Project description:To investigate how OsGATA6 regulates heading date, grain number per panicle, and grain phenotypes, we collected panicle primordia of ZH11 and OsGATA6-AM lines at the In2 and In3 stages. We analyzed gene expression using a rice expression profiling chip. Compared with ZH11, OsGATA6-AM lines had 818 up-regulated genes and 284 down-regulated genes

Project description:The precise regulation of flowering time, known as heading date in rice (Oryza sativa L.), is critical for regional adaptation, agricultural productivity, and crop rotation practices. In rice, the florigen activation complex (FAC) and its downstream effectors are well-characterized mediators of the floral transition in the shoot apical meristem (SAM). Here, we characterized OsMYB110 as a SAM-localized transcription factor that promotes flowering, exhibiting functional similarity to the established flowering regulator Nhd1 (N-mediated heading date-1). Through integrated molecular and genetic analyses, we demonstrate that: (1) Nhd1 directly binds to the OsMYB110 promoter to activate its expression, while OsMYB110 in turn binds to and activates the OsMADS15 promoter to control flowering progression, and (2) genetic epistasis places OsMYB110 downstream of Nhd1 but upstream of OsMADS15 in the flowering regulation hierarchy. Furthermore, while elevated phosphate accelerates flowering, this response is abolished in myb110 and mads15 mutants but maintained in nhd1 mutants. These results define a previously unrecognized Nhd1–OsMYB110–OsMADS15 regulatory module that integrates developmental and nutrient signaling pathways to control rice flowering time.

Project description:HEADING DATE 1 (Hd1) is a zinc finger transcription factor, central in the photoperiodic flowering network. Hd1 operates as a repressor of flowering under long days but reverts to a promoter of flowering under short days. How this dual function is organized at the proteomic level is still unknown. Here, we have used MS to interrogate the proteome of hd1 mutants and wild type plants under long and short day conditions, and we identified differential abundance of proteins involved in cell wall metabolism.

Project description:Plants show a high degree of developmental plasticity in response to external cues, including day length and environmental stress. Water scarcity in particular can interfere with photoperiodic flowering, resulting in the acceleration of the switch to reproductive growth in several species, a process called drought escape. However, other strategies are possible and drought stress can also delay flowering, albeit the underlying mechanisms have never been addressed at the molecular level. We investigated these interactions in rice, a short day species in which drought stress delays flowering. A protocol that allows the synchronization of drought with the floral transition was set up to profile the transcriptome of leaves subjected to stress under distinct photoperiods. We identified clusters of genes that responded to drought differently depending on day length. Exposure to drought stress under floral-inductive photoperiods strongly reduced transcription of EARLY HEADING DATE 1 (Ehd1), HEADING DATE 3a (Hd3a) and RICE FLOWERING LOCUS T 1 (RFT1), primary integrators of day length signals, providing a molecular connection between stress and the photoperiodic pathway. However, phenotypic and transcriptional analyses suggested that OsGIGANTEA (OsGI) does not integrate drought and photoperiodic signals as in Arabidopsis, highlighting molecular differences between between long and short day model species.
