“…All these four candidate genes were annotated as (leucine-rich repeat receptorlike kinase, LRK). LRK1, which includes the protein kinaselike domain (IPR011009), protein kinase domain (IPR000719), serine/threonine/dual specificity protein kinase, catalytic domain (IPR002290), which restricts gibberellin biosynthesis during the internode elongation process by down-regulation of the gibberellin biosynthetic gene coding for ent-kaurene oxidase, could influence the yield of rice [32].…”

In this study, 147 recombinant inbred soybean lines constructed from the parents Charleston and Dongnong594, were used to map quantitative trait loci (QTLs) for seed weight per plant in multiple years (2006 to 2010 and 2013). QTL mapping was done using a simple sequence repeat (SSR) map combined with specific-locus amplified fragment (SLAF) map and the composite interval mapping (CIM), multiple interval mapping (MIM) and inclusive complete interval mapping method (ICIM) algorithms. By combining QTLs with the QTL physical locations, two QTL intervals located in the D1a and C2 linkage groups were found in different years. KEGG and GO annotations of the 413 genes located within these QTL intervals were used to screen for candidate genes potentially involved in seed production. Based on WeGo online genetic classification, we ultimately selected four genes related to yield traits, Glyma.01G158700, Glyma.01G156800, Glyma.01G125400 and Glyma.01G147800, as candidate genes.

“…The comparison indicated that 56 QTLs tagged by 35 associated markers were colocalized with 11 mapped QTLs and 19 characterized genes. Among the colocalized loci, 19 known functional genes were D2 (Hong et al, 2003), SUI3 (Yin et al, 2013), and OsBRI1 (Yamamuro et al, 2000) on chromosome 1; LRK1 (Yang et al, 2013) and GID2 (Sasaki et al, 2003) on chromosome 2; D14 (Arite et al, 2009), SSD1 (Asano et al, 2010), OsSIN (Han et al, 2005), and OsPIL1 (Todaka et al, 2012) on chromosome 3; OsCCD7 (Zou et al, 2005) on chromosome 4; GID1 (Ueguchi‐Tanaka et al, 2005) and SUI2 (Yin et al, 2013) on chromosome 5; D3 (Ishikawa et al, 2005), OsMAPK6 (Liu et al, 2015), and D35 (Itoh et al, 2004) on chromosome 6; OSH15 (Sato et al, 1999) on chromosome 7; OsSPY (Shimada et al, 2006) on chromosome 8; and ACO1 (Iwamoto et al, 2010) and OsEATB (Qi et al, 2011) on chromosome 9 (Table 2, Supplemental Files 8 and 9).…”

“…In the eui1 and eui2 mutants, the cell lengths in the uppermost internode were significantly longer than that of the wild‐type and thus gave rise to the elongated uppermost internode (Yang et al, 2002; Luo et al, 2006). OsEATB and LRK1 inhibit elongation of every internode in rice (Qi et al, 2011; Yang et al, 2013). A dominant gene, Ssi1 , controlled the semidwarfism by inhibiting SIL (Miura et al, 2009).…”

Culm length (CL) is composed of different elongated internode lengths (EILs) and is closely correlated to the lodging resistance in rice (Oryza sativa L.). The objective of this study was to identify quantitative trait loci (QTLs) stably associated with CL and the first to fourth EIL from panicle base, which were abbreviated as FIL (first), SIL (second), TIL (third), and FOIL (fourth) in japonica rice, respectively. Association mapping was conducted using the genotypes determined by 154 simple sequence repeat markers and the phenotypes in 2010, 2011, and 2015 of 331 japonica rice accessions. The study mapped 6, 5, 15, 2, and 2 QTLs tagged by 22 markers on eight chromosomes and stably associated with CL, FIL, SIL, TIL, and FOIL, respectively. Five QTLs, qCL‐6‐2, qFIL‐6‐5, qSIL‐6‐2, qTIL‐6‐3, and qFOIL‐7‐5, explained the largest phenotypic variance of CL, FIL, SIL, TIL, and FOIL, respectively. RM1340, RM1374, RM281, RM233, and RM225 were stably and specifically associated with CL, FIL, SIL, TIL, and FOIL, respectively. Forty‐three effective alleles were identified. Four and three donors with negative and positive alleles were recommended. There was a highly significant phenotypic difference between accessions with or without effective alleles. These QTLs, associated markers, effective alleles, and their donors could be used to improve CL and specific EIL in japonica rice.

“…Therefore, new techniques have been developed to improve brahmi production. One of the most popular techniques is elicitation with elicitors (physical agent, biological or chemical substances) treatments (Sharma et al, 2013) to increase bacoside content. However, since there are few reports concerning biosynthetic pathways in brahmi, the effects and functions of elicitation are difficult to predict.…”

Bacopa monnieri is a medicinal herb that is increasing in demand in Thailand. However, the lack of high-bacoside cultivars has limited pharmaceutical utilization and production. Here, chromosome doubling in B. monnieri was attempt to improve biomass and bacoside content in its seedling. Nodal segments were treated with colchicine (0, 0.025, 0.05, 0.075, 0.1, and 0.5% w/v) for 24 or 48 h before transferring to multiple shoot induction medium (1/2 MS medium supplemented with 0.2 mg L−1 BAP). Of 326 tested clones, 18 and 84 were mixoploids and autotetraploids, respectively. The highest autotetraploid-induction percentage (14.6%) was found after treated with 0.5% (w/v) colchicine, and 48 hours exposure. From 28 selected autotetraploid clones, 21 and 13 have significantly higher fresh and dry weight compared to the diploid clone, respectively. The maximum fresh and dry weight of autotetraploid plants was 2.8 and 2.0-time higher than diploid plants, respectively. Moreover, the maximum total bacoside content (1.55 mg plant−1) was obtained from an autotetraploid plant, which was 2.3-fold higher than the level in diploid plants. These novel autotetraploids have the potential to be developed as resources for value-added improvements in the medicinal and pharmaceutical industries.
