大豆事件335-13的表型特征是在2004年至2005年期间在多个环境中进行的，其中大豆事件335-13的油酸含量增加(>；85%)，棕榈酸含量降低(<；5%)。在此条件下，油的新型脂肪酸组成的稳定性不受环境影响。重要的是，新的大豆事件335-13在灌溉和非灌溉生产方案中的产量都没有受到影响。此外，种子的特性，包括总油和蛋白质，以及氨基酸组成，并没有因为脂肪酸组成的大幅变化而改变。这种新颖的石油特征是以一种简单的孟德尔式方式遗传的。335-13事件也被评估为生物柴油的原料。来自Event 335-13的挤压油生产的生物柴油具有改善的冷流和增强的氧化稳定性，这两个关键燃料参数可能会限制这种可再生运输燃料的使用。
Phenotypic characterization of soybean event 335-13, which possesses oil with an increased oleic acid content (> 85%) and reduced palmitic acid content (< 5%), was conducted across multiple environments during 2004 and 2005. Under these conditions, the stability of the novel fatty acid profile of the oil was not influenced by environment. Importantly, the novel soybean event 335-13 was not compromised in yield in both irrigated and non-irrigated production schemes. Moreover, seed characteristics, including total oil and protein, as well as amino acid profile, were not altered as a result of the large shift in the fatty acid profile. The novel oil trait was inherited in a simple Mendelian fashion. The event 335-13 was also evaluated as a feedstock for biodiesel. Extruded oil from event 335-13 produced a biodiesel with improved cold flow and enhanced oxidative stability, two critical fuel parameters that can limit the utility of this renewable transportation fuel.
