Developing Transgenic Jatropha Using the SbNHX1 Gene from an Extreme Halophyte for Cultivation in Saline Wasteland

et al. 2013

Jatropha is an important second-generation biofuel plant. Salinity is a major factor adversely impacting the growth and yield of several plants including Jatropha. SbNHX1 is a vacuolar Na+/H+ antiporter gene that compartmentalises excess Na+ ions into the vacuole and maintains ion homeostasis. We have previously cloned and characterised the SbNHX1 gene from an extreme halophyte, Salicornia brachiata. Transgenic plants of Jatropha curcas with the SbNHX1 gene were developed using microprojectile bombardment mediated transformation. Integration of the transgene was confirmed by PCR and Rt-PCR and the copy number was determined by real time qPCR. The present study of engineering salt tolerance in Jatropha is the first report to date. Salt tolerance of the transgenic lines JL2, JL8 and JL19 was confirmed by leaf senescence assay, chlorophyll estimation, plant growth, ion content, electrolyte leakage and malondialdehyde (MDA) content analysis. Transgenic lines showed better salt tolerance than WT up to 200 mM NaCl. Imparting salt tolerance to Jatropha using the SbNHX1 gene may open up the possibility of cultivating it in marginal salty land, releasing arable land presently under Jatropha cultivation for agriculture purposes. Apart from this, transgenic Jatropha can be cultivated with brackish water, opening up the possibility of sustainable cultivation of this biofuel plant in salty coastal areas.

SUMMARY:One hundred and eleven accessions of linseed germplasm belonging to 32 districts of six states (Bihar, Chhattisgarh, Himachal Pradesh, Jharkhand, Madhya Pradesh and Maharashtra) in India were characterized for five qualitative and six quantitative traits. Significant variability was observed in the agro-morphological and qualitative traits. The Shannon diversity index varied from 0.23-0.70 and the phenotypic coefficient of variation ranged from 6.0% to 37.1%. IC 345425, an accession from Surgaon, Chandrapur, Maharashtra, was identified as promising for its high oil content (41.5%). The Pearson correlation matrix generated for the quantitative traits indicated that positive and high correlation was observed among days to 50% flowering and days to 80% maturity (0.9; P value <0.0001), plant height and seed weight (0.7; P value <0.0001), seed weight and oil% (0.6; P value <0.0001), seed weight and number of capsules per plant (0.5; P value <0.0001). Two major clusters were formed when the characterization data was subjected to Ward's minimum variance method. DIVA-GIS approaches for the analysis of the diversity in linseed germplasm were mapped for quantitative traits such as plant height, number of capsules per plant and seed oil content.KEYWORDS: DIVA-GIS; Diversity; Flax; Germplasm; India-Linseed RESUMEN: Análisis de la diversidad morfológica y contenido de aceite del germoplasma de linaza india. Ciento once accesiones de germoplasma de semillas de lino pertenecientes a 32 distritos de seis estados de la India (Bihar, Chhattisgarh, Himachal Pradesh, Jharkhand, Madhya Pradesh y Maharashtra) se caracterizaron mediante cinco determinaciones cualitativas y seis cuantitativas. Se observó una variabilidad significativa tanto en los rasgos cualitativos como cuantitativos. El índice de diversidad de Shannon varió entre 0,23-0,70 y el coeficiente de variación fenotípica varió entre 6,0 y 37,1 %. IC-345425, una accesión a partir Surgaon, Chandrapur, Maharashtra fue identificado como prometedora, por su alto contenido de aceite (41,5 %). La matriz de correlación de Pearson generado para los rasgos cuantitativos indicaron una correlación alta y positiva entre días a 50 % de floración y días a 80 % de maduración (0,9; valor p<0,0001), altura de planta y peso de la semilla (0,7; valor p<0,0001), peso de la semilla y porcentage de aceite (0,6; valor p<0,0001), peso de la semilla y número de cápsulas por planta (0,5; P valor <0,0001). Cuando los datos de caracterización se sometieron al método de la varianza se formaron principalmente dos grupos Se intentaron planteamientos DIVA-GIS para el análisis de la diversidad de germoplasma de linaza que fueron mapeados y fueron asignados a rasgos cuantitativos como la altura de planta, el número de cápsulas por planta y contenido de aceite de las semillas.
