2017年6月1日 · Inhibition of the potato sucrose transporter 4 (SUT4), which does not seem to play a direct role in carbohydrate export from leaves, was shown to strongly reduce the capacity for SAR (Chincinska et al. 2008).

2023年4月4日 · Recent studies have revealed the molecular mechanisms of photosynthesis-, photoreceptor-, and phytohormone-mediated leaf senescence under shade conditions. In this review, we discuss the recent advances in the molecular and genetic understanding of shade-induced leaf senescence.

Sucrose production was high under HL conditions, and we found that sucrose promoted isotropic cell expansion and the endocycle even under LL conditions. Our analyses based on this method of time-course observation addressed the developmental framework of sun- …

2019年7月26日 · In ecological and anatomical terms, thick leaves induced under high light (HL) conditions are called ‘sun leaves’, whereas thin leaves formed under low light (LL) conditions are called ‘shade leaves’ (Haberlandt, 1914).

2023年9月18日 · The present study examined the mature leaves’ sucrose and starch metabolism during grain filling (all leaves mature). The shade treatment reduced the sucrose and starch concentrations of unshaded and shaded leaves compared with T C2 (PAR 1477.5 μmol m −2 s −1); the sugar concentrations of shaded and unshaded leaves decreased with ...

Shade caused the increased elongation growth of the main stem, internode, and leaf, and elongation was positively associated with auxin levels. Shade stress reduced peanut yield. Further comparative RNA-seq analyses revealed expressional changes in many metabolism pathways and common core sets of expressional regulations in all shade treatments.

2023年10月28日 · Here, we report that non-secreted ROT FOUR LIKE (RTFL)/DEVIL (DVL) peptides negatively regulate SAS by interacting with BRASSINOSTEROID SIGNALING KINASEs (BSKs) and reducing the protein level of...

2020年10月1日 · Soybean seedlings were grown in pots and exposed to no shade (S0), slight shade (S1), moderate shade (S2), and heavy shade (S3). Our findings showed that under the S3 in both cultivars, leaf fresh weight (LFW), specific leaf area (SLA) and leaf thickness decreased significantly, accompanied by a reduction in photochemical parameters including ...

2024年12月5日 · Shade-tolerant cultivars (MM-51 and CM-39) adapted to low-light conditions via a higher leaf area of flag leaves, light interception rate, and chlorophyll a and b contents; this increased non-structural carbohydrates and sucrose contents in developing grains, ultimately decreasing yield loss by shade stress. Pre-anthesis shading resulted in a ...

2021年1月1日 · In this review, we evaluate whether sucrose could be a preferred signaling molecule that controls processes like carbohydrate metabolism, accumulation of storage proteins, sucrose transport, anthocyanin accumulation, and floral induction. We summarize putative sucrose-dependent signaling pathways.
