Abstract:
... Root formation under natural conditions is plastic in response to multiple signals. Recent studies suggested that the WUSCHEL‐RELATED HOMEOBOX11 (WOX11)‐mediated adventitious root formation pathway can occur in the primary root (PR) in Arabidopsis thaliana, resulting in the production of a specific type of lateral roots (LRs) in response to wounding or environmental signals. This process differs f ...

Abstract:
... Cellulose is an essential morphogenic polysaccharide that is central to the stability of plant cell walls and provides an important raw material for a range of plant-based fiber and fuel industries. The past decade has seen a substantial rise in the identification of cellulose synthesis-related components and in our understanding of how these components function. Much of this research has been con ...

Abstract:
... TERMINAL FLOWER1 (TFL1) was named from knockout Arabidopsis thaliana mutants in which the inflorescence abnormally terminates into a flower. In wild type plants, the expression of TFL1 in the center of the inflorescence meristem represses the flower meristem identity genes LEAFY (LFY) and APETALA1 (AP1) to maintain indeterminacy. LFY and AP1 are activated by flowering signals that antagonize TFL1. ...

Abstract:
... In living organisms, the MicroRNAs act as an important role by controlling regulatory mechanisms, and likely manipulating the output of numerous protein-coding genes. Several computational databases, algorithms and tools have been developed to discover the miRNA target genes. But, the existing methods obtain poorer results in identification of miRNA target gene. Hence in this research work, integr ...

Abstract:
... Long days (LD) promote flowering of Arabidopsis thaliana compared with short days (SD) by activating the photoperiodic pathway. Here we show that growth under very‐SD (3 h) or darkness (on sucrose) also accelerates flowering on a biological scale, indicating that SD actively repress flowering compared with very‐SD. CONSTANS (CO) repressed flowering under SD, and the early flowering of co under SD ...

Abstract:
... TGACG‐BINDING FACTORs (TGAs) control the developmental or defense‐related processes. In Arabidopsis thaliana, the functions of at least TGA2 and PERIANTHIA (PAN) can be repressed by interacting with CC‐type glutaredoxins, which have the potential to control the redox state of target proteins. As TGA1 can be redox modulated in planta, we analyzed whether some of the 21 CC‐type glutaredoxins (ROXYs) ...

The stay-green mutant of Arabidopsis thaliana, ore10 forms stable light-harvesting complex II (LHCII) aggregates during dark-induced senescence, which showed a single base deletion (G1351) in the coding region of the pheophytinase (PPH) gene. PPH specifically dephytylates the Mg-free chlorophyll (Chl) pigment pheophytin, yielding pheophorbide. In both ore10 and pph-1 mutants, pheophytin a accumula ...

Abstract:
... A key component of seed germination is the interplay of mechanical forces governing embryo growth and the surrounding restraining endosperm tissue. Endosperm cell separation is therefore thought to play a critical role in the control of this developmental transition. Here we demonstrate that in Arabidopsis thaliana seeds, endosperm cell expansion is a key component of germination. Endosperm cells ...

Abstract:
... With increasing application of rare earth elements (REEs), the resulting environmental safety has attracted extensive attention. When REEs act on plant leaves, REEs can initiate endocytosis in leaf cells, causing more REEs enter plant cells and then severe damage to plants. But when REEs directly act on plant roots, whether and how REEs affect the endocytosis in root cells remain unknown. Here, we ...

Six commonly occurring folate for ...

Abstract:
... C₃ photosynthesis is often limited by CO₂ diffusivity or stomatal (gₛ) and mesophyll (gₘ) conductances. To characterize effects of stomatal closure induced by either high CO₂ or abscisic acid (ABA) application on gₘ, we examined gₛ and gₘ in the wild type (Col‐0) and ost1 and slac1‐2 mutants of Arabidopsis thaliana grown at 390 or 780 μmol mol⁻¹ CO₂. Stomata of these mutants were reported to be in ...

Abstract:
... Despite photosystem I (PSI) is susceptible to photoinhibition under fluctuating light in wild-type angiosperms, the underlying mechanism is not well known. Because proton gradient (ΔpH) across the thylakoid membranes plays a crucial role in protecting PSI, we hypothesized that PSI photoinhibition under fluctuating light may be linked to the formation of ΔpH. To test this hypothesis, we measured ch ...
