Over 50 genes have been targeted for mutations using TALEN in plants, including Arabidopsis, Barley, Brachypodium, maize, tobacco, rice, soybean, tomato and wheat (Table 2). Many of these have been proof-of-concept studies. TALEN scaffolds were optimized for high activity in plants [43]. The optimized TALEN scaffold was then demonstrated by targeted mutagenesis in Arabidopsis [44], tomato [45], Brachypodium [46] and wheat [7]. More recently, TALEN was shown to induce a variety of heritable mutations in rice [47], demonstrating its usefulness in plant genome editing.

As an effective genome editing tool, TALEN has been applied to generate useful traits in crops. In an elegant study, TALEN was used to engineer disease resistance in Xanthomonas oryzae pv. oryzae by destroying the target sequence of TALE effectors in rice [48]. In soybean, the FAD2 gene was targeted for improved oil quality [49]. In wheat, three homologs of MLO were successfully targeted for simultaneous knockout, conferring heritable disease resistance to powdery mildew [7]. Improved rice seeds have been engineered with TALEN, creating traits such as fragrance [50] and storage tolerance [51]. Improved cold storage and processing traits have also been engineered in potato [52].
Due to ease of engineering, CRISPR-Cas9 has been widely adopted for genome editing in plants (Table 3). At the time of this review, CRISPR-Cas9 edited plants include Arabidopsis, barley, Brassica oleracea, cotton, dandelion, flax, lettuce, liverwort, corn, petunia, populus, rice, sorghum, soybean, sweet orange, tomato, wheat, and several tobacco varieties (Table 3). CRISPR-Cas9 quickly moved beyond proof-of-concept; promoting a reverse genetics revolution in plant research and creating many desirable traits in major crops. Using rice as an example, multiple yield-related genes have been targeted in rice [53]. CRISPR-Cas9 has been widely used for functional study on rice genes (Table 3). In addition, environment-induced male sterility has been engineered to facilitate hybrid-based breeding [54, 55]. Disease resistance traits have been developed by knocking out host genes in rice [56] and Arabidopsis [57].
CRISPR-Cas9 is a valuable reverse genetic tool in plant science research. Large chromosomal deletion in Arabidopsis was used to demonstrate redundant functionality of tandem arrayed CBF genes in cold acclimation [63] (Fig. 3d). CRISPR-Cas9 based reverse genetics was even made possible in poplar [64], a woody tree that has traditionally proven difficult for genetic manipulation. Despite challenges with editing polyploidy plants, both hexaploid bread wheat and tetraploid durum wheat were effectively edited by CRISPR-Cas9 [7, 65, 66]. Editing of the tetraploid cotton genome was also recently reported [67, 68]. Camelia sativa is a hexaploid relative to Arabidopsis and editing three copies of the FAD2 gene was demonstrated when screen was carried to T3 generation [69, 70]. Using CRISPR-Cas9, two recent studies disproved conclusions made by earlier work using traditional genetic techniques, further demonstrating that CRISPR-Cas9 is a great addition to existing genetic tools. In one study, knockout alleles of ABP1 were generated in Arabidopsis and it was discovered this gene is not required for auxin signaling or development as originally thought [71]. In another study [72], Rj4 was found to control nodulation specificity in soybean and the identity of this gene confirmed by CRISPR-Cas9 corrected earlier reports.
For all HDR applications, efficiency will need to be improved. Increasing the efficiency of SSN delivery will greatly help genome editing, including HDR applications. If a higher percentage of plants or plant cells can receive SSNs, then more of them will have the potential to undergo HDR without increasing sample size. Although easy to use, agrobacterium-mediated delivery is not as efficient as ballistic bombardment because the latter can introduce multiple copies of donor DNA [93, 98]. One of the potential methods that may solve issues with difficult delivery, as well donor copy number, is geminivirus delivery. In tomatoes, geminiviruses replicons were found to create mutations at a 10-fold higher frequency when compared to agrobacterium mediated transfer [94]. Recently, geminivirus systems were successfully used for CRISPR-Cas9 mediated HDR in rice [99] and wheat [100]. Alternatively, donor DNA may be liberated from integrated chromosome regions with an in-planta gene targeting strategy [86, 101]. The second issue to address is low occurrence of HDR in cells, especially in non-dividing cells. If all cells in culture or in planta were synchronized, then SSN and donor DNA could be introduced during replication which will boost HDR events. Cas9 nickases, with their ability to create single stand breaks (SSBs), have been utilized for HDR in Arabidopsis at high efficiencies and the authors have speculated the mechanism of HDR initiated by SSBs could be different from that of DSBs [85]. The mechanism of SSB based HDR, if discovered, should be useful for enhancing HDR. There are many exciting possibilities for HDR based genome editing, and innovative ideas will continue to further this area.
DNA independent delivery of SSNs for plant genome editing is another trend. Development of such methods are likely motivated for use in crop improvement in regards to regulation [2]. Nucleic-acid free delivery of TALEN has been successfully accomplished [122]. This study demonstrated that delivery of pure nuclease protein into protoplasts was possible albeit at a low frequency [122]. DNA-free delivery of Cas9 was accomplished by incubating Arabidopsis, rice, tobacco, and lettuce protoplasts with Cas9/gRNA ribonucleoprotein complexes [123]. Bread wheat was shown to be amenable to genome editing based on mRNA or ribonucleoprotein delivery of CRISPR-Cas9 [66, 124]. More recently, ribonucleoprotein delivery of CRISPR-Cpf1 was also demonstrated in soybean and wild tobacco protoplasts [120].
In monocots, wheat dwarf virus (WDV) was first engineered for CRISPR/Cas9-based genome editing and gene targeting in wheat (Gil-Humanes et al. 2017). More importantly, this work showed the feasibility of multiplexed gene targeting of multiple homeoalleles of the wheat genome at a 1% frequency. A similar approach using WDV was also applied in rice for targeted insertion of GFP-2A-NPTII to the C terminals of ACT1 and GST genes in a Cas9-overexpressing WT background. The WDV replicon-based tools showed significantly higher targeted knock-in efficiencies than conventional T-DNA tools (Wang et al. 2017).
