“…However, in order to germinate from the deep layer of soil, diverse tissues of different crops' seedling were protruded, such as the mesocotyl in rice and maize, first internode in wheat. A few studies on deep-sowing germination ability have been reported in other plants, such as rice, wheat, barley and oat (Hoshikaw, 1969;Kato et al, 2011;Suge et al, 1998;Takahashi et al, 2008;Turner, Chen, & Bollich, 1982;Wang, Chapman, Bonnett, & Rebetzke, 2009;Zhao et al, 2018), but there were few reports about maize. Zhao et al (2010) found MYBand GA-related genes were involved in deep-sowing tolerance during seed germination by combining Affymetrix Gene Chip and Real time PCR analysis in maize mesocotyl.…”

In arid or semi‐arid regions, deep‐sowing is an effective treasure to ensure seeds absorbing water from deep soil layer at present. However, the existing maize varieties have poor tolerance to deep‐sowing, which is attributed to that few genes are explored and utilised. In this study, 243 IBM Syn4 recombinant inbred lines (RIL) constructed with B73 and Mo17 as parents and 1,339 DNA markers evenly distributed in 10 chromosomes, were used for QTL analysis of deep‐sowing tolerance during seed germination. There were significant differences in germination‐related traits between the parental lines at 12.5 cm sowing depth. Among them, 7, 7, 5, 10 and 2 QTLs for emergence rate, seedling length, plumule length, mesocotyl length and coleoptile length were detected, respectively. These QTLs explained 2.75% to 10.49% of the phenotypic variance with LOD scores ranging from 2.50 to 8.27. In addition, 12 overlapping QTLs formed five QTL clusters on chromosomes 3, 5, 7 and 9. This study provides a basis for molecular marker‐assisted breeding and functional study in deep‐sowing germination of maize.

“…It is necessary to have higher ability of coleorhiza elongation when the testa has strong mechanical resistance to seed germination. Some similar reports have previously described a number of crops, including rice (Hoshikawa 1969, Turner et al 1982, wheat (Suge et al 1998, Rebetzke et al 2007), barley (Takahashi et al 2001), sorghum (Vandelft et al 2000) and maize (Troyer 1997, Zhao et al 2009), about mesocotyl or coleoptile elongation, which is related to the ability of deep-seeding tolerance. Figure S1 shows that the length of coleorhiza was altered throughout the entire process of three-step germination in maize with a tendency of continuous elongation and a final stop.…”

In our present study, using molecular marker technology, we aimed to identify the genetic factors controlling the length of coleorhiza during seed germination based on a population of recombinant inbred lines (RILs) derived from Xinzi517 · B73. The genetic linkage map was constructed with 255 simple sequence repeat markers, which covered 2399 cM of maize genome with an average mapping distance of 9.4 cM. We detected a total of 10 putative quantitative trait loci (QTLs) using composite interval mapping, among which six QTLs were detected on chromosomes 1, 2, 7 and 9 (10°C, 28 day), whereas four QTLs were detected on chromosomes 1, 2, 3 and 9 (25°C, 7 day). The percentage of phenotypic variance (R 2 ) explained by QTL ranged from 5.18 to 16.67 (10°C, 28 day) and 6.73-11.46 (25°C, 7 day), respectively. These results provided the foundation for detecting additional QTL and discovering more favourable alleles for high vigour seed of maize in future study.

“…A local cultivar of wheat, Hong Mang Mai, cultivated in the Loess plateau of China, exhibits an extreme tolerance to deep-seeding conditions due to an extraordinary elongation of the first internode. We previously reported that ethylene stimulated the elongation of the first internode in Hong Mang Mai (Suge et al, 1997a;1998).…”

“…In one local cultivar, Hong Mang Mai, found in the Loess plateau of China, the first internode elongates to emerge from much deeper in the soil than do other cultivars. We previously reported that application of exogenous ethylene stimulated the elongation of the first internode in Hong Mang Mai (Suge et al, 1997a;1998). In addition, we recently found that gibberellin (GA) and potassium play important roles in the tolerance mechanism of wheat seedlings under deep -seeding conditions (Chen et al, 2001).…”
