Expression of some stress-responsive genes in tomato plants treated with ABA and sulfonamide compounds. Leila Zeinali Yedegari1 and Nayer Mohammadkhani2*
Drought causes an increase in some gene expression in plant tissues such as plasma membrane intrinsic proteins type 1 (PIP1), 9-cis-epoxycarotenoid dioxygenase (NCED) SlAREB1. The effects of exogenous abscisic acid (ABA) and two sulfonamide compounds, namely, sulfacetamide (Sa) and sulfasalazine (SS) were studied on gene expression of tomato (Lycopersicon esculentum Mill. Cv. Super chief) under...
متن کاملComplementation of notabilis, an abscisic acid-deficient mutant of tomato: importance of sequence context and utility of partial complementation
The abscisic acid (ABA)-deficient tomato mutant notabilis (not) is believed to be a null mutation in the gene LeNCED1 , encoding a 9cis -epoxycarotenoid dioxygenase involved in ABA biosynthesis. We have sequenced and analysed a 19 kb genomic clone containing LeNCED1 and 5.4 kb of its promoter. This clone was transferred to not homozygotes and several non-wilty transformed plants were obtained. ...
متن کاملEffect of Salinity Stress on Germination in Lycopersicon esculentum L. var Cal-ji
The response of tomato genotype Cal-ji against five salinity levels (distilled water as control, 25, 50, 75 and 100 mM) were studied at germination and early seedling stages. An experiment with conducted by using a completely randomized design (CRD) with three replications. Shoot and root length, shoot and root fresh weight, seed vigor, mean germination time, germination percentage an...
متن کاملPromotion of Germination Using Hydroxamic Acid Inhibitors of 9-cis-Epoxycarotenoid Dioxygenase
Abscisic acid (ABA) inhibits seed germination and the regulation of ABA biosynthesis has a role in maintenance of seed dormancy. The key rate-limiting step in ABA biosynthesis is catalyzed by 9-cis-epoxycarotenoid dioxygenase (NCED). Two hydroxamic acid inhibitors of carotenoid cleavage dioxygenase (CCD), D4 and D7, previously found to inhibit CCD and NCED in vitro, are shown to have the novel ...
متن کاملEffect of Organic Fertilizer and Irrigation Intervals on the Yield and Quality of Cherry Tomato (Solanum lycopersicon var. cerasiforme)
To investigate the effects of organic fertilizers and irrigation frequencies on yield and quality of cherry tomato an experiment was conducted using six fertilizer doses including control (no fertilizer), NPK fertilizer (urea at 300 kg, TSP 200 kg and MoP 250 kg), cow-dung at 5 t ha-1, cow-dung at 10 t ha-1, poultry manure at 5 t ha-1 and poultry manure at 10 t ha-1 with two levels of irrigatio...
