WebNov 17, 2024 · Another Hd3a role in rice as mobile signal that induced branching was reported by Tsuji et al. . Their findings suggest that Hd3a was moved along the xylem to … WebApr 1, 2015 · Abstract. Accumulating evidence indicates that the FLOWERING LOCUS T (FT) protein is the mobile floral signal known as florigen. A rice FT homolog, Heading date 3a (Hd3a), is transported from the phloem to shoot apical cells, where it interacts with 14-3-3 proteins and transcription factor OsFD1 to form a florigen activation complex (FAC) that ...
Physiological causes of transplantation shock on rice growth
WebOct 6, 2024 · These branching patterns are modulated by two processes: AM formation and axillary bud outgrowth. Several transcription factors (TFs) that regulate these processes have been identified. Various plant hormones, including strigolactones and auxin, have major roles in controlling these TFs. WebSep 1, 2024 · Rice Early heading date 1 (Ehd1) is a type-B response regulator and promotes floral transition under short-day (SD) conditions through upregulating the expression of Hd3a, encoding rice florigen [5]. Ectopic expression of Ehd1 results in early heading under SD conditions and reduces the numbers of primary branches and … s ergo wheelchair
Hd3a promotes lateral branching in rice. - Abstract
WebDec 20, 2024 · Summary Rice is a facultative short day (SD) plant. In addition to serving as a model plant for molecular genetic studies of monocots, rice is a staple crop for about half of the world’s population. Heading date is a critical agronomic trait, and many genes controlling heading date have been cloned over the last 2 decades. WebWe show here that the Hd3a protein accumulates in axillary meristems to promote branching, and that FAC formation is required. Analysis of transgenic plants revealed that Hd3a promotes branching through lateral bud outgrowth. Hd3a protein produced in the phloem reached the axillary meristem in the lateral bud, and its transport was required … WebHd3a protein produced in the phloem reached the axillary meristem in the lateral bud, and its transport was required for promotion of branching. Moreover, mutant Hd3a proteins defective in FAC formation but competent with respect to transport did not promote branching. Finally, we show that Hd3a promotes branching independently from ... the tangled series
