“…It reduces insecticide usage by 24%, increases yield up to 150% and leads to increased farmer income ( Carpenter, 2010 ; Kathage and Qaim, 2012 ). Similar economic impact and acceptance is seen worldwide for Bt rice ( Li et al, 2016 ), Bt corn ( Edgerton et al, 2012 ) and Bt sugarcane ( Ye et al, 2016 ).…”

Bt Jute Expressing Fused δ-Endotoxin Cry1Ab/Ac for Resistance to Lepidopteran Pests

et al. 2018

Jute (Corchorus sp.) is naturally occurring, biodegradable, lignocellulosic-long, silky, golden shiny fiber producing plant that has great demands globally. Paper and textile industries are interested in jute because of the easy availability, non-toxicity and high yield of cellulosic biomass produced per acre in cultivation. Jute is the major and most industrially used bast fiber-producing crop in the world and it needs protection from insect pest infestation that decreases its yield and quality. Single locus integration of the synthetically fused cry1Ab/Ac gene of Bacillus thuringiensis (Bt) in Corchorus capsularis (JRC 321) by Agrobacterium tumefaciens-mediated shoot tip transformation provided 5 potent Bt jute lines BT1, BT2, BT4, BT7 and BT8. These lines consistently expressed the Cry1Ab/Ac endotoxin ranging from 0.16 to 0.35 ng/mg of leaf, in the following generations (analyzed upto T4). The effect of Cry1Ab/Ac endotoxin was studied against 3 major Lepidopteran pests of jute- semilooper (Anomis sabulifera Guenee), hairy caterpillar (Spilarctia obliqua Walker) and indigo caterpillar (Spodoptera exigua Hubner) by detached leaf and whole plant insect bioassay on greenhouse-grown transgenic plants. Results confirm that larvae feeding on transgenic plants had lower food consumption, body size, body weight and dry weight of excreta compared to non-transgenic controls. Insect mortality range among transgenic feeders was 66–100% for semilooper and hairy caterpillar and 87.50% for indigo caterpillar. Apart from insect resistance, the transgenic plants were at par with control plants in terms of agronomic parameters and fiber quality. Hence, these Bt jutes in the field would survive Lepidopteran pest infestation, minimize harmful pesticide usage and yield good quality fiber.

“…To date, a number of transgenic sugarcane transformed with genes expressing sugar improvement ( Chong et al, 2007 ; Wu and Birch, 2007 ), herbicide resistance ( Gallo-Meagher and Irvine, 1996 ; Manickavasagam et al, 2004 ), insect resistance to sugarcane stem borer ( Diatraea saccharalis F.; Arencibia et al, 1997 ; Weng et al, 2006 ; Gao et al, 2016 ) and wooly aphid ( Ceratovacuna lanigera Z.; Zhangsun et al, 2008 ), disease resistance to Sugarcane mosaic virus (SCMV; Gilbert et al, 2005 ) and Xanthomonas albilineans ( Zhang et al, 1999 ), abiotic stress tolerance to drought ( Zhang et al, 2006 ; Molinaria et al, 2007 ), and recombination protein of ER-targeted human cytokine protein GM-CSF ( Wang et al, 2005 ) and aromatic hydroxybenzoic acid (pHBA; Petrasovits et al, 2007 ) have been successfully developed. Although traits of interest are being tested in various sugarcane cultivated countries, no commercial transgenic sugarcane line has been reported ( Cheavegatti-Gianotto et al, 2011 ; Dal-Bianco et al, 2012 ; Ye et al, 2016 ), except for three drought-tolerant sugarcane transgenic events, NXI-1T, NXI-4T, and NXI-6T, which have been approved in Indonesia 8 but without commercial cultivation.…”

Beta-1,3-glucanases (EC 3.2.1.39), commonly known as pathogenesis-related (PR) proteins, play an important role not only in plant defense against fungal pathogens but also in plant physiological and developmental processes. However, only a limited number of sugarcane beta-1,3-glucanase genes have been isolated. In the present study, we identified and characterized a new beta-1,3-glucanase gene ScGluD2 (GenBank Acc No. KF664181) from sugarcane. An X8 domain was present at the C terminal region of ScGluD2, suggesting beta-1,3-glucan-binding function. Phylogenetic analysis showed that the predicted ScGluD2 protein was classified into subfamily D beta-1,3-glucanase. Localization of the ScGluD2 protein in the plasma membrane was determined by tagging it with green fluorescent protein. The expression of ScGluD2 was more up-regulated in sugarcane smut-resistant cultivars in the early stage (1 or 3 days) than in the susceptible ones after being challenged by the smut pathogen, revealing that ScGluD2 may be involved in defense against the invasion of Sporisorium scitamineum. Transient overexpression of ScGluD2 in Nicotiana benthamiana leaves induced a defense response and exhibited antimicrobial action on the tobacco pathogens Pseudomonas solanacearum and Botrytis cinerea, further demonstrating that ScGluD2 was related to the resistance to plant pathogens. However, the transcripts of ScGluD2 partially increased (12 h) under NaCl stress, and were steadily up-regulated from 6 to 24 h upon ABA, H2O2, and CdCl2 treatments, suggesting that ABA may be a signal molecule regulating oxidative stress and play a role in the salt and heavy metal stress-induced stimulation of ScGluD2 transcripts. Taken together, ScGluD2, a novel member of subfamily D beta-1,3-glucanase, was a stress-related gene of sugarcane involved in plant defense against smut pathogen attack and salt and heavy metal stresses.

“…Guangxi Province had been ranking the first in sugarcane planting area, cane and sugar production, and economic benefit in China (Ye et al, 2016;Li, 2010). With tall plant and large biomass above ground, at the late elongation and maturation stages after October, the plant height of sugarcane exceeds 300 cm, the higher the plant is, the greater the risk of lodging meets (Li et al, 2018a).…”

Sugarcane is the largest sugar crop in China and the world, and one of the important commercial crops in southern China. However, the influence of sugarcane lodging is more and more serious with increasing cane yield. After lodging, the plant growth and sugar accumulation in stalk was seriously affected, resulting in considerable losses in cane and sugar yield, and difficulty in machine operation in the field. At present, there is no perfect evaluation method for sugarcane lodging, and little has been done on research of related physiological and biochemical indexes, microscopic structures and so on although there have been some reports on the effects of sugarcane lodging. But there has been a lot of research on lodging in rice, corn and wheat, which could be referred for studying the resistance mechanism and evaluation method in sugarcane.
