“…A recent study showed that NAL2/3 not only regulate distribution of auxin but also provide negative feedback to gibberellin biosynthesis for gibberellin homeostasis in rice. It is indicating that NAL2/3 probably regulate leaf size via the crosstalk of GA and auxin ( Cho and Paek, 2016 ). Rice PLA1 and PLA2 genes act downstream in gibberellin signal transduction pathway and their loss-of-function caused shortening of leaves ( Mimura et al, 2012 ).…”

Yield is majorly affected by photosynthetic efficiency. Leaves are essential structure for photosynthesis and their morphology especially size and shape in a plant canopy can affect the rate of transpiration, carbon fixation and photosynthesis. Leaf rolling and size are considered key agronomic traits in plant architecture that can subsidize yield parameters. In last era, a number of genes controlling leaf morphology have been molecularly characterized. Despite of several findings, our understanding toward molecular mechanism of leaf rolling and size are under-developed. Here, we proposed a model to apprehend the physiological basis of different genes organized in a complex fashion and govern the final phenotype of leaf morphology. According to this leaf rolling is mainly controlled by regulation of bulliform cells by SRL1, ROC5, OsRRK1, SLL2, CLD1, OsZHD1/2, and NRL1, structure and processes of sclerenchyma cells by SLL1 and SRL2, leaf polarity by ADL1, RFS and cuticle formation by CFL1, and CLD1. Many of above mentioned and several other genes interact in a complex manner in order to sustain cellular integrity and homeostasis for optimum leaf rolling. While, leaf size is synchronized by multifarious interaction of PLA1, PLA2, OsGASR1, and OsEXPA8 in cell division, NAL1, NAL9, NRL1, NRL2 in regulation of number of veins, OsCOW1, OsPIN1, OsARF19, OsOFP2, D1 and GID in regulation of phytohormones and HDT702 in epigenetic aspects. In this review, we curtailed recent advances engrossing regulation and functions of those genes that directly or indirectly can distress leaf rolling or size by encoding different types of proteins and genic expression. Moreover, this effort could be used further to develop comprehensive learning and directing our molecular breeding of rice.

“…Ectopic expression of STENOFOLIA (STF) in three monocot species, i.e., switchgrass, Brachypodium distachyon and rice improves the biomass yield, and STF directly binds to several regions in the promoters of cytokinin oxidase/dehydrogenase genes and represses their transcription allowing accumulation of active cytokinin pools, leading to more leaf blade lateral outgrowth [ 26 ]. OsWOX3A is reported to participate in root development by modulating GA-auxin crosstalk [ 27 ]. These results suggest the regulation of WOX transcription factor in leaf expansion is involved with auxin, cytokinin and gibberellin.…”

The WOX (WUSCHEL-related homeobox) is a plant-specific transcription factor involved in plant development and stress response. However, few studies have been reported on the WOX gene in woody plants. In this study, 10 BpWOX genes were isolated from paper mulberry by RACE-PCR and categorized into three clades through phylogenetic analysis, ancient, intermediate and WUS clade. Among them, five members had the transcriptional activity detected by yeast one-hybrid and seven were uniquely localized to the nucleus through green fluorescent protein (GFP) observation. The expression patterns of BpWOX genes in different tissues and under diverse treatments were quantified by the qRT-PCR method. Results showed that BpWUS was expressed in the apical bud, stem and root, BpWOX5 and BpWOX7 functioned only in the root tip, and three BpWOXs regulated leaf development redundantly. BpWOX9 and BpWOX10 were induced by indole-3-acetic acid (IAA) or jasmonic acid (JA), while BpWOX2 was repressed by five phytohormones. Interestingly, most BpWOX genes were responsive to the abiotic stress stimuli of drought, salt, cold, and cadmium (CdCl2). Together, our study revealed that BpWOXs were functionally divergent during paper mulberry development and environmental adaptation, which might be related to their evolutionary relationships. Our work will benefit the systematic understanding of the precise function of WOX in plant development and environmental stress responses.

“…OsWOX3A gene has been found to regulate both lateral root development (Cho et al 2016) and root hair elongation (Yoo et al 2013). Rice oswox3a mutants had increased root hair length, but grew shorter and fewer lateral roots compared to wild-type (Yoo et al 2013).…”

To meet the demands of a rising human population, plant breeders will need to develop improved crop varieties that maximize yield in the face of increasing pressure on crop production. Historically, the optimization of crop root architecture has represented a challenging breeding target due to the inaccessibility of the root systems. Root hairs, single cell projections from the root epidermis, are perhaps the most overlooked component of root architecture traits. Root hairs play a central role in facilitating water, nutrient uptake, and soil cohesion. Current root hair architectures may be sub-optimal under future agricultural production regimes, coupled with an increasingly variable climate. Here, we review the genetic control of root hair development in the world's three most important crops: rice, maize and wheat, and highlight conservation of gene function between monocots and the model dicot species Arabidopsis. Advances in genomic techniques including Gene-Editing combined with traditional plant breeding methods have the potential to overcome many inherent issues associated with the design of improved root hair architectures. Ultimately, this will enable detailed characterization of the effects of contrasting root hair morphology strategies on crop yield and resilience, and the development of new varieties better adapted to deliver future food security.
