Oxalate is widely distributed in the plant kingdom. While excess oxalate food crops detrimental to animal and human health, it may play various functional roles plants, particularly for coping with environmental stresses. Understanding its biosynthetic mechanism therefore, becomes increasingly important both theoretically practically. However, still a matter of debate as what precursor pathway are ultimately used biosynthesis plants. In this study, physiological molecular approaches were...
Photorespiration is one of the most intensively studied topics in plant biology. While a number mutants deficient photorespiratory enzymes have been identified and characterized for their physiological functions, efforts on glycolate oxidase (GLO; EC 1.1.3.15) not so successful. This report about generation transgenic rice (Oryza sativa L.) plants carrying GLO antisense gene driven by an estradiol-inducible promoter, which allowed controllable suppressions its detailed functional analyses....
NCA1 (NO CATALASE ACTIVITY 1) was recently identified in Arabidopsis as a chaperone protein to regulate catalase (CAT) activity through maintaining the folding of CAT. The gene exists mainly higher plants; some plants, such Arabidopsis, contain only one gene, whereas others rice harbor two copies. It is not yet understood whether and how both isoforms have functioned CAT those two-copy-containing plant species. In this study, we first noticed that spatiotemporal expression patterns NCA1a...
Abstract Exposure to ultraviolet B radiation (UV-B) stress can have serious effects on the growth and development of plants. Germin-like proteins (GLPs) may be involved in different abiotic biotic responses plants, but little is known about role GLPs UV-B response acclimation In present study, knockout GLP 8–14 (OsGLP1) using CRISPR/Cas9 system resulted mutant rice (Oryza sativa L.) plants (herein called glp1) that exhibited UV-B-dependent formation lesion mimic leaves. Moreover, glp1 grown...
Oxalate, a common constituent in many plants, is known to play important functional roles plants. However, excess levels of oxalate edible parts plants adversely affect their quality as food. Understanding the regulatory mechanism particularly food crops, both scientific and practical significance. While number studies have shown that nitrate can efficiently induce accumulation how it elicits such an effect not well understood. This study aimed gain further insight into underlying...
Oxalic acid is widely distributed in biological systems and known to play functional roles plants. The gene AAE3 was recently identified encode an oxalyl-CoA synthetase (OCS) Arabidopsis that catalyses the conversion of oxalate CoA into oxalyl-CoA. It will be particularly important characterise homologous rice since not only a monocotyledonous model plant, but also staple food crop. Various enzymatic methods have been used gene. We first defined genome (OsAAE3) encodes OCS enzyme. Its Km for...
UV RESISTANCE LOCUS 8 (UVR8) has been identified in Arabidopsis thaliana as the receptor mediating responses to UV-B radiation. However, UVR8-mediated signaling pathways rice, which possesses two proteins (UVR8a and UVR8b) with high identities AtUVR8, remain largely unknown. Here, UVR8a/b were found be predominantly expressed rice leaves leaf sheaths, while levels of UVR8b transcript protein both higher than those UVR8a. Compared wild-type (WT) plants, uvr8b uvr8a mutants exposed showed...
Abstract UV RESISTANCE LOCUS 8 (UVR8) has been identified in Arabidopsis thaliana as the receptor for UV-B radiation mediating photomorphogenic responses and acclimation to radiation. However, UVR8-mediated signaling pathways rice, that two proteins (UVR8a UVR8b) with homology AtUVR8, remain largely unknown. In this study, UVR8a UVR8b were found be expressed mainly rice leaves leaf sheaths, while level of was higher than UVR8a. agreement prior studies on uvr8b uvr8a mutants exposed showed...
