“…The Puroindoline D1 genes have a dramatic impact on kernel texture, a significant effect on processing quality and may play a role in plant disease defense (Chen et al 2007;Feiz et al 2009;Morris 1997, 1998;Lillemo and Morris 2000;Ma et al 2009;Zhang et al 2010Zhang et al , 2011 Morris et al 2001;Xia et al 2005). In this study, we analyzed the frequency of PinaD1b and Pinb-D1b among four hard wheat groups (hard red winter, hard white winter, hard red spring and hard white spring), and found that 94 of 101 hard winter wheats (red and white) carried Pina-D1b (Table 3).…”

Kernel texture is a major factor influencing the classification and end use properties of wheat (Triticum aestivum L.), and is mainly controlled by the Puroindoline a (Pina) and Puroindoline b (Pinb) genes. Recently, a new puroindoline gene, Puroindoline b-2 (Pin b-2), was identified. In this study, 388 wheat cultivars and advanced breeding lines from the U.S. Pacific Northwest were investigated for frequencies of Puroindoline D1 alleles and Pinb-2 variants 2 and 3. Results indicated that Pinb-D1b (74.0%) was the predominant genotype among hard wheats (N = 196), the only other hard allele encountered was Pina-D1b (26.0%). Across all varieties, Pinb-2v3 was the predominant genotype (84.5%) compared with Pinb-2v2 (15.5%). However, among 240 winter wheat varieties (124 soft white, 15 club, 68 hard red and 33 hard white varieties), all carried Pinb-2v3. Among spring wheats, Pinb-2v2 and Pinb-2v3 frequencies were more variable (soft white 25.0:75.0, hard red 58.2:41.8 and hard white 40.0:60.0, respectively). Kernel texture variation was analyzed using 247 of the 388 wheat varieties grown in multi-location factorial trials in up to 7 crop years. The range of variety means among the four groups, soft winter, soft spring, hard winter and hard spring, was on the order of 15-25 single kernel characterization system (SKCS) Hardness Index. The least significant difference for each of these trials ranged from 2.8 to 5.6 SKCS Hardness Index. Observations lead to the conclusion that Pinb-2 variants do not exert a prominent effect on kernel texture, however, Pinb-2 variants do identify features of wheat germ plasm structure in the U.S. Pacific Northwest.

“…An additional effect was reported by Zhang et al (2010) who found that constitutive expression of the puroindolines in corn increased embryo size and total seed oil content. The mechanism of embryo size increases in corn or of polar lipid content in wheat is not clear but both may result directly from the affinity of puroindolines for lipids (Dubreil et al, 1997;Feiz et al, 2009b).…”

B iodiesel is a low-carbon-intensity renewable fuel with up to 99% lower greenhouse gas emissions than petroleum-based diesel. The use of oil crops for biodiesel is under critical examination. It is expensive and suffers from the food versus fuel risk/benefi t problem. Consequently, many countries (e.g. Malaysia and countries in the EU) are scaling back the use of oil crops as feedstock for biofuel production. The limitations of these traditional crops are leading the renewable fuels industry to consider innovative, sustainable, and profi table biomass-based platforms. Plant genetic engineering and other new breeding technologies are essential for developing such biomass-based platforms because they enhance plant tolerance to abiotic and biotic stresses, resulting in higher feedstock yields, greater net energy gain, and the generation of high-value co-products. We review and summarize the recent improvements of oil crops through plant genetic engineering that may increase widespread and cost-effective production of biodiesel and value-added co-products for green chemistry applications.
