Context-dependent effects of Trichoderma seed inoculation on anthracnose disease and seed yield of bean (Phaseolus vulgaris): ambient conditions override cultivar-specific differences
<p>Root colonizing <i>Trichoderma </i>fungi can stimulate plant immunity, but net effects are strain × cultivar-specific and changing ambient conditions further contribute to variable outcomes. Here, we used four <i>Trichoderma</i> spp. to inoculate seeds of four common bean (<i>Phaseolus vulgaris</i>) cultivars and explored in three different experimental setups the effects on fungal anthracnose after leaf inoculation with <i>Colletotrichum lindemuthianum</i>. Plants growing in pots with field soil under greenhouse conditions exhibited the highest and those in the open field the lowest overall levels of disease. Among 48 <i>Trichoderma</i> strain × bean cultivar × setup combinations, <i>Trichoderma</i>-inoculation enhanced disease in six and decreased disease in ten cases, but with the exception of <i>T. asperellum</i> B6-inoculated Negro San Luis beans, the strain × cultivar-specific effects on anthracnose severity differed among the setups, and anthracnose severity did not predict seed yield in the open field. In the case of Flor de Mayo beans, <i>Trichoderma</i> even reduced yield in anthracnose-free field plots, although this effect was counterbalanced in anthracnose-infected plots. We consider our work as a case study that calls for stronger emphasis on field experiments in the early phases of screenings of <i>Trichoderma</i> inoculants as plant biostimulants.</p>

Data for: Morphological and molecular characterization of variation in common bean (Phaseolus vulgaris L.) germplasm from Azad Jammu and Kashmir, Pakistan
<p><em>Phaseolus vulgaris</em>, an essential food and source of protein, is cultivated across the world. This study was carried out to investigate the diversity and population structure of 34 P. vulgaris landrace accessions collected from the Azad Jammu and Kashmir (AJ&K) regions of Pakistan. The samples were analyzed both morphologically and using genetic variation identified through RNA sequencing. Our results indicated that most genetic variation occurs among local accessions, with little genetic variation occurring between geographical regions. In addition, the accessions fell into two major genetic groups. Morphological analysis revealed that these two genetic groups differ in a number of quantitative traits, including seed length, seed width, and seed weight. One accession, DUD-11, appears to be a mixture of the two major groups genetically as well as morphologically. Among the other accessions, DUD-8, RWK-2, and NGD-1 depicted particularly high seed weight along with higher seed length, seed width, and seed yield per plant. We suggest focusing on these accessions in future breeding programs. More generally, our results provide baseline data that will be useful for crop improvement and effective cultivation practices in Pakistan.</p>

Demography of Tetranychus urticae (Acari: Tetranychidae) on Phaseolus vulgaris (Fabales: Fabaceae) under Different Nitrogen Fertilization Regimes with Estimations of Confidence Intervals
<p>The life table raw data and output files:</p> <p>In order to study the effect of nitrogen fertilization on the population growth rate of two-spotted spider mite, <em>Tetranychus urticae</em> Koch (Acari: Tetranychidae), life table data on common bean were collected. Bean plants were treated with four nitrogen levels (0, 75, 150, and 225 kg N ha<sup>-1</sup>). Data were analyzed based on the age-stage, two-sex life table program.</p>
