Transcriptome Profiling of Wheat Inflorescence Development from Spikelet Initiation to Floral Patterning Identified Stage-Specific Regulatory Genes.
Early reproductive development in cereals is crucial for final grain number per spike and hence the yield potential of the crop. To date, however, no systematic analyses of gene expression profiles during this important process have been conducted for common wheat (Triticum aestivum). Here, we studied the transcriptome profiles at four stages of early wheat reproductive development, from spikel...
متن کاملWFL, a wheat FLORICAULA/LEAFY ortholog, is associated with spikelet formation as lateral branch of the inflorescence meristem.
FLORICAULA (FLO) of Antirrhinum and LEAFY (LFY) of Arabidopsis encode plant-specific transcription factors, which are necessary and sufficient to specify floral meristem identity. We isolated WFL, a wheat FLO/LFY ortholog, and analyzed its expression pattern. RT-PCR analysis indicated that WFL is expressed predominantly in young spike. The WFL expression pattern during reproductive development ...
متن کاملHeterochronic development of the floret meristem determines grain number per spikelet in diploid, tetraploid and hexaploid wheats.
BACKGROUND AND AIMS The inflorescence of grass species such as wheat, rice and maize consists of a unique reproductive structure called the spikelet, which is comprised of one, a few, or several florets (individual flowers). When reproductive growth is initiated, the inflorescence meristem differentiates a spikelet meristem as a lateral branch; the spikelet meristem then produces a floret meris...
متن کاملFloral transitions in wheat and barley: interactions between photoperiod, abiotic stresses, and nutrient status.
The timing of plant reproduction has a large impact on yield in crop plants. Reproductive development in temperate cereals comprises two major developmental transitions. During spikelet initiation, the identity of the shoot meristem switches from the vegetative to the reproductive stage and spikelet primordia are formed on the apex. Subsequently, floral morphogenesis is initiated, a process str...
متن کاملNomenclature for members of the two-component signaling pathway of plants.
The electronic form of this issue, available as of March 6, 2013, at www.plantphysiol.org, is considered the journal of record. On the Cover: Brachypodium (Brachypodium distachyon), or purple false brome, is a member of the grass subfamily Pooideae, which also includes two of the world’s economically important crop species, wheat (Triticum aestivum) and barley (Hordeum vulgare). This small and ...
