Among them, six clones of 19a-1, 19a-3, 19a-5, 19b-4, 20i-2 and 20i-4, were derived from the variety FN95-1702 and seven clones of 16k-1, 16k-3, 16k-5, 16d-1, 16d-2, 16d-4 and 16d-6, were derived from the variety ROC22. A-2 and A-5 were derived from GT 94-119 and the remaining two, B-2 and B-5, were derived from GT96-44. All the above plant materials are provided by the Key Lab of Sugarcane Biology and Genetic Breeding, Ministry of Agriculture, China. The genomic DNA was extracted using the modified CTAB protocol40. Primer design Plasmid 1Ac0229 Plasmid 1Ac0229 which contains the cry1Ac gene was extracted from the transformed Escherichia coli DH5α strain by Plasmid Mini Kit I (Bio-tek Co., Ltd., Beijing, China) and identified by PCR.

Introduction Sugarcane (Saccharum spp.), a major crop of tropical and sub-tropical regions (Henry and Kole, 2010), is the highest yielding crop worldwide and accounts for ~80% of the sugar (sucrose) production in the world (Nayak et al., 2014) and around 92% of that in China (Luo et al., 2012).

Sugarcane can also be used to produce ethanol as an attractive biofuel feedstock in recent years (Henry and Kole, 2010). Sugarcane belongs to the species of vegetative propagation, and most modern sugarcane varieties are only the sexual generations from wild plants, which suggests that sugarcane is of significant potential for further genetic improvement (Henry and Kole, 2010). However, it usually takes more than 10 years for traditional breeders to identify and release a new elite sugarcane variety (Berding and Roach, 1987; D'Hont et al., 1996) from a huge segregated population (Chen et al., 2011).

BMC PLANT BIOLOGY 10/12/18 Foreign cry1Ac gene integration and endogenous borer stress-related genes synergistically improve insect resistance in sugarcane

This method was based on double-standard curves of cry1Ac and CYC/APRT/P4H gene, which were integrated into the multi-target recombined plasmid pG1AcAPC0229 (p1AAPC). We discovered that, for transgene copies estimation in sugarcane, the internal reference genes CYC, APRT, and P4H did not differ significantly, obtaining a high amplification efficiency between 0.95 and 1.05 [2]. The CYC gene was selected for transgene copies estimation and the transgene cry1Ac copies in transgenic sugarcane are shown in Table 1.

The proportions of different transgene cry1Ac copies in transgenic sugarcane are shown in Fig. 1. Further analysis of the cry1Ac gene copies showed that 0–1 copies/2C accounted for 18%, while 1–16 (=16) copies/2C, 17–32 copies/2C, and > 33 copies/2C accounted for 23, 41, and 18%, respectively.

From a BAC library of AP85-441, 35,156 BAC clones were pooled into 712 libraries (mostly of 48 BACs; Supplementary Table 1), and individual BAC pools were sequenced independently by a Hiseq 2500 with PE250 (paired-end model and 250-bp read length), yielding 267.5 Gbp of data that were assembled using three different assemblers: ALLPATHS-LG8, SPAdes9 and SOAPdenovo210, yielding a 2.56-Gbp assembly with contig N50 of 7.4 kb (Supplementary Tables 2 and 3). To reduce fragmentation, 295 Gbp of data from the Pacific Biosciences (PacBio) RS II system (Supplementary Table 4) were used for self-correction and assembly by Canu11, incorporating assembled BAC sequences and correcting and polishing with 90× Illumina paired-end sequences, yielding 3.13 Gbp with contig N50 of 45 kb (Supplementary Table 5).

PHYS_ORG 09/10/18 Success is sweet: Researchers unlock the mysteries of the sugarcane genome

Now, researchers have extracted a sweet scientific prize from sugarcane: its massive and complex genome sequence, which may lead to the development of hardier and more productive cultivars. Producing the comprehensive sequence required a concerted effort by over 100 scientists from 16 institutions; the work took five years and culminated in a publication in Nature Genetics. But the motivation to tackle the project arose long before. "Personally, I waited for 20 years to get this genome sequenced," said Ray Ming, a University of Illinois plant biology professor who instigated and led the sequencing effort.

Abstract Plant-associated fungi are considered a vast source for biotechnological processes whose potential has been poorly explored. The interactions and diversity of sugarcane, one of the most important crops in Brazil, have been rarely studied, mainly concerning fungal communities and their interactions with transgenic plants.

Taking this into consideration, the purpose of this study was, based on culture dependent strategy, to determine the structure and diversity of the fungal community (root endophytes and rhizosphere) associated with two varieties of sugarcane, a non-genetically modified (SP80-1842) variety and its genetically modified counterpart (IMI-1, expressing imazapyr herbicide resistance).

For this, the sugarcane varieties were evaluated in three sampling times (3, 10 and 17 months after planting) under two crop management (weeding and herbicide treatments).

VIETNAMNET 23/01/16 Vietnam denies cultivation of GM sugarcane. VietNamNet Bridge – The Department of Cultivation under the Ministry of Agriculture and Rural Development has rejected news that Vietnam has imported genetically modified (GM) sugarcane for cultivation. The department has written to the Vietnam Sugar and Sugarcane Association (VSSA) dismissing the news after a number of food producers asked the association to make clear whether local sugar mills used GM sugarcane or not. Circular 72/2009/TT-BNNPTNT specifies only GM corn, soybean and cotton have been test-cultivated to evaluate their impact on biodiversity and the environment in the country.

So far, the mass planting of GM corn has been approved. As of the 2013-2014 crop, Vietnam had had over 73 sugarcane varieties with 29 of them chosen by local farmers to grow on 90% of the country’s total cultivation area. Cao Anh Duong, deputy head of the Sugarcane Research Institute, said that 98% of sugarcane varieties planted in Vietnam are imported from different markets. SCIENCES 2.0 04/08/15 Miscanes: Genetically Modified Sugarcane Can Grow Farther North. U.S. farmers have long hoped to extend sugarcane's growing range northward from the Gulf coast because it substantially increase the land available for sugar and (for as long as subsidies last) biofuels. Several hybrid canes developed in the 1980s have proved hardy in cooler climes, surviving overwinter as far north as Booneville, Arkansas, but no one had tested whether the offspring of crosses between sugarcane and a hardy, cold-tolerant grass, Miscanthus - "miscanes" - actually photosynthesize, and thus continue to grow, when the thermometer dips.

Researchers now report that two miscanes perform as well as the grass species Miscanthus x giganteus at 50 degrees Fahrenheit (10 degrees Celsius), staying green and converting carbon dioxide to plant matter at a steady rate. Although the rate of photosynthesis drops at 50 degrees, it doesn't stall out altogether, as it does in sugarcane. Field studies confirmed the laboratory findings. ACTAHORT - 2011 - PROGRESS IN RESEARCH ON GENETICALLY MODIFIED SUGARCANE IN SOUTH AFRICA AND ASSOCIATED REGULATORY REQUIREMENTS. CATCH NEWS 04/05/16 Can GM Sugarcane really make a difference in drought-hit areas?

Will genetically engineered sugarcane be the panacea of drought-hit Karnataka and Maharashtra? The two states are suffering not just from shortage of drinking water, but also from economic losses from cash crops. Sugarcane, in turn, is being blamed for making the drought worse as it is a water-intensive crop. In Maharashtra, while sugarcane occupies under 10% of cultivated area, it guzzles three-fourth of all water used in agriculture. Now there are reports that the Modi government is interested in introducing a sugarcane variety that is genetically altered to grow with less water. This means that farmers won't lose money during drought and can save water too. The environment minister Prakash Javadekar has reportedly written to former agriculture minister Sharad Pawar, that the government intends to encourage field trials of the GM sugarcane developed by Indian Council of Agricultural Research's Sugarcane Breeding Institute, Coimbatore.

ISAAA - Biotechnology for Sugarcane. More than Just a Sugar Crop When we think of sugarcane, right away we associate it with table sugar, the most popular sweetener also chemically known as sucrose. In fact, this grass of the genus Saccharum accounts for 80% of sucrose produced worldwide, with the remaining 20% coming from sugarbeet. Each year around two billion metric tons of sugarcane stalks are crushed in sugar mills to get the sucrose juice. But there is certainly more to this crop than the sweet juice within.
