Chitosan derivatives induce local and distal expression of defence-related genes in wheat (Triticum aestivum L.) seedlings Agrociencia
Díaz-Martínez,Juan M.; Aispuro-Hernández,Emmanuel; Vargas-Arispuro,Irasema; Falcón-Rodríguez,Alejandro B.; Martínez-Téllez,Miguel Á..
Abstract Chitosan and its derivatives are elicitors of defence responses in plants. The physical and chemical characteristics, like the molecular weight and acetylation degree determine the type of effect and specificity. Although chitosan-induced biochemical and enzymatic reactions in wheat (Triticum aestivum) are reported, the transcriptional activation of defensive markers by chitosan derivatives remains unaddressed. The hypothesis of our study was that the different structural features of chitosan derivatives would influence the transcriptional patterns related to protective responses in wheat. The aim of our study was to compare the local and systemic inductive properties of chitosan and chitooligosaccharides (COS) in wheat seedlings through the...

Compounds Derived from Garlic as Bud Induction Agents in Organic Farming of Table Grape Chilean J. Agric. Res.
Vargas-Arispuro,Irasema; Corrales-Maldonado,Consuelo; Martínez-Téllez,Miguel Ángel.
Viticulture is one of the most important economic activities in the Northwest of Mexico. A major obstacle for the economic production is the insufficient period of chilling temperatures. This problem leads to poor budbreak, which in turn results in reduced yields. This problem is aggravated when plants are cultivated using the organic farming system, mostly because there are not organically approved restbreaking agents. In this work different products derived from garlic (Allium sativum L.) were obtained and evaluated as stimulate budbreak agent of table grape (Vitis vinifera L.) cvs. Flame Seedless and Perlette. The isolated compounds were chemically identified and include allicin, diallyl disulfide, diallyl trisulfide, 3-vynil-[4H]-1,2-ditiin and...

Total RNA quality of lyophilized and cryopreserved dormant grapevine buds Electron. J. Biotechnol.
García-Baldenegro,Claudia Vanessa; Vargas-Arispuro,Irasema; Islas-Osuna,María; Rivera-Domínguez,Marisela; Aispuro-Hernández,Emmanuel; Martínez-Téllez,Miguel Ángel.
Background Plant tissues must be preserved in their collection state, especially for genome-wide expression profile studies. Lyophilization is a feasible, affordable tool when fresh tissues cannot be shipped at ultralow temperatures from their origin to the place of analysis. In this study, the total RNA quality of dormant grapevine buds (Vitis vinifera L. cv. ‘Flame Seedless’) of freeze-dried samples stored at room temperature conditions was evaluated and compared to that of cryopreserved (-80°C) grapevine buds. Results Good yield and quality of RNA were obtained from freeze-dried dormant buds stored at room temperature for 0, 3 and 6 weeks after they were lyophilized. Further experiments confirmed that the extracted total RNA could be used for actin and...
