2021年5月15日 · In a yeast 1-hybrid screen with the SIIE, we identified the closely related R2R3-MYB transcription factors TT2 and MYB5. We found overexpression of MYB5 or TT2 rendered plants heat stress tolerant. In contrast, tt2, myb5, and tt2/myb5 loss of function mutants showed heat stress hypersensitivity.

2021年12月15日 · Salt, water, and ABA stress reduced tt2 germination compared to wild-type. Efforts are underway to domesticate the winter annual oilseed cover crop, pennycress (Thlaspi arvense L.), to aid in overcoming global food security and ecosystem challenges.

2012年8月9日 · We demonstrate that the tt2 mutation remarkably increased the seed FA content, decreased seed weight, and altered the FA composition. The increase in FA content in the tt2 seeds was due to the relative decrease of seed coat proportion as well as the more efficient FA synthesis in the tt2 embryo.

2009年1月15日 · Both GL2 and TTG2 have positive roles in trichome outgrowth and branching and in seed coat mucilage production. GL2 also regulates root hair patterning while TTG2 additionally functions in seed coat PA biosynthesis.

2021年12月30日 · Here we identified a natural quantitative trait locus (QTL), TT2 (THERMOTOLERANCE 2), encoding a Gγ subunit, that confers thermotolerance in rice, and revealed a distinct molecular regulation...

2014年1月8日 · TRANSPARENT TESTA2 (TT2) regulates the biosynthesis of proanthocyanidins in the seed coat of Arabidopsis. We recently found that TT2 also participates in inhibition of fatty acid (FA) biosynthesis in the seed embryo. However, the mechanism by which TT2 suppresses the accumulation of seed FA remains unclear.

Genetic analyses have demonstrated that together with TTG1, a WD-repeat (WDR) protein, TT2 (MYB), and TT8 (bHLH) are necessary for the correct expression of BANYULS (BAN). This gene codes for the core enzyme of proanthocyanidin biosynthesis in Arabidopsis thaliana seed coat.

TT2, known for regulating proanthocyanidin production (Nesi et al., 2001), also modulates seed oil content. The tt2 mutant displays increased seed oil content and increased expression of...
