In the second part, various promoters showing high-level constitutive, organ-specific, or inducible expression, are summarized as useful tools for realizing the efficient transcription of transgenes.
In the first axis of the MFA drought effect variables (ΔDC/C) and SOURSTAc had positive coordinates while constitutive organ number related variables and SOURSTA ΔDC/C had negative coordinates (Figure 2).
Alkaloid biosynthesis and accumulation are constitutive, organ- and cell type-specific processes in the plant.
Different types of promoters have been used in plant transformation research; these promoters can be divided into three classes: constitutive promoter, organ-specific promoter and inducible promoter (Potenza et al. 2004).
In other words, plants invest in constitutive defenses for organs of high value (e.g., reproductive organs, stems) and likelihood of attack (e.g., young parts), while parts of lower value or likelihood of attack (e.g., leaves) are typically protected through induced defenses [15] [18].
It thus appears there is a preferential uptake of the tracer by the fibrous collagen as compared to constitutive collagen in organs.
Rebolledo et al. (2012) reported a negative constitutive linkage between organ size and number, both contributing to early vigour.
OsHox32 exhibited constitutive expression in different organs, with higher mRNA levels in the stem, leaf sheath, shoot apical meristems and young roots, suggesting a role in plant-type and leaf development.
CXCL8_L2 showed high constitutive expression in immune organs (spleen, head kidney).
Gene-specific primers were designed for 19 unique IiDIRs and were used to evaluate patterns of constitutive expression in different organs.
In keeping with this concept, progressive enlargement of intratissue lymphoid structures and local B-cell enrichment can be associated with acquisition of molecular, cellular, and structural features constitutive of secondary lymphoid organs.
