Plant WRKY transcription factors （TFs） constitute one of the largest families of proteinsinvolved in biotic and abiotic stress responses. These TFs have a conserved 60 amino acid WRKYdomain at the n-terminal and a zinc finger motif at the C-terminal. To examine the relevance ofOsWRKY72 in imparting salinity stress tolerance, two indica rice genotypes, Rasi （tolerant genotype）and Tellahamsa （susceptible genotype）, were used. In Rasi seedlings at 12 h under 100 mmol/L naClstress, OsWRKY72 expression was up-regulated, whereas in Tellahamsa, it was highly up-regulated atlethal stress. Full-length OsWRKY72 cDnA was cloned from these two rice genotypes for furtheranalysis. We identified a variant, termed as OsWRKY72b that carries an additional sequence of 111 bpwithin the WRKY domain. Expression of OsWRKY72b was higher under salinity stress in Rasi than inTellahamsa. Disorder prediction of OsWRKY72b showed that the additional sequence in the WRKYdomain is ordered thereby maintaining the tertiary structure that might interact with the major groove ofDnA. Prediction of phosphorylation sites in OsWRKY72b indicated that a few serine residues could bethe potential phosphorylation sites. In this study, we firstly reported a OsWRKY72 variant that couldhave a role in abiotic stress responses.

An Efficient Protocol for Total RnA Isolation from Healthy and Stressed Tissues of Mulberry (Morussp.) and Other Species

American Journal of Plant Sciences 2014年第13期5卷 2057-2065页

Extraction of quality RnA for molecular biology applications from perennial woody plants like mulberry is complicated due to the presence of high polysaccharides, polyphenols and other secondary metabolites. Since the existing methods failed to yield quality RnA in sufficient quantity from leaf and root tissues of mulberry, in this study, we modified the CTAB-based protocol. The standardised protocol yielded high quantity (520.00 μg/g fresh weight of leaf tissue) of quality RnA and the RnA extracted was suitable for all downstream applications such as cDnA synthesis, PCR and whole transcriptome analysis. The method developed was also found to be useful for isolating good quality and quantity total RnA from desiccated and salinity stressed leaf tissues of mulberry. The protocol was also applied successfully to isolate total RnA from leaf tissues of other species such as cardamom, papaya and rice.

Standardization of DnA Extraction Method from Mature Dried Leaves and ISSR-PCR Conditions for Melia dubia Cav. —A Fast Growing Multipurpose Tree Species

引用

American Journal of Plant Sciences 2016年第3期7卷 437-445页

作者： Swati Rawat Geeta Joshi D. Annapurna A. n. Arunkumar nataraja n. karaba Tree Improvement and Genetics Division Institute of Wood Science and Technology Bengaluru India Department of Crop Physiology University of Agricultural Sciences GKVK Bengaluru India

Melia dubia Cav. of family Meliaceae is a fast growing, high value tree species native to India. Isolating DnA from matured dried leaves of M. dubia was difficult due to accumulation of secondary metabolites, majorly polyphenolics, which resulted in dark brown to black colour of the pellet. In this study, a modified STE-(Sucrose, Tris-HCl and Ethylene Diamine Tetra Acetic Acid) CTAB (hexadecyltrimethylammonium bromide) method was standardized for removal of polyphenolics. The protocol developed yielded 200 - 1000 ng/μl of quality DnA without any impurities as evident by A260/280 ratio ranging from 1.75 - 2.0. It was also suitable for extracting quality DnA from other members of Meliaceae like Azadirachta indica and Melia azedarach. In downstream applications, the extracted DnA was used for PCR amplification by using ISSR and SSR markers. ISSR PCR conditions were optimized in a reaction volume of 25 μl, consisting of 30 ng of template DnA, 1.5 mM MgCl2, 200 μM of each of dnTPs and 2 U of Taq polymerase. The best amplification was observed and the same was applicable for SSR markers.

In VitroPlant Regeneration of Morus indicaL. cv. V1 Using Leaf Explant

引用

American Journal of Plant Sciences 2013年第10期4卷 2001-2005页

作者： Melur Kodandaram Raghunath karaba n. nataraja Jyothi Sainath Meghana Radha Sivarajan Sajeevan Mala V. Rajan Syed Mashayak Hussaine Qadri Central Sericultural Research and Training Institute Srirampura Mysore India Department of Crop Physiology University of Agricultural Sciences GKVK Bangalore India.

Adventitious bud induction and plantlet regeneration were studied in a popular mulberry variety, V1 using leaf as an explant. Fully expanded leaf explants were cultured on Murashige and Skoog’s (MS) medium supplemented with thidiazuron (TDZ) (0.5-4.0 mg/l), 6-benzylaminopurine (BAP) (0.5-2.0 mg/l), indole acetic acid (IAA) (2.0 mg/l), gibberlic acid (GA3) (1.0-2.0 mg/l) silver nitrate (AgnO3) (2.0 mg/l) and different carbon sources such as sucrose, fructose and glucose (10%-30%) either individually or in combination to induce adventitious buds and regeneration. The highest percentage (63%) of adventitious bud formation and regeneration (68%) was achieved in the medium containing MS with TDZ (1.0 mg/l), IAA (2.0 mg/l) and AgnO3 (2.0 mg/l). For subsequent regeneration and shoot elongation the MS medium having BAP (1.0 mg/l), GA3 (2.0 mg/l) and AgnO3 (2.0 mg/l) was found to be suitable. Amongst the carbon sources tested, the most suitable carbon source was found to be sucrose (3%) followed by fructose (2%) for adventitious bud formation. Excised in vitro shoots were rooted (60%-80%) in half strength MS medium supplemented with indole-3-butyric acid (1.0 mg/l). The well rooted plantlets were hardened in soil + sand + farm yard manure (FYM) mixture with a success rate of 70%-90%. Since in vitro regeneration is highly genotype-dependent in mulberry, the standardized protocol can be effectively used for further improvement of this leading genotype using biotechnological approaches.
