Abstract Improvement of yield-traits is one of the predominating objectives in wheat breeding. Homeodomain-leucine zipper (HD-ZIP) transcription factor plays significant roles in plant growth and development. The TaHDZ34 (A, B and D sub-genomics) genes consisting of three members of the HD-ZIP IV transcription factor gene subfamily in wheat (Triticum aestivum L.) were cloned. Two haplotypes of TaHDZ34-7A, TaHDZ34-7B or TaHDZ34-7D were respectively identified after the sequence polymorphism analysis, and three functional molecular markers were developed. The TaHDZ34 genes were divided into eight haplotype combinations. Association analysis and distinct population validation jointly indicated that TaHDZ34 had the function of modulating grain number per spike, effective spikelet number per spike, 1,000 kernel weight, and flag leaf area per plant in wheat. Among all haplotype combinations of TaHDZ34, Hap-ABD was the most excellent one. Subcelluar localization showed that TaHDZ34-7A was localized in the nucleus. Interaction proteins of TaHDZ34-7A protein proved to be involved in protein synthesis/degradation, energy production and transportation, and photosynthesis processes. Geographic distribution and frequencies of TaHDZ34 haplotype combinations suggested that the Hap-Abd and Hap-AbD were preferential selection in Chinese wheat breeding programs. The high-yield related haplotype combinations Hap-ABD of TaHDZ34 provided beneficial genetic resources for marker-assisted selection of new wheat cultivars.

Objective: ACTH is frequently produced in non-pituitary tumours, leading to the ectopic-ACTH syndrome, but the molecular mechanisms of its expression remain obscure. This study was aimed at understanding the transcription mechanisms of the ACTH-precursor gene in carcinoid tumours of the lung or thymus. Design: Transcripts coding for a series of corticotroph-associated transcription factor genes were detected, together with markers of the corticotroph phenotype. We studied a series of 41 carcinoid tumours including 15 with proven ectopic-ACTH syndrome. Methods: Specific RT-PCR reactions were designed for each gene including alternatively spliced isoforms. Results: The markers of the corticotroph phenotype were detected in all ACTH-positive tumours. Expression of the Tpit and Pitx1 genes were not restricted to ACTH-positive tumours but were also detected in many ACTH-negative carcinoids. Only a subset of ACTH-negative tumours expressed NAK-1/Nur77, and NeuroD1 expression was detected in <50% of the tumours regardless of their secretory status. The glucocorticoid receptor alpha was detected in every tumour in contrast to its beta isoform detectable in a few tumours only. Chicken ovalbumin upstream promoter-transcription factor 1 (COUP-TF1) and peroxisome proliferator-activated receptor (PPAR) γ2 were expressed in 50% of the tumours of each group whereas PPARγ1 was expressed in almost every tumour. Conclusions: ACTH-positive carcinoids do not share a characteristic expression pattern of the corticotroph-associated transcription factor genes, suggesting that the transcriptional mechanisms of the ACTH-precursor gene differ from those in normal pituitary corticotrophs. Expression of Tpit and Pitx1 genes in most carcinoids suggests that some aspects of the pituitary corticotroph phenotype may belong to general carcinoid differentiation.
