“…8,9 Our recent results revealed that HO is involved in nitric oxide and auxin-induced LR formation in rice. 10 We also provided indirect evidence to show that CO increases HO activity in rice. 10 However, it is not known whether BV, another product of HO catalyzed reaction, promotes LR formation in rice.…”

In this study, we examined the effect of biliverdin (BV), a product of heme oxygenase (HO) catalyzed reaction, on lateral root (LR) formation in rice. Treatment with BV induced LR formation and HO activity. As well, BV, could induce OsHO1 mRNA expression. Zn protoporphyrin IX (the specific inhibitor of HO) reduced LR number, HO activity and OsHO1 mRNA level induced by BV. Our data suggest that HO is required for BV-induced LR formation in rice.

“…The HEME OXYGENASE 1 ( HOX1 ) gene controls the formation of lateral roots via the production of carbon monoxide. HOX1 is regulated by auxin and stress related signals, such as jasmonate and nitric oxide (Chen et al [ 2012 ]; Hsu et al [ 2012 ]), which suggests that this pathway can contribute to the modulation of root architecture in response to stress.…”

In this review, we report on the recent developments made using both genetics and functional genomics approaches in the discovery of genes controlling root development in rice. QTL detection in classical biparental mapping populations initially enabled the identification of a very large number of large chromosomal segments carrying root genes. Two segments with large effects have been positionally cloned, allowing the identification of two major genes. One of these genes conferred a tolerance to low phosphate content in soil, while the other conferred a tolerance to drought by controlling root gravitropism, resulting in root system expansion deep in the soil. Findings based on the higher-resolution QTL detection offered by the development of association mapping are discussed. In parallel with genetics approaches, efforts have been made to screen mutant libraries for lines presenting alterations in root development, allowing for the identification of several genes that control different steps of root development, such as crown root and lateral root initiation and emergence, meristem patterning, and the control of root growth. Some of these genes are closely phylogenetically related to Arabidopsis genes involved in the control of lateral root initiation. This close relationship stresses the conservation among plant species of an auxin responsive core gene regulatory network involved in the control of post-embryonic root initiation. In addition, we report on several genetic regulatory pathways that have been described only in rice. The complementarities and the expected convergence of the direct and reverse genetic approaches used to decipher the genetic determinants of root development in rice are discussed in regards to the high diversity characterizing this species and to the adaptations of rice root system architecture to different edaphic environments.Electronic supplementary materialThe online version of this article (doi:10.1186/s12284-014-0030-5) contains supplementary material, which is available to authorized users.

“…14 In another recent report, we demonstrated that SNP and IBA could induce OsHO1 mRNA expression. 15 LR formation and HO activity induced by SNP and IBA was reduced by cPTIO and Zn protoporphyrin (ZnPPIX, the specific inhibitor of HO). 15 It seems that HO is required for auxin-and NO-induced LR formation in rice (Fig.…”
