Located in chromosome 1HL (25); eam8.k is about 11.4 cM distal from the trd1 (third outer glume 1) locus and 20.9 cM distal from the Blp1 (Black lemma and pericarp 1) locus (25, 29); eam8.w is associated with SNP markers 2_0603 to 2_0138 (positions 199.04 to 202.26 cM) in 1H in bin 14 of the Bowman backcross-derived line BW290 (3); eam8.k is associated with SNP markers 1_0782 to 1_0443 (positions 193.83 to 206.12) in 1H bin 14 of the Bowman backcross-derived line BW289 (5); ert-o.16 is associated with SNP markers 1_0911 to 1_1509 (positions 177.51 to 199.04) in1H bins 13 to 14 of the Bowman backcross-derived line BW319 (5), in 1H bin 14.

Description:

Early heading early maturity 8 (eam8) is associated with decreased culm length, spike length, kernels per spike, and grain yield (20, 29, 31). Mutant plants are day-length neutral or photoperiod insensitive when grown in the fall at Kurashiki, Japan. They head about 20 days earlier than the standard mid-season cultivar, Akashinriki (31). Day-length neutrality was observed in early heading mutants isolated from spring barley in Sweden (4, 13). Under controlled environmental conditions, number of days to heading did not change as photoperiod is altered (4, 14). All mat-a induced mutants were characterized by yellowish-green seedlings at an early stage of development under controlled environmental conditions (3). Other eam8 mutants showed a similar response by becoming yellow green under specific growing conditions, 8 to 12 hours of illumination at low temperatures (below 10C) plus high temperature (20C or higher) during the dark period (9, 25, 29). The color change is caused by photothermal stress, which increases the zeaxanthin content at the expense of chlorophyll and other pigments (9, 23, 29). The mutant stock mat-a.8 was released as the cultivar Mari Mari (NGB 14656, NGB 1491, PI 428407) (13, 15). When grown under 12 h days, the levels of phytochrome B (phyB) decreased in light-grown BMDR-1 plants, containing a mutant allele at the eam8 locus, compared to normal plants (16). The instability in phyB content was reported to be responsible for photoperiod insensitivity of eam8 mutants (16). Under continuous light and with far-red light treatment for seven days, most differences in heading date between BMDR-1 and BMDR-8 (Shabet) are eliminated (23). The selection of independent eam8 mutations facilitated short growth-season adaptation and expansion of the geographic range of barley (6). When the eam8.k gene was placed in a winter barley genetic background [controlled by the sgh1.a (spring growth habit 1 or HvVrn2) gene], the vernalization requirement sgh1 (Vrn2) was expressed under all photoperiods and the early flowering phenotype was partially repressed in unvernalized plants (27).The Mat-a or Eam8 (HvELF3) locus has been cloned and is a homolog of the Arabidopsis thaliana circadian clock regulator Early Flowering 3 (ELF3) (6, 32). Among 87 mat-a alleles identified more than 20 different mat-a alleles had mutations leading to the defective putative ELF3 protein (32). The eam8 mutants have increased expression of the floral activator HvFT1 (Sgh3,, Vrn3). which is independent of allelic variation at Eam1 (Ppd-H1) locus (6). Early flowering of the mat-a (elf3) mutants lail to block excess gibberellin (GA) synthesis and expression of HvFT1 (2). Alvarez et al. reported that EARLY FLOWERING3 (ELF3) is a candidate gene for the earliness per se locus Eps-Am1 in Triticum monococcum (1).
