“…In recent years, several studies have shown that GUS expressions driven by the promoters of the genes, WOX3, cation-Cl -cotransporter (ccc), DR5, PvACCase, and AtSUC3, were in the same tissues including stipules, leaf hydathodes, leaf apex, root tips, lateral root buds, and anthers [29][30][31][32][33][34]. Several of the genes have also been demonstrated to function in the regulation of free auxin distribution in these tissues.…”

A cotton fiber cDNA, GhRING1, and its corresponding gene have been cloned and characterized. The GhRING1 gene encodes a RING-type ubiquitin ligase (E3) containing 338 amino acids (aa). The GhRING1 protein contains a RING finger motif with conserved cysteine and histine residues at the C-terminus, and is classified as a C(3)H(2)C(3)-type RING protein. Blast searches show that GhRING1 has the highest homology to At3g19950, a zinc finger family protein from Arabidopsis. Real time RT-PCR analysis indicates that the GhRING1 gene is expressed in cotton fibers in a developmental manner. The transcript level of GhRING1 gene reaches a maximum in elongating fibers at 15 days post-anthesis (DPA). In vitro auto-ubiquitination assays using wheat germ extract and a reconstitution system demonstrate that GhRING1 has the ubiquitin E3 ligase activity. The histochemical GUS assay was performed to analyze tissue specificity of the GhRING1 and At3g19950 promoters in transgenic Arabidopsis plants. The GUS assay shows that the promoter of At3g19950 is highly activated in leaves, roots, trichomes, and also in anthers and stigma of flowers. In contrast, the GUS expression directed by the GhRING1 promoter is only located at stipules and anthers. The expression pattern of GhRING1 suggests that protein ubiquitination and turnover may be involved in transition to different stages of cotton fiber development.

“…This enzyme plays an important role in controlling germination efficiency, i.e. seed vigour because: (1) ACCase plays a key regulatory role that catalyses the first committed step in lipid biosynthesis (Post-Beittenmiller et al 1993;Gornicki et al 1994;Sasaki and Nagano 2004) that is essential for resumption of embryonic growth and (2) by an alternative route ACCase drives the secondary biosynthetic pathway for flavonoids (Figueroa-Balderas et al 2006) that function as sun screen (Lois and Buchanan 1994;Landry et al 1995) and also as (nonenzymatic) ROS scavenging antioxidant (Yamasaki et al 1997); remaining un-degraded through structural activity relationship (Amic et al 2003) under (seed storage) stress conditions. It is thus conceivable that flavonoids serve to protect dry seed from maturation through storage to the germination stage (on imbibition).…”

Germination potential, i.e. vigour manifested at sensu stricto germination, was studied in 22 rice varieties to distinguish between the genetic control for low vigour (lv) at fresh harvest and lv after ageing of seeds. For identifying seed vigour-associated DNA marker(s), correlative studies between (1) physiological parameters viz. germination of (a) unaged seeds under optimum and cold stressed condition, (b) aged seeds under optimal condition and (2) growth-associated biochemical parameters viz. alcohol dehydrogenase (ADH) and esterase (EST) activity during early germination of fresh seeds and antioxidant potential in dry embryos of fresh and aged (1 year) seeds were undertaken. ADH and EST activity as well as antioxidant potential showed positive correlation with speed of embryo emergence and early seedling growth of seeds. The reduction of antioxidant potential in aged seeds also appeared proportional to germination performance. Random amplified polymorphic DNA analysis between the varieties was correlated with the abovementioned vigour parameters, using multiple regression analysis. This led to the identification of four bands associated with the vigour trait at 99% significance level; of these, the * 900-bp DNA fragment (named as HVAC 19), through basic local alignment search tool nucleotides analysis, revealed a sequence homology with acetyl CoA carboxylase (ACCase) gene of wheat at 94% similarity level.

“…Among them, both cytosolic acetyl-CoA carboxylase (Acc-2) (Xscszm17 -FJ436983.1; Xscszm18 -EU660895.1) and plastid acetyl-CoA carboxylase (Acc-1) (Xscszm49 -EU660897.1) constitute an important element of plant response to various kinds of stresses, including nutrition. Acetyl-CoA carboxylase (ACCase; EC 6.4.1.2) catalyzes the ATP-dependent formation of malonyl-CoA from acetyl-CoA and bicarbonate (Figueroa-Balderas et al 2006). Malonyl-CoA is essential for fatty acid synthesis which occurs in plastids (Harwood, 1988).…”

Background: An adaptive mechanism in plant roots is initiated in the event of nitrogen and potassium deficiency, and it facilitates the active uptake of these elements in order to ensure plant growth and survival in stress conditions. Signaling and transduction of signals in response to changing nitrogen and potassium concentrations is a complex process, affected by interactions between various gene expression products, and often subjected to modifications. Results: In order to identify genotypic differences between phenotypes of two populations of recombinant inbred rye lines (153/79-1 x Ot1-3 and Ot0-6 x Ot1-3) in response to nutrition stress caused by nitrogen and potassium deficiency at the seedling stage, bulk segregant analysis was utilized. Identification of genotypic differences between and within pooled DNA samples involved 424 RAPD, 120 ISSR primers and 50 combinations of R-ISSR. Identified markers were sequenced and converted to SCAR, attributing to them unique ESTs annotations, and chromosomal ones to selected localizations. Significant relationships with the examined trait were described for nine and eight RAPD markers, four and five ISSR, one and three R-ISSR markers for population 153/79-1 x Ot1-3 and Ot0-6 x Ot1-3, respectively. Sequences identified for the rye genome were characterized by a uniqueness and a similarity to the sequence of aquaporin PIP1, a gene encoding protein related to the function of the transcription factor in plant response to iron deficiency and the putative ethylene-responsive transcription factor, cytosolic acetyl-CoA carboxylase, HvHKT1 transporter, as well as HCBT proteins. Conclusion: Identified molecular markers differentiating rye genotypes of extreme response of root system on nitrogen and potassium deficiency play a significant role in systemic plant response to stress, including stress caused by nitrogen and potassium deficiency. They may constitute a system facilitating selection, and together with the material they are described in, they may be a starting point for research on mechanisms of sensing and transduction of signal across the plant.
