“…Symbiotic interaction between legume plants and rhizobacteria is a complex physiological process, which is regulated by a number of signals produced both macro- and microsymbionts [ 16 , 17 ]. Infection by rhizobia increases ROS production, intensifying oxidative processes in plants [ 17 ]. There is a strong evidence that ROS and antioxidant system play a key role in the formation and functioning of legume-rhizobium symbiosis [ 17 , 18 ].…”

Most legume species have the ability to establish a symbiotic relationship with soil nitrogen-fixing rhizobacteria that promote plant growth and productivity. There is an increasing evidence of reactive oxygen species (ROS) important role in formation of legume-rhizobium symbiosis and nodule functioning. Environmental pollutants such as chromium compounds can cause damage to rhizobia, legumes, and their symbiosis. In plants, toxic effects of chromium(VI) compounds are associated with the increased production of ROS and oxidative stress development as well as with inhibition of pigment synthesis and modification of virtually all cellular components. These metabolic changes result in inhibition of seed germination and seedling development as well as reduction of plant biomass and crop yield. However, if plants establish symbiosis with rhizobia, heavy metals are accumulated preferentially in nodules decreasing the toxicity of metals to the host plant. This review summarizes data on toxic effects of chromium on legume plants and legume-rhizobium symbiosis. In addition, we discussed the role of oxidative stress in both chromium toxicity and formation of rhizobial symbiosis and use of nodule bacteria for minimizing toxic effects of chromium on plants.

“…In symbiosis, ROS and antioxidants play defensive roles during rhizobial invasion ( Glyan’ko et al, 2007 ) and antioxidants are crucial for generating the low oxygen environment necessary for N 2 -fixation ( Becana et al, 2000 , 2010 ; Glyan’ko and Vasil’eva, 2010 ). To date, the antioxidant pathway has been investigated by overexpressing SOD in Medicago sativa ( Rubio et al, 2001 ) and overexpressing glutathione synthase and homoglutathione synthetase in Medicago truncatula ( Frendo et al, 2005 ), but overexpressing and silencing approaches have not previously been applied to PPO and the role, if any, of PPO in oxygen scavenging or redox reactions during normal plant physiology, growth and development of nodules is still to be elucidated.…”

“…Nodules of a range of legumes, with determinate ( Chakraborty and Mandal, 2008 ; Mandal et al, 2009 ; Bargaz et al, 2013 ; Webb et al, 2013 ) or indeterminate ( Datta and Basu, 1998 ; Glyan’ko et al, 2007 ; Webb et al, 2013 ) growth morphologies have measurable PPO activity. In the indeterminate nodules of red clover, PPO activity is high and is detected in specific cells and tissues ( Webb et al, 2013 ).…”

“…At least three classes of PPO enzymes reside in nodules, making the nodule a complex environment to study: the host plant itself produces a laccase (EC 1.10.3.2) as well as an enzyme with tyrosinase and catechol oxidase activities (EC 1.10.3.1), while free-living rhizobia also have tyrosinase activity (EC 1.14.18.1). Is the presence of plant PPO in nodules simply a localized defensive response to invasion and colonization by rhizobium bacteria ( Glyan’ko et al, 2007 ) or has PPO activity an additional function?…”

Polyphenol oxidase affects normal nodule development in red clover (Trifolium pratense L.)

et al. 2014

Polyphenol oxidase (PPO) may have multiple functions in tissues depending on its cellular or tissue localization. Here we use PPO RNAi transformants of red clover (Trifolium pratense) to determine the role PPO plays in normal development of plants, and especially in N2-fixing nodules. In red clover, PPO was not essential for either growth or nodule production, or for nodule function in plants grown under optimal, N-free conditions. However, absence of PPO resulted in a more reduced environment in all tissues, as measured by redox potential, and caused subtle developmental changes in nodules. Leaves and, to a lesser extent nodules, lacking PPO tended to accumulate phenolic compounds. A comparison of nodules of two representative contrasting clones by microscopy revealed that nodules lacking PPO were morphologically and anatomically subtly altered, and that phenolics accumulated in different cells and tissues. Developing nodules lacking PPO were longer, and there were more cell layers within the squashed cell layer (SCL), but the walls of these cells were less thickened and the cells were less squashed. Within the N2-fixing zone, bacteroids appeared more granular and were less tightly packed together, and were similar to developmentally compromised bacteroids elicited by catalase mutant rhizobia reported elsewhere.
