotic stress (such as soil salinity, wounding and UV).

Relationship between PSII activity, CO2 fixation, and Zn, Mn and Mg contents of Lolium perenne under zinc stress. Natl. (2008). Although ascorbate and glutathione both function as cofactors of enzymatic antioxidants, both can also directly quench ROS and regulate the gene expression associated with biotic and abiotic stress responses (Hossain et al., 2012a,b). The MTP11 and MTP8 were found to be close homologs of ShMTP8 (formerly ShMTP1) and confirmed Mn tolerance in A. thaliana (Delhaize et al., 2003), thus suggesting a role of these proteins in metal tolerance.

(2013b). For instance, in Brassica juncea, As causes toxicity by changing the levels of the auxins:indole-3-acetic acid (IAA), indole-3- butyric acid (IBA), and naphthalene acetic acid (NAA) and altering the expression of about 69 microRNAs (Srivastava et al., 2013).

Consequently, the ABA-deficient mutant plants show impaired heat tolerance, which can be reversed by exogenous addition of ABA (Larkindale and Knight, 2002). Res. The airborne ET may reduce thermotolerance of holm oak (Quercus ilex) plants to heat stress by deterring antioxidant defenses (Munn-Bosch et al., 2004). A well-known example of a specialist animal is the monophagous koala, which subsists almost entirely on eucalyptus leaves. (2012). ABA treatment increases the expression levels of tall fescue heat stress transcription factor A2c (FaHSFA2c). However, in anaerobic paddy fields, As (mainly Arsenite) uptake is regulated by transporters of Si, namely Lsi1 (low silicon 1; influx transporter) and Lsi2 (low silicon 2; efflux transporters) (Ma et al., 2008).
