Differential screening, aimed at the isolation of cDNA clones of mRNAs whose accumulation is influenced by GA3, resulted in the isolation of a cDNA clone of an mRNA whose level was decreased by GA3 in segments of epicotyls of Vigna angularis. The putative protein encoded by this cDNA resembled the 1-aminocyclopropane-1-carboxylate oxidases (ACC oxidases) identified in other plant species (about...

Heat stress or global warming is a continuous temperature fluctuation that affects the environment and damage plant tissues because of hormonal imbalances in plants. Yield losses resulting from heat are major threat to food security. Plant growth-promoting bacteria (PGPB) may be utilized lessen this loss yield. PGPB containing aminocyclopropane-1-carboxylic acid (ACC) deaminase activity can enh...

Ethylene, the first known gaseous phytohormone, is involved in plant growth, development as well as responses to environmental signals. However, limited information is available on the role of ethylene in endophytic fungi induced secondary metabolites biosynthesis. Atractylodes lancea is a traditional Chinese herb, and its quality depends on the main active compounds sesquiterpenoids. This work...

Both ethylene and the enzymes of ethylene synthesis are subjects of intensive scientific investigation. The present review discusses structure, catalytic activity and evolutionary relationships of 1-aminocyclopropane-1-carboxylate synthase, identified for the first time in ripening tomato in 1979. This enzyme is responsible for the conversion of S-adenosyl-L-methionine to 1-aminocyclopropane-1-...

Abstract Background The blast disease of rice caused by the fungus Magnaphorthe oryzae is one most destructive diseases in Nam Dinh province, Vietnam. This study aimed to isolate and screen antagonistic bacteria isolated from ( Oryza sativa ) against M. . Results In present study, 14 endophytic were roots a Ngoc Xuan variety province. result showed that 6 isolates vitro activity Of 6, 2 strains...

Root?associated microbial communities play important roles in the process of adaptation plant hosts to environment stressors, and this perspective, microbiome halophytes represents a valuable model for understanding contribution microorganisms tolerance salt. Although considered as most promising halophyte candidate crop cultivation, Salicornia ramosissima is one least-studied species terms com...

The enzyme 1-aminocyclopropane-1-carboxylate (ACC) deaminase promotes plant growth by sequestering and cleaving plant-produced ACC thereby lowering the level of ethylene in the plant. Decreased ethylene levels allow the plant to be more resistant to a wide variety of environmental stresses. Here the biochemical reaction mechanisms involved in ACC deaminase activity are critically reviewed.

Arabidopsis thaliana BOTRYTIS-INDUCED KINASE1 (BIK1) regulates immune responses to a distinct class of pathogens. Here, mechanisms underlying BIK1 function and its interactions with other immune response regulators were determined. We describe BIK1 function as a component of ethylene (ET) signaling and PAMP-triggered immunity (PTI) to fungal pathogens. BIK1 in vivo kinase activity increases in ...
