“…Moreover, the study also suggested a higher grain yield of 22-63% in RCc3:OsNAC5 under drought conditions. Kumar et al [87] developed transgenic tomato showing enhanced tolerance to salt and drought stress by the expression of Osmotin-like protein and chi11 genes. The research also reported the significant role of phosphofructokinase2 in the enhancement of root biomass [87].…”

Chitinases—Potential Candidates for Enhanced Plant Resistance towards Fungal Pathogens

Crop cultivation is crucial for the existence of human beings, as it fulfills our nutritional requirements. Crops and other plants are always at a high risk of being attacked by phytopathogens, especially pathogenic fungi. Although plants have a well-developed defense system, it can be compromised during pathogen attack. Chitinases can enhance the plant's defense system as they act on chitin, a major component of the cell wall of pathogenic fungi, and render the fungi inactive without any negative impact on the plants. Along with strengthening plant defense mechanisms, chitinases also improve plant growth and yield. Chitinases in combination with recombinant technology can be a promising tool for improving plant resistance to fungal diseases. The applicability of chitinase-derived oligomeric products of chitin further augment chitinase prospecting to enhance plant defense and growth.

“…The elaboration of effective protocols which allow to micropropagate of valuable plant species is also prerequisite for genetic transformation procedures that may improve their potential for environmental remediation (Doran 2009 ; da Conceição Gomes et al 2016 ; Das et al 2016 ). A feasible and rather cost-effective alternative to genetic manipulation could be the acquisition of resistant plant material by in vitro selection (Wiszniewska et al 2015 ; Kumar et al 2016 ). This approach can operate under wholly controlled conditions, with limited space, and can considerably shorten the time needed for searching of desirable traits under given selection pressure with minimal environmental interaction (Ribalta et al 2014 ).…”

In vitro techniques may provide a suitable tool for effective propagation and conservation of plant species representing various ecological niches. The elaboration of such protocols is also prerequisite for selection of heavy-metal-tolerant plant material that could be afterwards used for restoration or remediation of polluted sites. In this study, culture protocol for Gypsophila fastigiata propagation was developed. The highest multiplication coefficient, which reached 6.5, and the best growth parameters were obtained on modified MS medium supplemented with 1.0 mg L−1 2iP and 0.2 mg L−1 IAA. The obtained cultures were treated with different concentrations of lead nitrate (0.1, 0.5, and 1.0 mM Pb(NO3)2) or cadmium chloride (0.5, 2.5, and 5.0 μM CdCl2). The growth parameters, photosynthetic pigments, and phenolic compound content were examined in order to evaluate whether tested metal salts can have an adverse impact on studied culture. It was ascertained that Pb ions induced growth disturbances and contributed to shoot wither. On the contrary, the proliferative shoot cultures were established on media containing Cd ions and the multiplication coefficients and shoot length increased on all media enriched with CdCl2. Chlorophylls and carotenoid contents were negatively affected by application of 5.0 μM of cadmium; nevertheless, in shoots treated with 2.5 μM CdCl2, increased accumulation of photosynthetic pigments occurred and their amount was similar to untreated culture. Adaptation to Cd was associated with stimulation of phenolic compound synthesis. Hence, we have reported on unambiguous positive result of in vitro selection procedure to obtain vigorous shoot culture tolerant to cadmium.Electronic supplementary materialThe online version of this article (10.1007/s11270-018-3702-8) contains supplementary material, which is available to authorized users.

“…OSMs (Table 3 ) are members of the Pathogenesis-related Protein 5 (PR-5) family [ 62 ], and can strengthen plant membrane stability and resistance to multiple stresses [ 63 – 65 ]. The genes coding for OSMs or osmotin-like proteins (OLPs) impart increased resistance by up-regulating the expression of genes coding for ROS-scavenging enzymes and defense-related marker genes and participate in the cold acclimation of plants [ 66 , 67 ].…”

BackgroundThe artificial enlargement of the planting area and ecological amplitude of ornamentals for horticultural and landscape applications are significant. Herbaceous peony (Paeonia lactiflora Pall.) is a world-famous ornamental with attractive and fragrant flowers and is mainly planted in temperate and cool areas. Comparatively higher winter temperatures in the subtropical and tropical Northern Hemisphere result in a deficit of chilling accumulation for bud dormancy release, which severely hinders “The southward plantation of herbaceous peony”. Studies on the dormancy, chilling requirement (CR) and relevant molecular mechanisms of peony are needed to enhance our ability to extend the range of this valuable horticultural species.ResultsBased on natural and artificial chilling experiments, and chilling hour (CH) and chilling unit (CU) evaluation systems, the lowest CR of ‘Hang Baishao’ was between 504.00 and 672.00 CHs and the optimal CR was 672.00 CHs and 856.08 CUs for achieving strong sprouting, growth and flowering performance. Transcriptome sequencing and gene identification by RNA-Seq were performed on ‘Hang Baishao’ buds during the dormancy and sprouting periods. Six gene libraries were constructed, and 66 temperature- and photoperiod-associated unigenes were identified as the potential candidate genes that may regulate or possibly determine CR characteristics. The difference in the expression patterns of SUPPRESSPOR OF OVEREXPRESSION OF CONSTANS1 (SOC1) between the winters of 2012–2013 and 2015–2016, and the difference of CR fulfillment periods also between these two winters represented the interesting congruent relationships. This correlation was also observed for WRKY DNA-BINDING PROTEIN 33 (WRKY 33).ConclusionsCombined with the results acquired from all of experiments, ‘Hang Baishao’ was confirmed to be a superb peony resource that have significantly low CR characteristics. The two genes of SOC1 and WRKY33 are likely involved in determining the CR amount and fulfillment period of ‘Hang Baishao’. HEAT SHOCK PROTEIN, OSMOTIN and TIMING OF CAB EXPRESSION 1 also deserve attention for the CR research. This study could contribute to the knowledge of the deep factors and mechanisms that regulate CR characteristics, and may be beneficial for breeding new germplasms that have low CRs for landscape or horticulture applications in subtropical regions.Electronic supplementary materialThe online version of this article (10.1186/s12870-017-1205-1) contains supplementary material, which is available to authorized users.
