Subject: An efficient in vitro haploid induction protocol/method in onion (Alium cepa L.)
Keywords: Doubled haploids, haploids, hybrids, inbreds.
Abstract: As is true in other vegetable crops, hybrids are the major cultivar options in onion as well. Conventional development of near homozygous inbred lines for use as parents of the hybrids takes six to eight years. The development of hybrid parents using doubled haploid technology is the best alternative to this. Toward this effort, we standardized the best protocol to induce haploidy in different open-pollinated onion varieties. Haploid induction is a prelude to development of doubled haploids. The MS and B5 media consisting of 2 mg/l benzyl amino purine (BAP), 2 mg/l 2,4-dichlorophenoxyacetic acid (2,4-D), 2 mM putrescine and 0.1 mM spermidine was found to be the best protocol for haploid induction. The haploid induction frequency varied with the genotypes used in the study. This protocol is expected to hasten the development of doubled haploids in onion.

Subject: Meat consumption in bonnet macaque (Macaca radiata): an analysis on recent observations from Wayanad, Kerala
Keywords: Bonnet macaque, macaque diet, meat eating, micronutrients, Wayanad.
Abstract: Studies on vertebrate feeding among macaques are rare, except for the southern pig-tailed macaque. In this study, we present two instances of bonnet macaques consuming vertebrate meat in a semi-evergreen forest in Wayanad. This marks the first report of a freeranging bonnet macaque feeding on a bird and the first report of any vertebrate consumption by this species since 1978. Our review and analysis of vertebrate feeding among macaques indicate that they engage in vertebrate feeding infrequently, indicating that it is unlikely to be a significant source of protein or energy for them.

Subject: High-resolution reconstruction of images for estimation of plant height in wheat using RGB-D camera and machine learning approaches
Keywords: 3D reconstruction, image processing, Open3D, plant phenotyping, RGB-D imaging.
Abstract: In this study, a pipeline has been proposed where colour image and depth information of wheat plants are captured using an red green blue-depth (RGB-D) camera; later these two are combined to create a three-dimensional point cloud of the plant. The point clouds were processed to calculate the plant height. The results were then statistically analysed with the help of machine learning algorithms, viz. linear regression, support vector machine and artificial neural network (ANN). The comparison of the results shows that ANN performed better than the other two models with mean squared error 189.94, root mean squared error 13.70, mean absolute error 11.40 and mean absolute percentage error 18.73. The proposed study shows a high precision and low-cost technology that can be widely used for non-destructive measurement of phenotyping parameters for wheat and other crops

Keywords: Collagen, epithelialization, nanocrystalline silver, scalds, superficial burns.
Abstract: Second-degree superficial burns are prevalent, with scalds in extremities being the most frequent cause. They are treated initially with dressings such as wet collagen and nanocrystalline silver, and they mostly heal by conservative means, rarely requiring skin grafts. Here we aim to compare the efficacy of nanocrystalline silver and collagen dressings for seconddegree superficial burns and to establish a standard protocol for managing such burns. It indicates that nanocrystalline silver dressings are more effective than collagen dressings in promoting faster epithelialization of second-degree burns and are associated with lower pain levels during treatment. However, there is no significant difference between the two groups regarding the need for split skin thickness grafts

Keywords: Delhi supergroup, exsolution, garnet, pegmatite, quartzite.
Abstract: Quartzites of the Delhi Supergroup, exposed along the Firozpur-Jhirka ridge in Faridabad, Gurgaon areas of Delhi-National Capital Area, host detrital garnet grains. The garnet grains are studied for understanding provenance and diagenetic history. Samples were collected from the Badkhal lake area, Faridabad. X-ray diffraction study identifies quartz, garnet, magnetite and goethite as major mineral phases. Whereas quartzites show recrystallization texture, garnet grains record intense fractures and magnetites form large acicular grains. From electron probe microanalysis garnet grains are identified as almandine with high spessartine content and a pegmatite source is suggested. From preserved in-situ exsolution of magnetite from garnet it is inferred that a temperature exceeding 550°C (>17 km burial depth) in the course of burial history and magnetites exsolved below 550°C from garnet during the uplift of quartzite

Abstract: Potential carbon sequestration in a cropping system depends on biophysical factors like soil type, water availability, agro-climate, land use and tillage practices. The benefit accrued depends on socio-economic factors and legal rights of land, which have been discussed. Potential barriers to adoption and relative importance of such hurdles have been discussed; the relative importance followed the order: knowledge > economic > biophysical > cultural = right to soil. A scale neutral nationwide policy framework for carbon sequestration and attaining land degradation neutrality has also been suggested

Subject: Morpho-taxonomy and molecular intrusion!

Abstract: The present article is partly a follow-up to an editorial in Current Science (2023, 125(11), 1155– 1156) defending taxonomy and concerns about waning landscapes and floras. Some remarks were made on the expositions presented in this editorial. The article reiterates the importance of morphotaxonomy in biodiversity documentation and its sustainable utilization. It explains how molecular taxonomy which does not handle explorations, enumerations, and floras independently grew at the price of morpho-taxonomy. It emphasizes that molecular approaches have quite a few limitations with more convolutedness in experimentation and circumambulation in data processing. Name changes happening, principally below the generic level through molecular approaches and in phylogenetic perspective may destroy the long-existing and established literature/names. Our molecular approaches should be situation specific as needs arise and, more precisely, when taxonomic issues are identified as complexes based on morpho-taxonomy.

Subject: Insights from carbonized seeds: agricultural systems in the lower Ganga Plain (3000 yrs BP)
Keywords: None
Abstract: In the history and archaeology of India, the Ganga Plain has a pronounced position. The Ganga Plain is mainly divided into three main parts: (i) the upper Ganga Plain, (ii) the middle Ganga Plain and (iii) the lower Ganga Plain1,2. It is an important region for archaeobotanical studies as it houses numerous archaeological sites, and was the region where second urbanism emerged in India. Carbonized plant remains from archaeological sites can provide clues crucial for understanding the culture–climate– subsistence relationship during prehistoric times. The gradually growing database on crop remains from excavations in different regions of India during the past few decades has securely established that in addition to the indigenous crops, a continuous and substantial expansion in the kinds of subsistence resources of the Mediterranean, Central Asian, African and Eurasian have made generous dynamism in the economy of the early farming communities3–11. The socio-political, economic and environmental conditions that existed during the last five millennia are of interest among archaeologists, archaeobotanists and quaternary scientists10–14.

Abstract: Madhuca longifolia var. latifolia (Mahua), a member of Sapotaceae, is one of the ecologically and economically important native species, greatly valued for its flowers and seeds. Mahua products play a vital role in income and livelihood of indigenous communities living in and around the forest areas of tropical India. The local community members earn considerable part of their total income from mahua seeds and seed oil1,2. Diversity in the fruit and seeds of this species is an exciting research aspect. Fruits are generally berries, ovoid, fleshy, turning yellowish green when ripe, 3–5 cm long with prominent distal beak. Morphometric study of this reproductive trait resulted a very interesting fact about the presence of single and multiple seeds inside the fruits of mahua.

Keywords: None
Abstract: The state fish of Kerala, Etroplus suratensis (Bloch 1790), pearlspot fish is considered as an important euryhaline species accepted as a very good ‘gourmet choice’ with high market demand. It is extensively distributed in the brackish and freshwaters of India, Sri Lanka, Bangladesh and Pakistan1–7 . The fish is known to exhibit typical biparental monogamy and was found to form mating pairs close to breeding and courtship commenced only between such ‘attached’ pairs8 . Monogamy is found across various animal species, including invertebrates, teleost fishes, mammals and most bird species. Considering the diversity of species exhibiting monogamous behaviour, it is anticipated that different levels of monogamy will occur, ranging from lifelong unions with no promiscuous behaviour to social monogamy, which allows for restricted genetic exchange9 . Here we aim to reassess the presumed lifelong (classical) monogamy observed in pearlspot breeding pairs, as documented in prior studies.

Keywords: None
Abstract: The tiger barb (Puntirgus tetrazona), a popular ornamental fish native to the freshwaters of Indonesia1 was first described in 1855 by Dutch ichthyologist Pieter Bleeker. They inhabit rivers, streams and lakes with moderate waterflow that are clear and turbid with shallow depths. The tiger barb grows up to a maximum length of 7–10 cm and are generally omnivorous and they often swim in schools. It is understood that the gut microbial community in any fish species improves performance of the fish with respect to its size, metabolism, feeding habits and immunity. However, the presence of pathogenic microorganisms needs to be explored as there are no studies and reports regarding the presence of the same in the gut microbiome of the tiger barb raised in fish farms.

Abstract: A gripping example of the glories of coastal ecosystems is the Pichavaram Mangrove Forest, which is tucked away on Tamil Nadu’s eastern coast. This charming mangrove expanse, which covers an area of about 1100 hectares, is well-known for its intricate web of canals, entwined roots, and varied flora and fauna. In addition to producing an aesthetically pleasing landscape, Pichavaram’s complex network of backwaters and canals is an essential breeding site for a wide variety of marine animals. The thick mangrove vegetation, primarily composed of species like Rhizophora and Avicennia, serves as an essential natural barrier against coastal erosion1 . The Pichavaram mangrove forest mainly comprises Rhizophora apiculata, Rhizophora mucronata, Sonneratia apetala, Avicennia marina, Avicennia officinalis, Bruguiera cylindrica, Ceriops decandra and Aegiceras corniculatum . Once Pichavaram was flourishing with mangroves of Aegiceras floridum, Bruguiera gymnorrhiza, Cynometra ramiflora, Kandelia candel and Xylocarpus granatum. The plant Bruguiera gymnorrhiza became extinct from the Pichavaram forest by the end of the 19th century.
