Drought-inducible—but ABA-independent—thaumatin-like protein from carrot (Daucus carota L.)

Abstract: Drought treatment induces the accumulation of dcTLP, which is similar in structure to the thaumatin-like proteins (TLPs) found in the embryogenic calli, seedlings, and mature plants of carrot (Daucus carota). We isolated a full-length dcTLP cDNA clone from carrot and characterized the 5' upstream sequences. The coding region of dcTLP consisted of 645 nucleotides; the theoretical pI value was 4.9, and its molecular weight was approximately 22 kDa. The production of dcTLP transcripts in the seedlings increased d… Show more

“…A PR5 gene family in wild peanut (Arachis diogoi) was reported as significantly upregulated in response to infection by Phaeoisariopsis personata (Singh et al 2013). DcTLP from carrot (Daucus carota) was highly expressed in dehydration stress and its promoter was highly activated following drought (Jung et al 2005). TaPR5, a TLP homologue from wheat (Triticum aestivum) notably increased after treatment of wheat leaves with methyl jasmonic (MeJA), salicylic acid (SA) and abscisic acid (ABA) (Wang et al 2010).…”

“…TLP accumulated in wheat via jasmonic acid (JA) and SA signaling against Stagonospora nodorum [26]. Although expression of the dcTLP from Daucus carota was not affected by ABA, SA and JA directly, it had a high level specific to drought stress in the embryogenic calli, seedlings, and mature plants [27]. ABA is considered to be able to modulate gene expression under osmotic-related stress such as freezing, drought and salt, but not all osmotic-induced genes appear to ABA dependent.…”

“…Dehydrin genes and TLP genes play crucial roles in response to abiotic stresses, and may be induced by abiotic stress-related signal molecules such as ABA [51,52,53]. In Arabidopsis, ABA could mediate the expression of dehydration-responsive gene RD22 [50].…”
