Fe and P Deficiency Responses
Fe and P deficiency responses, which enable plants to improve their ability to acquire these nutrients, show many similarities.  Iron (Fe) and phosphorus (P) are two essential elements for plant growth whose nutrition is closely related. Both elements are abundant in soils but with poor availability for plants, which favor their acquisition by developing root morphological and physiological responses. Ethylene (ET) and nitric oxide (NO) have been involved in the regulation of both Fe and P related acquisition genes. The common involvement of ET and NO suggests that they must act in conjunction with other specific signals, more closely related to each deficiency, to avoid the induction of the specific responses when ET/NO increase due to other nutrient deficiencies or stresses. Besides the specificity conferred by these signals, ET itself could confer specificity to the responses to Fe- or P-deficiency by acting through different signaling pathways in each case.

Abiotic Stresses Response of Crop
In nature, plants are exposed to an ever-changing environment with increasing frequencies of multiple abiotic stresses. These abiotic stresses act either in combination or sequentially, thereby driving vegetation dynamics and limiting plant growth and productivity worldwide. Most abiotic stresses, occurring either in combination or sequentially, adversely influence the earth crust by modifying the physico-biochemical properties of water, soil, atmosphere, and consequently, plants face hostile conditions. Combined or sequential occurrences of abiotic stresses can damage the crops more significantly than their individual occurrences during various developmental stages. In response to these abiotic stresses, plants develop innumerable physiological, biochemical, cellular and molecular mechanisms to sense and respond against different abiotic stresses.

HR-MAS NMR in Plant Metabolomics
Metabolomics is used to reduce the complexity of plants and to understand the underlying pathways of the plant phenotype. The metabolic profile of plants can be obtained by mass spectrometry or liquid-state NMR. Extraction of metabolites from the sample is necessary for both techniques to obtain the metabolic profile. This extraction step can be eliminated by making use of high-resolution magic angle spinning (HR-MAS) NMR which allows to get metabolic profile directly in intact plant tissues such as intact leaves. An HR-MAS NMR-based metabolomics workflow is thus established that provide a novel platform for obtaining important information of regular metabolic network non-invasively.

Two phytochrome A Types in Plants
The phytochrome (phy) system of plants with the main phyA and phyB controls their development beginning from seed germination to fruiting and senescence. The regulation reactions are categorized into three modes—the very low and low fluence responses (VLFR and LFR) and the high irradiance responses (HIR). The phyA is unique among the other phytochromes; it is major in etiolated seedlings and light-labile, and mediates all the three photoresponse modes. The phyB is light-stable, dominates in deetiolated plants, and performs the LFR. The phyA is itself heterogeneous which may explain its functional complexity. It comprises two native types, phyA′ and phyA″, the products of post-translational modification of the molecule at the N-terminus, possibly, via serine phosphorylation. This alters chromophore-apoprotein interactions resulting in the different photochemical, phenomenological, and functional properties of the two phyA pools. The phyA′ is major, water-soluble, and light-labile; the phyA″ is minor, amphiphilic, and relatively light-stable. The phyA′ mediates the VLFR whereas the water-soluble fraction of phyA″ is responsible for the HIR and LFR, the processes taking place in the nucleus. The membrane- (protein-) associated fraction of phyA” is likely to participate in the cytoplasmic photoregulation processes. The phyA pools' functions—their mode, intensity and sign—depend on plant's species, genotype and organ/tissue. The evidence of the existence of the two distinct phyA types in a plant, and their physicochemical properties and their role in the phyA functioning are discussed.

Cross-Talk during Non-Climacteric Fruit Development and Ripening
Fleshy fruits are characterized by having a developmentally and genetically controlled, highly intricate ripening process, leading to dramatic modifications in fruit size, texture, color, flavor, and aroma. Climacteric fruits such as tomato, pear, banana, and melon show a ripening-associated increase in respiration and ethylene production and these processes are well-documented. Recent studies have shown that non-climacteric fruit development and ripening, involves the coordinated action of different hormones, such as abscisic acid (ABA), auxin, gibberellins, ethylene, and others.

Plant Breeders’ Rights
Plant breeders’ rights (PBRs) are an important IP right, and as plant breeding has a crucial role to play in sustainability, it is vital that innovations in plant breeding receive the appropriate innovation incentives. The full breeders’ exemption ensures that there is always free access to the plant variety protected by a PBR for developing new varieties. The price to pay for this exemption is that PBR holders cannot prevent third parties from taking advantage of their efforts and investments in developing a new variety. This invites free-riding, at the detriment of the PBR holder. The concept of “essentially derived varieties” (EDV), introduced in 1991, provided a “fix” for this problem. It allows PBR holders to extend, at least to some extent, the scope of protection of their PBR to those varieties which use all or most essential characteristics of the initial protection variety. Decades have passed, but no adequate interpretation of the complex EDV concept has been found. The advent of new breeding techniques (NBTs) has made the discussion about a fair scope of protection of PBRs all the more relevant. This necessitates a modernization of the EDV concept, if the PBR system is to remain relevant and continue to be an innovation-incentivizing mechanism. This review introduces a fair interpretation of the EDV concept and a new access reward model.

Sugars and CKs in seeds
Plants adjust their growth and development through a sophisticated regulatory system integrating endogenous and exogenous cues. Many of them rely on intricate crosstalk between nutrients and hormones, an effective way of coupling nutritional and developmental information and ensuring plant survival. Sugars in their different forms such as sucrose, glucose, fructose and trehalose-6-P and the hormone family of cytokinins (CKs) are major regulators of the shoot and root functioning throughout the plant life cycle.

Strobilanthes Callosus
Strobilanthes callosa Nees (Synonym: Carvia callosa (Nees) Bremek) is a shrub found mainly in the low hills of the western ghats all along the west coast of India . Its standardized Hindi language name is Maruadona (मरुआदोना) by which it is called in the state of Madhya Pradesh where it is also found. In the state of Maharashtra in the Marathi language and other local dialects and in the neighboring state of Karnataka the shrub is locally known as Karvi, sometimes spelled in English as Karvy. This shrub belongs to the genus Strobilanthes which was first scientifically described by Nees in the 19th century. The genus has around 350 species, of which at least 46 are found in India. Most of these species show an unusual flowering behaviour, varying from annual to 16-year blooming cycles, on the national scale there is often confusion about which plant is flowering.

Berberis lycium
Study of reproductive biology and pollination ecology helps in understanding the life history patterns of species. Such a study brings to light the bottlenecks, if any, on account of which the individuals of the species are not able to reproduce in nature and ultimately helps in planning appropriate conservation strategies for the species under threat. The present study was aimed at examining the morphological and reproductive variance in Berberis lycium, a threatened ecological specialist growing within shrubberies and open hillsides of the North-Western Himalayas in India. B. lycium displays three different variants. Flowering period ranges from February to September. Pollen viability as reported on fluorescein diacetate and acetocarmine treatments was highest for variant I, while maximum pollen output was obtained for variant III. Pollen pistil interaction is brought by the movement of anther towards stigma. Fluorescence microscopy of hand pollinated club shaped stigma shows that the germinating pollen form a ring over the receptive adaxial surface. Pollination syndrome is entomophily. Variant II attracts a significantly large number of pollinators from diverse insect families. Breeding experiments reflect that plants are self-compatible and cross fertile. Reproductive output (% fruit set) was highest for variant II followed by III and I, respectively.

Ameliorate Concanavalin A-Induced Liver Injury
Liver diseases represent a threat to human health and are a significant cause of mortality and morbidity worldwide. Autoimmune hepatitis (AIH) is a progressive and chronic hepatic inflammatory disease, which may lead to severe complications. Concanavalin A (Con A)-induced hepatic injury is regarded as an appropriate experimental model for investigating the pathology and mechanisms involved in liver injury mediated by immune cells as well as T cell-related liver disease. Despite the advances in modern medicine, the only available strategies to treat AIH, include the use of steroids either solely or with immunosuppressant drugs. Unfortunately, this currently available treatment is associated with significant side-effects. Therefore, there is an urgent need for safe and effective drugs to replace and/or supplement those in current use. Natural products have been utilized for treating liver disorders and have become a promising therapy for various liver disorders.

Factors Affecting Dynamic Photosynthesis under Changing Light
Major research on photosynthesis has been carried out under steady light. However, in the natural environment, steady light is rare, and light intensity is always changing. Changing light affects (usually reduces) photosynthetic carbon assimilation and causes decreases in biomass and yield. Ecologists first observed the importance of changing light for plant growth in the understory; other researchers noticed that changing light in the crop canopy also seriously affects yield.
