Abstract Class-I TCP transcription factors are plant-specific developmental regulators. Inthis study, the role of one such rice gene, OsTCP19, in water-deficit andsalt stress response was explored. Besides a general upregulation by abioticstresses, this transcript was more abundant in tolerant than sensitive ricegenotypes during early hours of stress. Stress, tissue and genotype-dependentretention of a small in-frame intron in this transcript was also observed.Overexpression of OsTCP19 in Arabidopsis caused upregulation ofIAA3, ABI3 and ABI4 and downregulation of LOX2, andled to developmental abnormalities like fewer lateral root formation. Moreover,decrease in water loss and reactive oxygen species and hyperaccumulation of lipiddroplets in the transgenics contributed to better stress tolerance both duringseedling establishment and in mature plants. OsTCP19 was also shown to directlyregulate a rice triacylglycerol biosynthesis gene in transient assays. Genes similarto those up- or downregulated in the transgenics were accordingly found to coexpresspositively and negatively with OsTCP19 in Rice Oligonucleotide ArrayDatabase. Interactions of OsTCP19 with OsABI4 and OsULT1 further suggest itsfunction in modulation of abscisic acid pathways and chromatin structure. Thus,OsTCP19 appears to be an important node in cell signaling whichcrosslinks stress and developmental pathways.

Nitrate (NO3-) plays a pivotal role in stimulating lateral root (LR) formation and growth in plants. However, the role of NO3- in modulating rice LR formation and the signalling pathways involved in this process remain unclear. Phenotypic and genetic analyses of rice were used to explore the role of strigolactones (SLs) and auxin in NO3--modulated LR formation in rice. Compared with ammonium (NH4+), NO3- stimulated LR initiation due to higher short-term root IAA levels. However, this stimulation vanished after 7 d, and the LR density was reduced, in parallel with the auxin levels. Application of the exogenous auxin α-naphthylacetic acid to NH4+-treated rice plants promoted LR initiation to levels similar to those under NO3- at 7 d; conversely, the application of the SL analogue GR24 to NH4+-treated rice inhibited LR initiation to levels similar to those under NO3- supply by reducing the root auxin levels at 14 d. D10 and D14 mutations caused loss of sensitivity of the LR formation response to NO3-. The application of NO3- and GR24 downregulated the transcription of PIN-FORMED 2(PIN2), an auxin efflux carrier in roots. LR number and density in pin2 mutant lines were insensitive to NO3- treatment. These results indicate that NO3- modulates LR formation by affecting the auxin response and transport in rice, with the involvement of SLs.
