“…The increased fibre content might be due to the existence of lignin as a component of plant defence system, being distinct from developmental fibre, which is induced by stress factors such as salinity and drought (Stange Jr et al, 2001). This is in an agreement with a previous study where alfalfa plants were shown to possess increased fibre content as a result of defensive response against abiotic stress (Zhang et al, 2016).…”

The aim of this study was to confirm the presence of BADH gene and control whether it plays an important role to protect white clover (Trifolium repens L.) against oxidative, salt, and drought stresses. Three genotypes possessing BADH and 1 genotype lacking BADH were selected, considering the expression levels of BADH in response to methyl viologen mediated oxidative stress. The genotypes possessing BADH displayed significantly less ion leakage under oxidative stress treatment, compared to that lacking BADH. In order to test salinity tolerance, the plants were treated with 300 mM NaCl for 2 weeks, and to mimic drought conditions, plants were grown without irrigating for 5 days. Under the salt stress, the plants possessing BADH contained lower malondialdehyde levels and higher chlorophyll contents than that of plants lacking BADH. Similarly, under the drought conditions, the plants possessing BADH were found to have increased levels of glycinebetaine, proline, and high relative water contents than the plant lacking BADH. These findings indicate that the plants having BADH exhibited enhanced tolerance to salt and drought stresses. These enhanced tolerances of plants possessing BADH gene is attributed to its ability to induce glycinebetaine synthesis. Moreover, the plants possessing BADH were found to exhibit higher relative feed value under both stress and normal conditions. These plants could be used as forage crops on marginal areas having salinity or drought problems.

“…In the present study, changes in lignification were documented over treatments and also genotypes. Similarly, increased lignification on chickpea towards S. rolfsii infection (Singh et al, 2013) and on alfalfa towards Rhizobium meliloti infection (Zhang et al, 2016) had been demonstrated. The microscopic images on lignification have a clear line with our phenolic profiling as follows; intense lignification observed on B. cinerea challenged and consortium treated stem sections might have appeared due to the induction of hydroxycinnamic acid derivatives and flavonoids of the same group over control group.…”

Two hundred and fifty seven actinobacteria, isolated from five different rhizosphere soils of chickpea, were evaluated for their antagonistic potential against Botrytis cinerea, causal agent of Botrytis grey mold (BGM) disease in chickpea, by dual culture assay. Of them, three most promising isolates (ATIRS43, ATIRS65 and ARRS10) with highest inhibitory activity (67-77%) were identified as Streptomyces sp. These selected isolates induced growth of chickpea genotype JG11 as a consortium rather than an individual inoculum. Co-inoculation of the selected Streptomyces sp. with Mesorhizobium ciceri UPM-Ca7 T enhanced nodulation and nitrogenase activity in five chickpea genotypes (ICCV2, ICCV10, ICC4958, Annigeri and JG11). The selected Streptomyces sp. significantly reduced the disease incidence caused by B. cinerea by 28-47% over the un-inoculated control across the chickpea genotypes ICC4954 (susceptible), ICCV05530 (moderately resistant) and JG11 (unknown resistance). The Streptomyces sp. were also able to induce host-plant resistance, irrespective of the genotype, through the induction of various antioxidant enzymes and phenolics. Phenolic profiling of B. cinerea-affected and Streptomyces treated plants of ICCV05530 further confirmed hostplant resistance traits. This study indicated that the selected Streptomyces sp. have the potential for biological control of BGM disease in chickpea.

“…Secondly, alfalfa possesses a deep root system that allows it to grow under adverse soil and climate conditions, including arid and semi-arid areas ( Hamidi and Safarnejad, 2010 ). Furthermore, the symbiotic relationship of alfalfa with rhizobia reduces the need for nitrogen fertilizers ( Zhang et al., 2016 ). However, the utilization of alfalfa is limited by its rapidly degradable protein and relatively high lignin content ( Lei et al., 2017 , 2018a ).…”
