分枝穗表型是小麦多生小穗的一个重要性状。与每穗显著更多的谷粒产量相关，从而提供更高的潜在产量。然而，小麦分支分生组织（BM）发育的遗传基础仍有待充分阐明。TAW 1是一个ALOG（Arabidopsis LSH 1 and Oryza G1）家族基因，在水稻BM发育中具有独特的调控功能。本研究发现，小麦分枝穗粒层的发育规律与水稻不定粒层的发育规律相似。系统发育分析将ALOG基因分为12组。该基因家族在真双子叶植物和单子叶植物中独立进化，在小麦和水稻之间以及在小麦多倍体化过程中进化保守。此外，实验表明，TtALOG 2 -1A，TAW 1同源基因，在调节不确定BM命运的转变中起着重要作用。最后，大规模RNA测序研究和定量实时聚合酶链反应（qRT-PCR）实验显示，TtALOG的成员可能作用于TtMADS 22，TtMADS 47和TtMADS 55基因的上游，以促进不确定的BM活动。我们的研究结果进一步了解BM在小麦中的发展。
The branched spike phenotype is an important supernumerary spikelet trait of Triticum turgidum L. associated with the production of significantly more grains per spike, thereby offering a higher potential yield. However, the genetic basis of branch meristem (BM) development remains to be fully elucidated in wheat. TAW1, an ALOG (Arabidopsis LSH1 and Oryza G1) family gene, has been shown to function as a unique regulator in promoting BM development in rice. In this study, we found that the development pattern of the BMs of the branched spike in wheat was similar to the indeterminate BMs of rice. Moreover, phylogenetic analysis classified the ALOG genes into 12 groups. This family of genes was found to have evolved independently in eudicots and monocots and was evolutionarily conserved between wheat and rice as well as during wheat polyploidization. Furthermore, experiments revealed that TtALOG2-1A, a TAW1-homologous gene, plays a significant role in regulating the transition of indeterminate BM fate. Finally, large-scale RNA-sequencing studies and quantitative real-time polymerase chain reaction (qRT-PCR) experiments revealed that members of the TtALOGs may act upstream of the TtMADS22, TtMADS47, and TtMADS55 genes to promote indeterminate BM activities. Our findings further knowledge on BM development in wheat.
