“…Functional studies on ALOG family members have been limited to three model species: Arabidopsis , tomato, and rice (Zhao et al ; Yoshida et al ; Cho and Zambryski ; Li et al ; MacAlister et al ; Yan et al ; Yoshida et al ; Ren et al ; Peng et al ). In rice, the ALOG gene long sterile lemma ( G1 ) is highly expressed in the sterile lemma primordia, and determines the identity of the sterile lemma, which becomes larger, similar to the identity of lemma in the g1 mutant (Yoshida et al ).…”

“…Recently, the Arabidopsis LIGHT‐DEPENDENT SHORT HYPOCOTYL 1 and the Oryza G1 ( ALOG ) gene family have been shown to play an important role in regulating development in eudicots and monocots (Zhao et al ; Yoshida et al ; Cho and Zambryski ; Li et al ; MacAlister et al ; Yan et al ; Yoshida et al ; Ren et al ; Peng et al ). Members of the ALOG family encode short proteins that contain a conserved domain, named the ALOG domain (Yoshida et al ).…”

Legumes can control the number of symbiotic nodules that form on their roots, thus balancing nitrogen assimilation and energy consumption. Two major pathways participate in nodulation: the Nod factor (NF) signaling pathway which involves recognition of rhizobial bacteria by root cells and promotion of nodulation, and the autoregulation of nodulation (AON) pathway which involves long-distance negative feedback between roots and shoots. Although a handful of genes have a clear role in the maintenance of nodule number, additional unknown factors may also be involved in this process. Here, we identify a novel function for a Lotus japonicus ALOG (Arabidopsis LSH1 and Oryza G1) family member, LjALOG1, involved in positively regulating nodulation. LjALOG1 expression increased substantially after inoculation with rhizobia, with high levels of expression in whole nodule primordia and in the base of developing nodules. The ljalog1 mutants, which have an insertion of the LORE1 retroelement in LjALOG1, had significantly fewer nodules compared with wild type, along with increased expression of LjCLE-RS1 (L. japonicus CLE Root Signal 1), which encodes a nodulation suppressor in the AON pathway. In summary, our findings identified a novel factor that participates in controlling nodulation, possibly by suppressing the AON pathway.

“…Although the precise functions of DUF640 domain (or ALOG) proteins have not yet been defined, there are four possible roles for these proteins based on published information, as follows: regulation of inflorescence architecture, determination of organ identity and differentiation, transport of RNA, and sensing of invading DNA. ALOG genes control inflorescence architecture in rice and tomato (Yoshida et al 2009(Yoshida et al , 2013Li et al 2012;MacAlister et al 2012;Yan et al 2013;Teo et al 2014). Arabidopsis genes are expressed at the boundary region of the SAM and lateral organs, indicating their function in organ identity (Cho et al 2011;Takeda et al 2011).…”

“…Although the precise function of the DUF640 motif (or ALOG) is still unclear, the roles of some of these genes have been studied in rice, Arabidopsis and tomato. ALOG genes regulate inflorescence architecture in rice and tomato (Yoshida et al 2009(Yoshida et al , 2013MacAlister et al 2012;Yan et al 2013), while they determine organ boundaries and influence light sensitivity in Arabidopsis (Zhao et al 2004;Cho and Zambryski 2011;Takeda et al 2011).…”

“…Rice LONG STERILE LEMMA (G1), the first identified ALOG gene from monocots, specifies the identity of the sterile lemma by repressing lemma identity via the regulation of downstream target genes (Yoshida et al 2009). Another rice DUF640 domain gene, TRIANGULAR HULL1/BEAK-SHAPED GRAIN 1 (TH1/BSG1), determines grain shape and size by regulating cell division and extension of the lemma and palea (Li et al 2012;Yan et al 2013).

Biotech. 2014 (June) 2(2):126~138 http://dx. ABSTRACTThe functions of DUF640/ALOG (Arabidopsis LSH1 and Oryza G1) domain proteins, which are found in most land plants, have not been well characterized, but some of these proteins regulate inflorescence architecture in rice and specify organ boundaries in Arabidopsis. Arabidopsis DUF640-domain genes are initially identified as LIGHT-SENSITIVE HYPOCOTYLS (LSH) genes. Chinese cabbage leaves have large, white midribs and photosynthetic leaf blades (or lamina). A DUF640 domain gene of Brassica rapa, BrLSH2, is specifically expressed in the midrib of Chinese cabbage. Arabidopsis and rice possess ten LSH family genes, but B. rapa has 24 LSH genes, which can be categorized into two or four groups based on sequence identity. Here, we examined the expression patterns of the LSHs in various Brassica species and analyzed the promoter sequence of the BrLHS2 gene. The transcript levels of most LSH genes were very high in the midrib but low in the leaf blade. These genes were evenly expressed throughout the petiole region of Korean cabbage and highly expressed in the leaf base region near the stem and in the border area in B. oleracea. In addition, BrLSHs were expressed in both bundle and mesophyll cells of the midrib. These expression patterns suggest the possible use of these genes to generate leafy vegetables with altered leaf morphology. The BrLSH2 promoter, which contains auxin-and cytokinin-responsive elements as well as leaf development-related elements, may confer midrib-specific expression, suggesting that this promoter may be useful for the production of midrib-targeted transgenic Chinese cabbage.

The present study involved meta-QTL analysis based on 8,998 QTLs, including 2,852 major QTLs for grain yield (GY) and its following ten component/related traits: (i) grain weight (GWei), (ii) grain morphology related traits (GMRTs), (iii) grain number (GN), (iv) spikes related traits (SRTs), (v) plant height (PH), (vi) tiller number (TN), (vii) harvest index (HI), (viii) biomass yield (BY), (ix) days to heading/ owering and maturity (DTH/F/M) and (x) grain lling duration (GFD). The QTLs used for this study were retrieved from 230 reports involving 190 mapping populations (1999-2020), which also included 19 studies involving durum wheat. As many as 141 meta-QTLs were obtained with an average con dence interval of 1.37 cM (reduced 8.87 fold), the average interval in the original QTL being > 12.15 cM. As many as 63 MQTLs, each based on at least 10 original QTLs were considered to be the most stable and robust with thirteen identi ed as breeder's meta-QTL. Meta-QTLs (MQTLs) were also utilized for identi cation of as many as 1,202 candidate genes (CGs), which also included 18 known genes.Based on a comparative genomics strategy, a total of 50 wheat homologues of 35 rice, barley and maize yield-related genes were also detected in these MQTL regions. Moreover, taking the advantage of synteny, a total of 24 ortho-MQTLs were detected at co-linear regions between wheat with barley, rice and maize. The present study is the most comprehensive till date, and rst of its kind in providing stable and robust MQTLs and ortho-MQTLs, thus providing useful information for future basic studies and for markerassisted breeding for yield and its component traits in wheat.
