Microsatellites, also known as simple sequence repeats (SSRs), are polymorphic loci that play an important role in genome research, animal breeding, and disease control. Ranch animals are important components of agricultural landscape. The ranch animal SSR database, ranchSATdb, is a web resource which contains 15,520,263 putative SSR markers. This database provides a comprehensive tool for performing end-to-end marker selection, from SSRs prediction to generating marker primers and their cross-species feasibility, visualization of the resulting markers, and finding similarities between the genomic repeat sequences all in one place without the need to switch between other resources. The user-friendly online interface …
Comparative Genome-Wide Analysis Of Micrornas And Their Target Genes In Roots Of Contrasting Indica Rice Cultivars Under Reproductive-Stage Drought, Simardeep Kaur, Karishma Seem, Suresh Kumar, Rakesh Kaundal, Trilochan Mohapatra

Recurrent occurrence of drought stress in varying intensity has become a common phenomenon in the present era of global climate change, which not only causes severe yield losses but also challenges the cultivation of rice. This raises serious concerns for sustainable food production and global food security. The root of a plant is primarily responsible to perceive drought stress and acquire sufficient water for the survival/optimal growth of the plant under extreme climatic conditions. Earlier studies reported the involvement/important roles of microRNAs (miRNAs) in plants’ responses to environmental/abiotic stresses. A number (738) of miRNAs is known to be expressed in …

Photons during the dark period delay flowering in short-day plants (SDP). Red photons applied at night convert phytochromes to the active far-red absorbing form (Pfr), leading to inhibition of flowering. Far-red photons (greater than 700 nm) re-induce flowering when applied after a pulse of red photons during the dark period. However, far-red photons at sufficiently high intensity and duration delay flowering in sensitive species. Mechanistically, this response occurs because phytochrome-red (Pr) absorbance is not zero beyond 700 nm. We applied nighttime photons from near infrared (NIR) LEDs (peak 850 nm) over a 12 h dark period. …
On The Relationship Between North India Summer Monsoon Rainfall And East Equatorial Indian Ocean Warming, Ramesh Kumar Yadav, Mathew Koll Roxy
On The Relationship Between North India Summer Monsoon Rainfall And East Equatorial Indian Ocean Warming, Ramesh Kumar Yadav, Mathew Koll Roxy

Generally, a strong north India summer-monsoon rainfall (NISR) is associated with anomalous upper troposphere ridge over northwest of India. This ridge triggers anomalous northerly winds over Tibetan Plateau and easterlies over India. The easterly anomaly over India reduces the tropospheric wind shear, while the northerly at Tibetan plateau allows frequent intrusions of high-latitude dry and cold meridional winds to interact with the lower-level relatively warm and moist easterly monsoonal flow, enhancing the NISR. The current study, using a suite of observations, reanalysis products and numerical model sensitivity experiments, explores the changes in NISR, and its association with the warming in …
Critical Temperature For Sub-Lethal Cold Injury Of Strawberry Leaves, Tiffany L. Maughan, Brent Black, Daniel Drost
Critical Temperature For Sub-Lethal Cold Injury Of Strawberry Leaves, Tiffany L. Maughan, Brent Black, Daniel Drost
Plants, Soils and Climate Student Research
Freezing temperatures are a major limitation to strawberry production in temperate regions, and protected-cultivation strategies such as the use of tunnels and row covers are used to overcome this limitation. In order to optimize management under protected cultivation, it is necessary to understand the damage thresholds for strawberry plant tissues. The effects of freezing temperatures (−3, −5, and −7 °C) on leaf CO2 assimilation were evaluated for ‘Chandler’, ‘Seascape’ and ‘Jewel’ strawberry (Fragaria × ananassa). Growth chambers were used to expose plants to freezing temperatures under carefully defined conditions. Net assimilation was then measured on the cold-exposed …
