“…The blue (B) and red (R) light regions of the light spectrum are most efficiently utilized for the photosynthesis; thus, B light-sensing cryptochrome (cry) and R light-absorbing phytochrome (phy) play major roles in regulating plant light responses, such as light-dependent seed germination, de-etiolation, SAS and photoperiodic flowering [3][4][5]. Importantly, crys or phys also mediate important agronomic traits in crop species [4][5][6]. For example, rice mutants defective in all phy proteins set very few seeds [7].…”

Abstract:In nature, plants integrate a wide range of light signals from solar radiation to adapt to the surrounding light environment, and these light signals also regulate a variety of important agronomic traits. Blue light-sensing cryptochrome (cry) and red/far-red light-sensing phytochrome (phy) play critical roles in regulating light-mediated physiological responses via the regulated transcriptional network. Accumulating evidence in the model plant Arabidopsis has revealed that crys and phys share two mechanistically distinct pathways to coordinately regulate transcriptional changes in response to light. First, crys and phys promote the accumulation of transcription factors that regulate photomorphogenesis, such as HY5 and HFR1, via the inactivation of the CONSTITUTIVE PHOTOMORPHOGENIC1/SUPPRESSOR OF PHYA-105 E3 ligase complex by light-dependent binding. Second, photoactive crys and phys directly interact with PHYTOCHROME INTERACTING FACTOR transcription factor family proteins to regulate transcriptional activity. The coordinated regulation of these two pathways (and others) by crys and phys allow plants to respond with plasticity to fluctuating light environments in nature.

“…Considering that Sorghum has a strong adaptability to the environment, these analyses imply that Sorghum genes related to drought tolerance, salt tolerance, cytochrome, dehydrin, high temperature tolerance, disease and insect resistance can functionally enhance rice yield. This reveals that some evolutionarily homologous genes may show different functions when alien genes were expressed in different plant species (Gururani et al 2015;Hong et al 2014), and provide a novel approach to explore gene resources for plant improvement.…”

The improvement of rice productivity is an important subject due to great population pressure. As plant functional genomics rapidly develops, increasing numbers of genes from different organisms are documented for rice improvement. Sorghum, a relative of rice, has many novel phenotypic characteristics such as strong stature, large panicle, drought tolerance, and a tolerance for low soil fertility, making this species an excellent gene resource for rice improvement. A Sorghum cDNA library was transformed into rice generating an overexpression population with 1153 fertile transgenic lines. Over 900 of these lines displayed phenotypic changes including: plant height, leaf shape and size, effective panicles, and other vegetative characteristics. Importantly, there were 19 lines with higher grain yield than the wild type, which demonstrates that the high-throughput transformation of overexpressing transgenes from Sorghum into rice is a highly efficient method for rice improvement.

“…Photo-biotechnology refers to over-or down-expressing genes with photo-biological relevance [159]. Since photoreceptors and/or light signalling cascade components regulate the expression of critical development and plant growth genes, genetic manipulation of these is viewed as a promising strategy to develop fruit crops with improved agronomic traits [159].…”

“…Since photoreceptors and/or light signalling cascade components regulate the expression of critical development and plant growth genes, genetic manipulation of these is viewed as a promising strategy to develop fruit crops with improved agronomic traits [159]. Therefore, photo-biotechnology offers a promising approach for studying the influence of UV-B signal transduction components on plant development and may be used to improve crop yield, shade tolerance, growth and fruit ripening, canopies shape, hormone synthesis and biosynthesis of metabolites and pigments.…”

“…These results demonstrate that genes encoding components of UV-B signalling cascade represent a promising genetic tool for manipulation of fruit quality. Additionally, several studies summarized by [159] in various plant species show that modulation of the expression of phytochromes (mainly PhyA and PhyB) can be used to produce high-yielding crops.…”

Grapevine is one of the most abundant crops worldwide, with varieties destined for fresh and dry consumption, as well as wine production. Unfortunately, grapevine plants are affected by both biotic and abiotic stresses, generating significant economic losses. These conditions can negatively impact grape cultivation at different stages: plant and berry development during pre-and post-harvest, production, fresh fruit processing and export, along with wine quality. Most of the grapevine varieties are susceptible to several pathogens and within this chapter, particular attention is given to fungi (Botrytis cinerea and Erysiphe necator) and viruses, since they are a worldwide concern. Within the latter, special focus is given to the grapevine leafroll disease, a complex and destructive infection. On the other hand, abiotic stress is also relevant in grapevine, and in this chapter it will be exemplified by UV-B radiation and its impact on growth and fruit development, plant adaptive responses and its relationship with the quality of grape berries for winemaking. The main biotic and abiotic grapevine stress factors are reviewed in this chapter, considering a special focus on biotechnological approaches carried out in order to address them and minimize their detrimental consequences.
