Integrative Analysis of Transcriptome, Proteome, and Phosphoproteome Reveals Potential Roles of Photosynthesis Antenna Proteins in Response to Brassinosteroids Signaling in Maize

“…In previous studies, Zm00001d009589 (lhcb3) was shown to be involved in chloroplast development. Additionally, Zm00001d009589 (lhcb3) and Zm00001d011285 (lhcb10) respond to drought resistance [ 70 , 71 ]. BR can regulate plant growth and drought responses through the WRKY TF family [ 54 ].…”

Excitation energy equilibration in a trimeric LHCII complex involves unusual pathways

“…An example of such renormalization is given in ref. 40, where we model the Lhca1 complex with modified Redfield and compare the results with the complex time-dependent Redfield 50 and HEOM. In the case of LHCII the Redfield-Fo ¨rster and HEOM pictures also require different site energies in order to give correct exciton structures (because of different reorganization shifts of the exciton levels in these two approaches).…”

“…That is why the Redfield–Förster approach is still more suitable for building the exciton models of antenna complexes. On the other hand, the HEOM solution can be used as a benchmark allowing verification of the obtained models (at least for one realization of the disorder), as was demonstrated in modeling of LHCII, 36 Lhca1, 40 and Lhca4 41 complexes.…”

Excitation dynamics in photosynthetic light-harvesting complex B850: exact solution versus Redfield and Förster limits

“…LHCII, 46 Lhca4, 47 and Lhca1. 35 It was concluded that both ctR and HEOM give significant (and non-uniform) red-shifting of the exciton transitions as compared to mR. Comparison of the energy transfer kinetics calculated with mR and HEOM 34,46–49 revealed another mR artifact connected to its secular character (the same artifact is also present in the coherent modified Redfield theory (cmR), 50–52 which is also a secular theory including only decay of the initial one-exciton coherences).…”

“…In the mR approach the lineshapes are calculated with explicit inclusion of the diagonal exciton-phonon coupling, 27 whereas off-diagonal coupling is accounted for by a phenomenological Markovian term determined by the inverse lifetime of the exciton states (the thus defined term is real and describes a relaxation-induced broadening). 34,35 Besides, more versatile theories of absorption lineshapes have been developed, [36][37][38][39][40][41][42][43] containing non-Markovian generalizations of the modified Redfield lineshapes. Comparison of the absorption spectra calculated with the mR, complex time-dependent Redfield (ctR) theory, 40,42 and nonperturbative hierarchical equation of motion (HEOM) approach 44,45 has been done for model systems 40 and for real antenna complexes from higher plants, i.e.…”
